1. The adrenal glands are part of which system?

• A. Immune system
• B. Endocrine system
• C. Lymphatic system
• D. Respiratory system

Correct answer: B

Rationale: The correct answer is B: Endocrine system. The adrenal glands are part of the endocrine system, not the immune, lymphatic, or respiratory system. The endocrine system is responsible for producing and regulating hormones that control various bodily functions. The adrenal glands specifically produce hormones like cortisol and adrenaline, which are critical for the body's response to stress and metabolic processes. The immune system is responsible for defending the body against infections and diseases, the lymphatic system is involved in immunity and fluid balance, and the respiratory system is responsible for gas exchange in the body. Therefore, choices A, C, and D are incorrect in the context of the adrenal glands.

2. From the passage, which of the following statements represents a logical conclusion about the author?

• A. The author loves to attend theatrical productions
• B. The author prefers musical comedies
• C. The author also enjoys concerts and movies
• D. The author finds theater seating comfortable

Correct answer: A

Rationale: The correct answer is A. The passage does not provide any information about the author's preference for musical comedies (choice B), enjoyment of concerts and movies (choice C), or comfort with theater seating (choice D). However, the passage does mention cicadas and their emergence, not providing any details that connect to the author's preferences. Therefore, the only logical conclusion that can be drawn about the author is that they love attending theatrical productions, as suggested by the deep love for attending theater productions.

3. What term describes the phenomenon of two waves canceling each other out when they meet?

• A. Refraction
• B. Diffraction
• C. Destructive interference
• D. Constructive interference

Correct answer: C

Rationale: Destructive interference is the term used to describe the phenomenon when two waves meet and their amplitudes are such that they cancel each other out, resulting in a wave with a smaller amplitude or no wave at all. This cancellation effect occurs due to the waves being out of phase. This is in contrast to constructive interference, where two waves combine to produce a wave with a larger amplitude. Refraction is the bending of waves as they pass through different mediums, such as light passing through glass, while diffraction is the bending of waves around obstacles or through openings. In this case, the concept described in the question specifically aligns with destructive interference, making it the correct answer.

4. Long bones are one of the five major types of bones in the human body. All of the following bones are long bones, EXCEPT

• A. Thighs
• B. Forearms
• C. Ankles
• D. Fingers

Correct answer: D

Rationale: Long bones are one of the five major types of bones in the human body, characterized by their elongated shape. Thighs, forearms, and ankles are examples of long bones as they are longer than they are wide and have a tubular structure, aiding in support and movement. Fingers, however, are categorized as short bones due to their small size and shape. Short bones like fingers are essential for providing dexterity and precise movements rather than supporting weight or acting as levers for movement. Therefore, the correct answer is D, Fingers, as they are not classified as long bones.

5. Robert is planning to drive 1,800 miles on a cross-country trip. If his car gets 30 miles per gallon and his tank holds 12 gallons of gas, how many tanks of gas will he need to complete the trip?

• A. 3 tanks
• B. 5 tanks
• C. 30 tanks
• D. 60 tanks

Correct answer: B

Rationale: To find out how many tanks of gas Robert needs for the 1,800-mile trip, first, we calculate the distance his car can travel on a full tank: 30 miles per gallon × 12 gallons = 360 miles per tank. Next, divide the total trip distance by the distance per tank: 1,800 miles ÷ 360 miles per tank = 5 tanks. Therefore, Robert will need 5 tanks of gas to complete the cross-country trip. Choices A, C, and D are incorrect as they do not accurately calculate the number of tanks needed based on the given information.
