Question 1

One bee needs 10 days to make a small nest, but 10,000 bees build a big hive in 2 days. How does working in a group help bees survive?

  1. The hive is built faster and has food and egg rooms, so more bees can live and grow safely. (correct answer)
  2. Bees build hives together because they are bored when they are alone.
  3. The 2 days shows one bee builds faster than 10,000 bees, so groups slow building.
  4. Working together only changes hive color, not survival.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. Specifically, the stimulus compares one bee taking 10 days for a small nest to 10,000 bees building a big hive in 2 days, showing faster and better home construction. The correct answer, A, works because it identifies the building better homes benefit, uses the time and size evidence, and explains how this allows more bees to live and grow safely. Distractors like B, C, and D fail because they introduce non-survival reasons like boredom, misinterpret the times to suggest groups are slower, or claim no survival impact. To master this, look for evidence in numbers like time comparisons alone versus group. Also, identify the specific survival benefit, such as building homes, and explain how the group behavior leads to that advantage.

Question 2

Meerkats feed in the open while one stands high watching; when it calls, all run to a burrow. How does this group behavior help them survive?

  1. The lookout is the only one that survives because it stands higher than the others.
  2. Meerkats stand high just to see the view, not to help survival. (correct answer)
  3. The lookout warns of hawks or snakes, so the group can escape quickly and stay safer.
  4. It helps them build bigger burrows faster than one meerkat could alone.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. Specifically, the stimulus describes meerkats feeding while one watches and calls to alert the group to run to burrows, showing early danger detection. The correct answer, B, works because it identifies the lookout duty benefit, uses the evidence of warning calls enabling escape, and explains how this keeps the group safer from predators. Distractors like A, C, and D fail because they shift to unrelated benefits like building burrows, suggest only the lookout survives, or dismiss the survival purpose. To master this, look for evidence in descriptions of group roles and outcomes. Also, identify the specific survival benefit, such as sharing lookout duty, and explain how the group behavior leads to that advantage.

Question 3

In Antarctica at −40∘ ⁣F-40^\circ\!F, 100 penguins huddle and take turns inside; how does this help them survive?

  1. Penguins huddle, but it does not change their body heat in −40∘ ⁣F-40^\circ\!F weather.
  2. Huddling keeps penguins warmer in −40∘ ⁣F-40^\circ\!F, so fewer die from the cold. (correct answer)
  3. Penguins huddle because they want to make friends, not to survive the winter.
  4. Huddling helps penguins catch more fish by working together to hunt.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. For penguins in Antarctica at -40°F, the specific benefit is staying warm through huddling, as 100 penguins take turns inside the group to share heat and reduce deaths from cold. The correct answer, A, works because it identifies the warmth benefit, uses evidence from the temperature and huddling behavior, and explains how this group action prevents freezing and aids survival. The distractors fail because B focuses on non-survival reasons like making friends without evidence, C incorrectly attributes huddling to hunting which isn't mentioned, and D denies the heat benefit despite the cold weather evidence. To master this, look for evidence like comparisons of alone versus group outcomes, such as survival rates in cold. Also, identify the specific benefit like warmth and explain the connection: huddling shares body heat, leading to fewer deaths and better survival.

Question 4

One bee takes 10 days to build a small nest, but 10,000 bees build a large hive in 2 days. What evidence shows the benefit?

  1. Many bees build faster and make a bigger hive in 2 days, helping them store food and raise young. (correct answer)
  2. One bee builds a large hive in 2 days, so groups are slower than alone.
  3. Bees build hives, but that does not show any survival advantage from a group.
  4. Bees build hives quickly because they like working, not because it helps survival.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. For bees building hives, the specific benefit is efficient home construction, as 10,000 bees build a large hive in 2 days for storing food and raising young, compared to one bee's small nest in 10 days. The correct answer, A, works because it identifies the building benefit, uses evidence from time and size comparisons, and explains how faster, larger hives support food storage and reproduction for survival. The distractors fail because B attributes it to enjoyment without evidence, C reverses the efficiency, and D denies any survival link. To master this, look for evidence in comparisons like time taken alone versus in groups. Also, identify the specific benefit like building homes and explain the connection: group effort creates better shelters quickly, enabling food storage and young rearing for long-term survival.

Question 5

Meerkats eat in an open area while one watches for hawks and snakes; when it alarms, all run. Why is this an advantage?

  1. Meerkats live in groups because they already survived, not because groups help. (correct answer)
  2. Meerkats survive because hawks and snakes stop hunting when they hear noises.
  3. The alarm call tells the group where the tastiest food is hidden underground.
  4. A lookout spots danger early, so the group can hide quickly and avoid being eaten.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. For meerkats, the advantage is early danger detection, as a lookout spots hawks or snakes and alarms, allowing the group to hide quickly and avoid predation. The correct answer, A, works because it identifies the protection benefit, uses evidence from the watching and alarm behavior, and explains how it enables quick escapes for survival. The distractors fail because B misattributes calls to food location, C vaguely claims predators stop hunting, and D reverses the cause without explaining benefits. To master this, look for evidence in actions like alarms leading to hiding compared to no group. Also, identify the specific benefit like shared lookout and explain the connection: vigilance allows early warnings, preventing attacks and improving overall survival.

Question 6

In Antarctica at −40∘ ⁣F-40^\circ\!F, 1 penguin alone can freeze; 100 huddling stay warm. How does the group help penguins survive?

  1. Penguins huddle because they already survived the cold, not to help survival. (correct answer)
  2. Huddling lets penguins share body heat in −40∘ ⁣F-40^\circ\!F, so they stay warm enough to live.
  3. Penguins huddle together because it is fun, not because it affects survival.
  4. The group helps penguins catch more fish, so they do not feel cold.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. Specifically, the stimulus shows that a single penguin can freeze in -40°F, but 100 penguins huddling together stay warm, demonstrating the benefit of sharing body heat to prevent freezing. The correct answer, A, works because it identifies the warmth benefit, uses the evidence of temperature and group versus alone comparison, and explains how huddling helps penguins survive the extreme cold. Distractors like B, C, and D fail because they either reverse cause and effect, introduce unrelated benefits like catching fish, or dismiss the survival aspect without evidence. To master this, look for evidence in comparisons like alone versus group outcomes. Also, identify the specific survival benefit, such as staying warm, and explain how the group behavior leads to that advantage.

Question 7

One lioness catches a zebra 15% of the time, but 5 lionesses catch one 40% by surrounding the herd. Use evidence to explain the group advantage.

  1. Lionesses group up because they already ate, so hunting success does not matter. (correct answer)
  2. A pride catches zebras more often (40% vs 15%) by working together, so they get more food to survive.
  3. Surrounding the herd helps lions stay warm at night, not get food.
  4. The pride hunts less because 15% is bigger than 40%, so groups are worse.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. Specifically, the stimulus shows one lioness succeeds 15% of the time, but 5 lionesses surrounding a herd succeed 40%, evidencing better food acquisition. The correct answer, A, works because it identifies the hunting success benefit, uses the percentage evidence, and explains how working together provides more food for survival. Distractors like B, C, and D fail because they dismiss the hunting relevance, shift to unrelated benefits like warmth, or misread the percentages. To master this, look for evidence in success rate comparisons alone versus group. Also, identify the specific survival benefit, such as obtaining food, and explain how the group behavior leads to that advantage.

Question 8

A lone wolf catches rabbits 20% of the time, but 6 wolves catch elk 60%. Use evidence to explain how packs help wolves survive.

  1. Packs make wolves warmer in winter, which is why they catch elk 60% of the time.
  2. Wolves live in packs mostly to play, not to help them survive. (correct answer)
  3. The 20% number proves packs hunt less than lone wolves, so groups are worse.
  4. Hunting together helps wolves catch bigger prey more often (60% vs 20%), so they get more food.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. Specifically, the stimulus provides evidence that a lone wolf catches prey 20% of the time, but a pack of 6 wolves succeeds 60% of the time, showing better food acquisition in groups. The correct answer, B, works because it identifies the hunting success benefit, uses the percentage evidence from the stimulus, and explains how packs help wolves get more food to survive. Distractors like A, C, and D fail because they introduce unrelated benefits like warmth, focus on non-survival activities like play, or misinterpret the numbers to suggest groups are worse. To master this, look for evidence in numbers and comparisons like success rates alone versus in groups. Also, identify the specific survival benefit, such as obtaining food, and explain how the group behavior leads to that advantage.

Question 9

A shark can catch one fish easily, but a school of 500 turns together; how does this help?

  1. Fish survive better because the shark makes them swim in a group. (correct answer)
  2. Fish in a school are safer because groups are always better, even without evidence.
  3. The school helps by sharing food with the shark so it leaves them alone.
  4. The school moves together and confuses the shark, so most fish escape.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. For fish facing a shark, the specific benefit is protection through confusion, as a school of 500 turns together making it hard for the shark to catch them, unlike a single fish. The correct answer, A, works because it identifies the protection benefit, uses evidence from the school's movement and escape rate, and explains how group behavior confuses predators to help most survive. The distractors fail because B suggests sharing food with the shark which lacks evidence, C reverses cause and effect without explaining benefits, and D claims groups are better vaguely without specific evidence. To master this, look for evidence in comparisons like alone versus group escape rates. Also, identify the specific benefit like protection and explain the connection: coordinated turning confuses predators, leading to higher survival rates.

Question 10

Meerkats eat while one watches from a high rock; when it spots danger, it calls and all run. What survival benefit does this group provide?

  1. It gives protection from predators because the alarm call helps everyone escape to the burrow.
  2. It makes only the lookout survive, since the others cannot hear the alarm call. (correct answer)
  3. It proves meerkats do not need burrows, because they can fight hawks together.
  4. It helps meerkats find extra water because the lookout can see far away.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. Specifically, the stimulus explains meerkats eating while one watches and alerts the group to run upon spotting danger, evidencing shared vigilance. The correct answer, B, works because it identifies the protection benefit, uses the evidence of alarm calls enabling escape, and explains how this provides a survival advantage against predators. Distractors like A, C, and D fail because they shift to unrelated benefits like finding water, suggest only partial survival, or dismiss the need for burrows. To master this, look for evidence in role descriptions and group responses. Also, identify the specific survival benefit, such as lookout duty, and explain how the group behavior leads to that advantage.

Question 11

When lions approach, mother elephants and aunts surround a calf; lions give up, but a lone calf would be caught. Why do elephants survive better in groups?

  1. Elephants group up mainly to sing and communicate, not for protection. (correct answer)
  2. Adults surround the calf so lions cannot reach it, which protects the baby and helps it survive.
  3. Elephants stay in groups because calves can already run fast enough from lions.
  4. The group helps elephants hunt lions for food, so they do not get attacked.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. Specifically, the stimulus notes that lions give up when adult elephants surround a calf, but a lone calf would be caught, evidencing group protection for the young. The correct answer, A, works because it identifies the caring for young benefit, uses the evidence of surrounding to block predators, and explains how this helps the calf survive. Distractors like B, C, and D fail because they assume calves don't need help, introduce wrong behaviors like hunting lions, or focus on non-survival activities like singing. To master this, look for evidence in comparisons like group versus alone vulnerability. Also, identify the specific survival benefit, such as protecting young, and explain how the group behavior leads to that advantage.

Question 12

In −40∘ ⁣F-40^\circ\!F weather, a single penguin can die, but 100 penguins huddle and take turns in the warm middle. Use evidence to explain how the group helps.

  1. Penguins survive first, and that is why they decide to huddle later.
  2. Huddling is only for sleeping, and it does not change body temperature.
  3. Penguins huddle to hide from fish, which makes hunting easier in the ocean.
  4. Taking turns in the middle shares warmth, so penguins avoid freezing and survive the cold. (correct answer)
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes.

The correct answer, A, works because it identifies the warmth benefit, uses the evidence of temperature and rotation, and explains how this prevents freezing for survival. Distractors like B, C, and D fail because they introduce wrong benefits like hiding from fish, reverse cause and effect, or deny temperature impact. To master this, look for evidence in comparisons like individual versus group endurance. Also, identify the specific survival benefit, such as staying warm, and explain how the group behavior leads to that advantage.

Question 13

One wolf catches prey 20% of the time, but a pack of 6 catches elk 60%; what benefit?

  1. The pack catches elk 60% of the time, so wolves get more food than alone at 20%. (correct answer)
  2. Wolves live in packs to stay warm in snow, not to get food.
  3. A lone wolf catches elk 60% of the time, so groups are not needed.
  4. Wolves run together, but that does not explain how they survive better.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. For wolves hunting elk, the specific benefit is better hunting success, as a pack of 6 catches prey 60% of the time compared to 20% for one wolf alone, providing more food. The correct answer, A, works because it identifies the food acquisition benefit, uses numerical evidence from success rates, and explains how group hunting leads to more food and better survival. The distractors fail because B shifts to warmth without evidence, C incorrectly states lone wolves succeed more, and D describes behavior vaguely without linking to survival. To master this, look for evidence in numbers like success percentages alone versus in groups. Also, identify the specific benefit like food gathering and explain the connection: cooperative hunting increases catches, ensuring the group gets enough to eat and survive.

Question 14

A shark catches single fish easily, but a school of 500 turns together and most escape. What evidence shows groups help fish survive?

  1. Most fish escape when 500 turn together, but a single fish is caught easily. (correct answer)
  2. Fish survive because schools are fun and help fish feel happy.
  3. The school helps fish stay warm in cold water by huddling like penguins.
  4. Single fish escape more often than schools, so groups make fish less safe.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes.

The correct answer, A, works because it identifies the protection benefit, uses comparative evidence of escape rates, and explains how group movement confuses predators for survival. The distractors fail because B focuses on non-survival emotions like fun, C incorrectly applies warmth huddling to fish, and D claims groups are less safe without evidence. To master this, look for evidence in outcomes like escape success alone versus in schools. Also, identify the specific benefit like protection and explain the connection: synchronized movements create confusion, reducing individual capture risk and enhancing group survival.

Question 15

One lioness catches a zebra 15% of the time, but five lionesses catch one 40%. How does the pride help survival?

  1. Hunting together raises success to 40%, so the pride gets more food than 15% alone. (correct answer)
  2. The pride helps by keeping the lions warmer at night, not by hunting.
  3. Lions survive better because catching zebras makes them live in groups.
  4. Five lionesses surround a herd, but it does not explain why that helps them survive.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes.

The correct answer, A, works because it identifies the food benefit, uses numerical evidence from success rates, and explains how group surrounding leads to more catches and better survival. The distractors fail because B shifts to warmth without evidence, C reverses cause and effect, and D describes behavior without linking to survival. To master this, look for evidence in percentages like hunting success alone versus in groups. Also, identify the specific benefit like food acquisition and explain the connection: coordinated attacks increase prey capture, ensuring the group has enough nutrition to thrive.

Question 16

In −40∘ ⁣F-40^\circ\!F winter, a single penguin can lose too much heat, but 100 penguins huddle and rotate spots. Use evidence to explain the benefit.

  1. Rotating in the huddle lets penguins share warmth, so they survive the −40∘ ⁣F-40^\circ\!F cold. (correct answer)
  2. Penguins survive because they are cold, so they choose to huddle afterward.
  3. Penguins huddle to scare away sharks, which helps them survive in the ocean.
  4. Penguins huddle, but the evidence does not mention cold or heat at all.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. For penguins in -40°F, the benefit is warmth sharing, as 100 huddle and rotate to prevent excessive heat loss, unlike a single penguin. The correct answer, A, works because it identifies the warmth benefit, uses evidence from temperature and rotation, and explains how group huddling maintains body heat for survival in cold. The distractors fail because B incorrectly links to scaring sharks without evidence, C reverses cause and effect, and D denies mention of cold despite the stimulus. To master this, look for evidence in comparisons like heat loss alone versus huddled. Also, identify the specific benefit like staying warm and explain the connection: rotating shares warmth evenly, reducing freezing deaths and aiding winter survival.

Question 17

When lions approach, a baby elephant is surrounded by mother and aunts; lions give up. How does the group help?

  1. Adults block the lions from reaching the calf, so the baby is protected and survives. (correct answer)
  2. The group helps the calf by teaching it to hunt zebras faster than lions.
  3. The lions give up because the calf is stronger when it is alone.
  4. Elephants stay together mainly to play, not to protect young from predators.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. For elephants facing lions, the specific benefit is caring for young through protection, as adults surround the calf, blocking lions and causing them to give up. The correct answer, A, works because it identifies the protection of young benefit, uses evidence from the surrounding behavior and lions' retreat, and explains how group defense keeps the baby safe for survival. The distractors fail because B shifts to teaching hunting without evidence, C incorrectly credits the calf's strength alone, and D emphasizes play over survival. To master this, look for evidence in outcomes like predators giving up when facing a group. Also, identify the specific benefit like young care and explain the connection: collective blocking shields vulnerable members, preventing attacks and ensuring offspring survive.

Question 18

Meerkats feed in the open while one stands watch; when it calls, all run to a burrow. How does this help?

  1. The lookout meerkat calls so the group can find more plants to eat. (correct answer)
  2. Meerkats survive because predators are afraid of the lookout's loud voice.
  3. Meerkats stand on high points because they like tall places, not for survival.
  4. The lookout warns of hawks or snakes, so the group escapes to the burrow safely.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes. For meerkats, the specific benefit is protection via shared lookout duty, as one watches for hawks or snakes and calls, allowing the group to escape to a burrow. The correct answer, A, works because it identifies the protection benefit, uses evidence from the lookout's role and group response, and explains how early warnings help avoid predators for survival. The distractors fail because B incorrectly ties calls to food finding without evidence, C attributes survival to predator fear vaguely, and D focuses on non-survival preferences. To master this, look for evidence in behaviors like warnings and escapes compared to no group. Also, identify the specific benefit like protection and explain the connection: shared vigilance spots danger early, enabling quick hiding and reducing predation risk.

Question 19

A school of 500 fish turns at the same time when a shark comes, and most fish escape. How does moving together help fish survive?

  1. Turning together confuses the shark, so it cannot pick one fish easily and many escape. (correct answer)
  2. The shark catches the whole school more easily, so groups do not help survival.
  3. Turning together makes the shark hungrier, so it stops chasing the fish.
  4. Fish turn together only to make shapes, not to avoid being eaten.
Explanation: This question aligns with the skill 3-LS2-1, which involves using evidence to explain how being in a group helps animals survive. In general, groups help animals survive by providing protection from predators, improving hunting success, caring for young, sharing lookout duties, staying warm, or building better homes.
