Read each passage carefully. Then, identify the central idea and the supporting details that prove it.
Passage 1: The Importance of Exercise
Regular exercise is crucial for maintaining good health. It strengthens your heart and lungs, making them more efficient at pumping blood and oxygen throughout your body. Exercise also helps control weight by burning calories and building muscle mass. Furthermore, physical activity can improve your mood and reduce stress, as it releases endorphins, which have mood-boosting effects. Finally, exercising regularly can boost your immune system, helping your body fight off illnesses more effectively.
1. What is the central idea of Passage 1?
2. List three supporting details from the passage that prove the central idea.
Passage 2: The Adaptations of Desert Animals
Desert animals have developed incredible adaptations to survive in harsh, arid environments. Many are nocturnal, meaning they are active at night when temperatures are cooler, avoiding the scorching daytime heat. Some animals, like the fennec fox, have large ears that help dissipate body heat. Others, such as the camel, can store water in their humps and have thick fur to protect against both sun and cold desert nights. Many desert rodents get all the water they need from the seeds they eat, rarely needing to drink.
3. Which of the following best states the central idea of Passage 2?
Desert animals are all nocturnal.
Camels store water in their humps.
Desert animals have unique adaptations to survive.
Fennec foxes have large ears.
4. Which detail from Passage 2 supports the idea that desert animals avoid heat?
Passage 3: The Ocean's Deepest Zone
The hadal zone is the deepest part of the ocean, found in trenches and canyons. Life here is extremely challenging due to immense pressure, complete darkness, and near-freezing temperatures. However, scientists have discovered unique creatures thriving in this extreme environment. For instance, hadal snailfish have adapted to the high pressure with special proteins in their bodies. Some organisms use chemosynthesis, creating food from chemicals instead of sunlight. These discoveries show that life can adapt to even the most forbidding conditions on Earth.
5. True or False: The central idea of Passage 3 is that the hadal zone is completely devoid of life.
True
False
6. Fill in the blank: One supporting detail for the idea that life thrives in the hadal zone is that .
