The passage notes that one-third of adults are sleep-deprived and links it to multiple serious health risks.

Read the passage and answer the question. "Camouflage is used by animals to blend into their environment, making them harder to spot by predators or prey. Some animals, like the chameleon, can actively change their color to match their surroundings, while others are born with patterns that already match their typical habitat. Both strategies serve the same fundamental survival purpose." According to the passage, what do active color-changing and fixed natural patterns have in common?

Answer: Both serve the same survival purpose

The passage states both color-changing and fixed patterns serve the same fundamental survival purpose.

Read the passage and answer the question. "Dehydration can impair both physical and mental performance. Even mild dehydration—a body water loss of just one to two percent—can cause fatigue, headaches, and difficulty concentrating. During physical activity or in hot weather, the body can lose water rapidly through sweating, making regular fluid intake especially important." The passage implies that staying hydrated is MOST important when:

Answer: Exercising or exposed to high temperatures

The passage states that fluid loss happens rapidly during physical activity or in hot weather, making hydration especially important then.

It is home to thousands of species of marine life and is listed as a UNESCO World Heritage Site. Rising ocean temperatures and ocean acidification, both linked to climate change, pose serious threats to its survival." What is the main threat to the Great Barrier Reef described in the passage?

Answer: Rising temperatures and ocean acidification from climate change

The passage identifies rising ocean temperatures and ocean acidification, both linked to climate change, as the serious threats.

Read the passage and answer the question. "Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into glucose and oxygen. This process is fundamental to nearly all life on Earth because it forms the base of most food chains and produces the oxygen that most organisms need to breathe." According to the passage, photosynthesis is important to life on Earth PRIMARILY because:

Answer: It creates the base of most food chains and produces breathable oxygen

The passage states photosynthesis forms the base of most food chains and produces oxygen, making it fundamental to nearly all life.

Read the passage and answer the question. "Situational awareness is a critical skill in both military and civilian contexts. It involves perceiving elements in the environment, understanding what those elements mean, and projecting how the situation might change in the future. Soldiers who maintain good situational awareness are better equipped to make fast, effective decisions under pressure." According to the passage, situational awareness includes all of the following EXCEPT:

Answer: Eliminating all potential threats before they occur

The passage defines situational awareness as perceiving, understanding, and projecting—not eliminating threats.

Read the passage and answer the question. "Nuclear energy is produced by splitting heavy atomic nuclei, a process called fission, which releases a large amount of energy. Unlike fossil fuels, nuclear power plants do not emit greenhouse gases during operation. However, the storage and disposal of radioactive waste remains a significant challenge for the industry." What advantage of nuclear energy does the passage identify?

Answer: It does not emit greenhouse gases during operation

The passage states nuclear power plants do not emit greenhouse gases during operation, unlike fossil fuels.

Read the passage and answer the question. "A peninsula is a piece of land that is surrounded by water on three sides but connected to a larger landmass on one side. The word comes from the Latin 'paeninsula,' meaning 'almost island.' Florida, South Korea, and Italy are all well-known examples of peninsulas." What best describes a peninsula based on the passage?

Answer: Land surrounded by water on three sides and connected to a landmass on one

The passage defines a peninsula as land surrounded by water on three sides but connected to a larger landmass on one side.

Read the passage and answer the question. "The immune system is the body's defense network against infection and disease. It consists of a complex network of cells, tissues, and organs that work together to identify and neutralize harmful pathogens such as bacteria, viruses, and fungi. Vaccines strengthen the immune system by training it to recognize specific pathogens before real exposure occurs." According to the passage, how do vaccines help the body?

Answer: They train the immune system to recognize pathogens before real exposure

The passage states vaccines strengthen the immune system by training it to recognize specific pathogens before real exposure occurs.

Read the passage and answer the question. "The speed of sound varies depending on the medium through which it travels. In dry air at 68°F (20°C), sound travels at approximately 767 miles per hour. Sound travels faster in liquids than in gases, and faster still in solids, because particles in denser materials are more tightly packed and can transmit vibrations more quickly." Based on the passage, in which medium does sound travel the FASTEST?

Answer: A solid material

The passage states sound travels faster in liquids than gases, and faster still in solids due to tightly packed particles.

Read the passage and answer the question. "Triage is a process used in emergency medicine and military combat to sort patients by the urgency of their need for treatment.

Patients are typically categorized as immediate, delayed, minimal, or expectant based on the severity of their condition and likelihood of survival." What is the PRIMARY goal of triage according to the passage?

Answer: To do the greatest good for the greatest number when resources are limited

The passage explicitly states the goal of triage is to do the greatest good for the greatest number when resources are limited.

Read the passage and answer the question. "Gravity is the force that attracts two objects with mass toward each other. The greater the mass of the objects and the closer they are together, the stronger the gravitational force between them. Earth's gravity keeps the Moon in orbit and prevents the atmosphere from escaping into space." According to the passage, gravitational force between two objects INCREASES when:

Answer: The objects have greater mass and are closer together

The passage states that greater mass and closer proximity both increase the gravitational force between objects.

Read the passage and answer the question. "Propaganda is information, especially of a biased or misleading nature, used to promote a particular political cause or point of view.
