Question 1
All humming birds are beautiful, but they are found only in the Western hemisphere. The crest of the tiny head of one of these shines like a sparkling crown of coloured light. The shades of color that adorn its breast are equally brilliant. As the bird flits from one object to another, it looks more like a bright flash of sunlight than it does like a living being.
But why are humming birds so called? It is because they make a soft, humming noise by the rapid motion of their wings - a motion so rapid, that as they fly, you can hardly see that they have wings.
A hummingbird's brain makes up a whopping 4.2 percent of its weight; proportionally, that's the largest of any bird's (By comparison, our brains are 2 percent of our body weight). Inside that big brain is a veritable encyclopaedia of important information. Studies have shown that hummingbirds can remember every flower they've ever visited, including on migration routes. They can figure out how long to wait between visits, so the flowers have time to generate more nectar. They can even recognize humans and know which ones can be counted on to refill empty hummingbird feeders.
Hummingbirds have terrific vision: They can see every colour we can, and their eyes can process ultraviolet light, which means they can also see some colours we can't. On top of that, hummingbirds are among the many animals gifted with a third set of eyelids. These translucent flaps of skin known as nictitating membranes act like natural flight goggles, protecting the hummingbird's eyes as the little bird zooms through the air.
No other bird on Earth can stunt-fly like a hummingbird. They can fly forward or backward, hover, and even fly upside-down, and they do all of this so fast we can't even see it - beating their wings between 70 and 200 times per second. This power, precision, and agility allows them to reach speeds of up to 30 miles per hour while flying and 60 miles per hour while diving. Their mad flight skills have made them a subject of great scientific fascination.
The nest of the smaller humming birds is about half the size of a very small hen's egg, and it is attached to a twig no thicker than a steel knitting needle. It seems to have been made of cotton fibres and is covered with the softest bits of leaf and bark. The eggs in it may be about as large as a small sugarplum.
When you approach the spot where one of these birds has built its nest, it is necessary to be careful. The mother bird will dart at you and try to peck your eyes. Its sharp beak may hurt your eyes most severely, and even destroy your sight. The poor little thing knows no other way of defending its young, and instinct teaches it that you might carry off its nest if you find it.
However, if a humming bird buzzes around your face, it probably is attracted to your eyes, and not because it intends to puncture them with its needle-shaped bill (which is more like a straw than a stiletto). Many animals instinctively associate large, forward-facing eyes with predators, and hummingbirds, being both intelligent and masters of evasion, will often approach potential predators to size up the threat. If the object of interest proves to be something dangerous - a cat, an owl, a snake, a Chinese mantid - a common response is to harass the predator from a (hopefully) safe position while raising the alarm to attract other birds.
What could be the reasons behind a humming bird buzzing around someone’s face and trying to peck the eyes?
I. It is attracted to the person’s eyes.
II. It may be sizing up threat from a potential predator.
III. The method is a way of defending its young ones.
Correct! The correct answer is E: All I, II and III. The passage states that hummingbirds are attracted to eyes, size up potential predators, and defend their young by pecking eyes.
Meanings of the options:
1. I only: “only the first statement” || “केवल पहला कथन”
2. III only: “only the third statement” || “केवल तीसरा कथन”
3. Both I and III: “first and third statements” || “पहला और तीसरा कथन”
4. Both II and III: “second and third statements” || “दूसरा और तीसरा कथन”
5. All I, II and III: “all three statements” || “सभी तीन कथन”

5. None of these: “not any of the above” || “इनमें से कोई नहीं”

Question 8
When candles burn, most of their matter go into the air. The light and heat from a candle comes from the wax burning. When you light the wick, the flame causes some of the wax to melt, and then the wax vapour burns. The wick, which is made of cotton, also burns, although it's the wax that contributes most of the heat. The puddles you sometimes see around the base are from wax that spilled and dripped down without burning. Wax is made of hydrogen and carbon. When a candle burns, the hydrogen and carbon from the wax combine with the oxygen in the air to become carbon dioxide and water vapour. Most of the matter in the candle ends up as these two gases.
Carbon dioxide and water aren't exactly safe but at low levels they are normal parts of the air. The amount of each gas produced by a candle is small - comparable to the amount that might be breathed out by another person in the room. If candles burned completely, every molecule from the wax would end up combining with oxygen to become CO₂ or water vapour, but candles don't burn perfectly. Around the edges of the flame, clumps of carbon molecules - maybe 0.1 percent of the mass of the candle - are flung away before they finish burning, sort of like bits of food sprayed out by a kitchen mixer. These particles contribute to smoke and soot.
Aneta Wierzbicka, a scientist, "Candles, in homes without tobacco smoking, are among the most powerful indoor sources of particles, followed by cooking," told me. She said that constant exposure to these tiny particles can lead to cardiovascular and respiratory diseases. She said, it's worth taking steps to minimize exposure to airborne particles. She suggests making sure the room is well-ventilated, and using clean, white candles without too many additives or ingredients, since everything in the candle ends up in the air. As a candle burns, the CO₂ and water vapour it produces will cool and mix into the air in the room, becoming indistinguishable from any other molecule of CO₂ or water. Over the next few hours, as the air in your room is exchanged with the air outdoors. After about a year, atoms from your candle will have spread completely around the globe. For the next few years, every time someone takes a breath of air, they'll be breathing in a few carbon atoms from the wax and a few oxygen atoms from the air in your room.
As per the passage, which of the following is not a statement made by the scientist Aneta Wierzbicka?
Correct! The correct answer is C: Candles are not responsible for producing harmful gases like carbon dioxide. The passage states that candles do produce carbon dioxide, so this statement is not made by the scientist.

3. Candles are not responsible for producing harmful gases like carbon dioxide: “candles do not produce CO₂” || “मोमबत्तियाँ CO₂ उत्पन्न नहीं करतीं”
4. One of the strong sources of formation of flaky substance at home is candle: “candles are a strong source of particles” || “मोमबत्तियाँ कणों का प्रबल स्रोत हैं”
5. Increased risk of cardiovascular diseases due to persistent exposure to particles formed by burning candles: “exposure increases heart disease risk” || “संपर्क से हृदय रोग का खतरा”

Question 1 of 15Marks: +1 and -0.25
1. Question
Section: English00:00Read the following passage carefully and answer the questions that follow.
All humming birds are beautiful, but they are found only in the Western hemisphere. The crest of the tiny head of one of these shines like a sparkling crown of coloured light. The shades of color that adorn its breast are equally brilliant. As the bird flits from one object to another, it looks more like a bright flash of sunlight than it does like a living being.
But why are humming birds so called? It is because they make a soft, humming noise by the rapid motion of their wings - a motion so rapid, that as they fly, you can hardly see that they have wings.
A hummingbird's brain makes up a whopping 4.2 percent of its weight; proportionally, that's the largest of any bird's (By comparison, our brains are 2 percent of our body weight). Inside that big brain is a veritable encyclopaedia of important information. Studies have shown that hummingbirds can remember every flower they've ever visited, including on migration routes. They can figure out how long to wait between visits, so the flowers have time to generate more nectar. They can even recognize humans and know which ones can be counted on to refill empty hummingbird feeders.
Hummingbirds have terrific vision: They can see every colour we can, and their eyes can process ultraviolet light, which means they can also see some colours we can't. On top of that, hummingbirds are among the many animals gifted with a third set of eyelids. These translucent flaps of skin known as nictitating membranes act like natural flight goggles, protecting the hummingbird's eyes as the little bird zooms through the air.
No other bird on Earth can stunt-fly like a hummingbird. They can fly forward or backward, hover, and even fly upside-down, and they do all of this so fast we can't even see it - beating their wings between 70 and 200 times per second. This power, precision, and agility allows them to reach speeds of up to 30 miles per hour while flying and 60 miles per hour while diving. Their mad flight skills have made them a subject of great scientific fascination.
The nest of the smaller humming birds is about half the size of a very small hen's egg, and it is attached to a twig no thicker than a steel knitting needle. It seems to have been made of cotton fibres and is covered with the softest bits of leaf and bark. The eggs in it may be about as large as a small sugarplum.
When you approach the spot where one of these birds has built its nest, it is necessary to be careful. The mother bird will dart at you and try to peck your eyes. Its sharp beak may hurt your eyes most severely, and even destroy your sight. The poor little thing knows no other way of defending its young, and instinct teaches it that you might carry off its nest if you find it.
However, if a humming bird buzzes around your face, it probably is attracted to your eyes, and not because it intends to puncture them with its needle-shaped bill (which is more like a straw than a stiletto). Many animals instinctively associate large, forward-facing eyes with predators, and hummingbirds, being both intelligent and masters of evasion, will often approach potential predators to size up the threat. If the object of interest proves to be something dangerous - a cat, an owl, a snake, a Chinese mantid - a common response is to harass the predator from a (hopefully) safe position while raising the alarm to attract other birds.What could be the reasons behind a humming bird buzzing around someone’s face and trying to peck the eyes?
I. It is attracted to the person’s eyes.
II. It may be sizing up threat from a potential predator.
III. The method is a way of defending its young ones.

They can fly forward or backward, hover, and even fly upside-down, and they do all of this so fast we can't even see it - beating their wings between 70 and 200 times per second. This power, precision, and agility allows them to reach speeds of up to 30 miles per hour while flying and 60 miles per hour while diving. Their mad flight skills have made them a subject of great scientific fascination.
The nest of the smaller humming birds is about half the size of a very small hen's egg, and it is attached to a twig no thicker than a steel knitting needle. It seems to have been made of cotton fibres and is covered with the softest bits of leaf and bark. The eggs in it may be about as large as a small sugarplum.
When you approach the spot where one of these birds has built its nest, it is necessary to be careful. The mother bird will dart at you and try to peck your eyes. Its sharp beak may hurt your eyes most severely, and even destroy your sight. The poor little thing knows no other way of defending its young, and instinct teaches it that you might carry off its nest if you find it.
However, if a humming bird buzzes around your face, it probably is attracted to your eyes, and not because it intends to puncture them with its needle-shaped bill (which is more like a straw than a stiletto). Many animals instinctively associate large, forward-facing eyes with predators, and hummingbirds, being both intelligent and masters of evasion, will often approach potential predators to size up the threat. If the object of interest proves to be something dangerous - a cat, an owl, a snake, a Chinese mantid - a common response is to harass the predator from a (hopefully) safe position while raising the alarm to attract other birds.Which of the following is the actual reason for humming birds to have been given that name?
Correct
Correct! The correct answer is C: They make a soft, humming noise by the rapid motion of their wings. The passage states that hummingbirds are so called because they make a soft, humming noise by the rapid motion of their wings.

3. Question
Section: English00:00Read the following passage carefully and answer the questions that follow.
All humming birds are beautiful, but they are found only in the Western hemisphere. The crest of the tiny head of one of these shines like a sparkling crown of coloured light. The shades of color that adorn its breast are equally brilliant. As the bird flits from one object to another, it looks more like a bright flash of sunlight than it does like a living being.
But why are humming birds so called? It is because they make a soft, humming noise by the rapid motion of their wings - a motion so rapid, that as they fly, you can hardly see that they have wings.
A hummingbird's brain makes up a whopping 4.2 percent of its weight; proportionally, that's the largest of any bird's (By comparison, our brains are 2 percent of our body weight). Inside that big brain is a veritable encyclopaedia of important information. Studies have shown that hummingbirds can remember every flower they've ever visited, including on migration routes. They can figure out how long to wait between visits, so the flowers have time to generate more nectar. They can even recognize humans and know which ones can be counted on to refill empty hummingbird feeders.
Hummingbirds have terrific vision: They can see every colour we can, and their eyes can process ultraviolet light, which means they can also see some colours we can't. On top of that, hummingbirds are among the many animals gifted with a third set of eyelids. These translucent flaps of skin known as nictitating membranes act like natural flight goggles, protecting the hummingbird's eyes as the little bird zooms through the air.
No other bird on Earth can stunt-fly like a hummingbird. They can fly forward or backward, hover, and even fly upside-down, and they do all of this so fast we can't even see it - beating their wings between 70 and 200 times per second.

8. Question
Section: English00:00Read the following passage carefully and answer the questions that follow.
When candles burn, most of their matter go into the air. The light and heat from a candle comes from the wax burning. When you light the wick, the flame causes some of the wax to melt, and then the wax vapour burns. The wick, which is made of cotton, also burns, although it's the wax that contributes most of the heat. The puddles you sometimes see around the base are from wax that spilled and dripped down without burning. Wax is made of hydrogen and carbon. When a candle burns, the hydrogen and carbon from the wax combine with the oxygen in the air to become carbon dioxide and water vapour. Most of the matter in the candle ends up as these two gases.
Carbon dioxide and water aren't exactly safe but at low levels they are normal parts of the air. The amount of each gas produced by a candle is small - comparable to the amount that might be breathed out by another person in the room. If candles burned completely, every molecule from the wax would end up combining with oxygen to become CO₂ or water vapour, but candles don't burn perfectly. Around the edges of the flame, clumps of carbon molecules - maybe 0.1 percent of the mass of the candle - are flung away before they finish burning, sort of like bits of food sprayed out by a kitchen mixer. These particles contribute to smoke and soot.
Aneta Wierzbicka, a scientist, "Candles, in homes without tobacco smoking, are among the most powerful indoor sources of particles, followed by cooking," told me. She said that constant exposure to these tiny particles can lead to cardiovascular and respiratory diseases. She said, it's worth taking steps to minimize exposure to airborne particles. She suggests making sure the room is well-ventilated, and using clean, white candles without too many additives or ingredients, since everything in the candle ends up in the air. As a candle burns, the CO₂ and water vapour it produces will cool and mix into the air in the room, becoming indistinguishable from any other molecule of CO₂ or water. Over the next few hours, as the air in your room is exchanged with the air outdoors. After about a year, atoms from your candle will have spread completely around the globe. For the next few years, every time someone takes a breath of air, they'll be breathing in a few carbon atoms from the wax and a few oxygen atoms from the air in your room.As per the passage, which of the following is not a statement made by the scientist Aneta Wierzbicka?
Correct
Correct! The correct answer is C: Candles are not responsible for producing harmful gases like carbon dioxide. The passage states that candles do produce carbon dioxide, so this statement is not made by the scientist.
Meanings of the options:
1. Having a proper ventilation system at home can save us all from the harmful gases produced by burning candles: “ventilation helps reduce exposure” || “उचित वेंटिलेशन से हानिकारक गैसों से बचाव”
2. Regular exposure to particles formed by burning candles can lead to respiratory diseases: “exposure causes respiratory diseases” || “कणों के संपर्क से श्वसन रोग”
3. Candles are not responsible for producing harmful gases like carbon dioxide: “candles do not produce CO₂” || “मोमबत्तियाँ CO₂ उत्पन्न नहीं करतीं”
4. One of the strong sources of formation of flaky substance at home is candle: “candles are a strong source of particles” || “मोमबत्तियाँ कणों का प्रबल स्रोत हैं”
5. Increased risk of cardiovascular diseases due to persistent exposure to particles formed by burning candles: “exposure increases heart disease risk” || “संपर्क से हृदय रोग का खतरा”

9. Question
Section: English00:00Read the following passage carefully and answer the questions that follow.
When candles burn, most of their matter go into the air. The light and heat from a candle comes from the wax burning. When you light the wick, the flame causes some of the wax to melt, and then the wax vapour burns. The wick, which is made of cotton, also burns, although it's the wax that contributes most of the heat. The puddles you sometimes see around the base are from wax that spilled and dripped down without burning. Wax is made of hydrogen and carbon. When a candle burns, the hydrogen and carbon from the wax combine with the oxygen in the air to become carbon dioxide and water vapour. Most of the matter in the candle ends up as these two gases.
Carbon dioxide and water aren't exactly safe but at low levels they are normal parts of the air. The amount of each gas produced by a candle is small - comparable to the amount that might be breathed out by another person in the room. If candles burned completely, every molecule from the wax would end up combining with oxygen to become CO₂ or water vapour, but candles don't burn perfectly. Around the edges of the flame, clumps of carbon molecules - maybe 0.1 percent of the mass of the candle - are flung away before they finish burning, sort of like bits of food sprayed out by a kitchen mixer. These particles contribute to smoke and soot.

15. Question
Section: English00:00Read the following passage carefully and answer the questions that follow.
When candles burn, most of their matter go into the air. The light and heat from a candle comes from the wax burning. When you light the wick, the flame causes some of the wax to melt, and then the wax vapour burns. The wick, which is made of cotton, also burns, although it's the wax that contributes most of the heat. The puddles you sometimes see around the base are from wax that spilled and dripped down without burning. Wax is made of hydrogen and carbon. When a candle burns, the hydrogen and carbon from the wax combine with the oxygen in the air to become carbon dioxide and water vapour. Most of the matter in the candle ends up as these two gases.
Carbon dioxide and water aren't exactly safe but at low levels they are normal parts of the air. The amount of each gas produced by a candle is small - comparable to the amount that might be breathed out by another person in the room. If candles burned completely, every molecule from the wax would end up combining with oxygen to become CO₂ or water vapour, but candles don't burn perfectly. Around the edges of the flame, clumps of carbon molecules - maybe 0.1 percent of the mass of the candle - are flung away before they finish burning, sort of like bits of food sprayed out by a kitchen mixer. These particles contribute to smoke and soot.
Aneta Wierzbicka, a scientist, "Candles, in homes without tobacco smoking, are among the most powerful indoor sources of particles, followed by cooking," told me. She said that constant exposure to these tiny particles can lead to cardiovascular and respiratory diseases. She said, it's worth taking steps to minimize exposure to airborne particles. She suggests making sure the room is well-ventilated, and using clean, white candles without too many additives or ingredients, since everything in the candle ends up in the air. As a candle burns, the CO₂ and water vapour it produces will cool and mix into the air in the room, becoming indistinguishable from any other molecule of CO₂ or water. Over the next few hours, as the air in your room is exchanged with the air outdoors. After about a year, atoms from your candle will have spread completely around the globe. For the next few years, every time someone takes a breath of air, they'll be breathing in a few carbon atoms from the wax and a few oxygen atoms from the air in your room.As per the given passage, which of the following is untrue?
Correct
Correct! The correct answer is B: Every bit of a candle is burnt when lit. The passage states that candles don’t burn perfectly and some matter remains unburned, so this statement is untrue.
Meanings of the options:
1. A burning candle is capable of producing light and heat: “produces light and heat” || “जलती मोमबत्ती प्रकाश और गर्मी उत्पन्न करती है”
2. Every bit of a candle is burnt when lit: “completely burnt” || “मोमबत्ती का हर हिस्सा जलता है”
3. Most of the matter enters the air when a candle is burnt: “most matter goes into the air” || “अधिकांश पदार्थ हवा में चला जाता है”
4. Unburned mass of a candle forms harmful particles: “unburned mass forms particles” || “अजला द्रव्यमान हानिकारक कण बनाता है”
5. Two gases are mostly produced while burning a candle: “two gases are produced” || “दो गैसें उत्पन्न होती हैं”
