1. Which molecule is responsible for storing and providing a quick source of energy during short bursts of intense physical activity, such as weightlifting or sprinting?

• A. ATP (Adenosine Triphosphate)
• B. Glucose
• C. Myoglobin
• D. Lactic Acid

Correct answer: A

Rationale: ATP (Adenosine Triphosphate) is the molecule responsible for storing and providing a quick source of energy during short bursts of intense physical activity like weightlifting or sprinting. ATP is broken down to release energy rapidly when muscles need quick, intense efforts. Glucose is a source of energy but must be converted into ATP before it can be used by muscles. Myoglobin is a protein that stores oxygen in muscle cells and does not directly provide energy. Lactic acid is produced during intense exercise but is not the primary molecule responsible for providing quick energy during short bursts of intense physical activities.

2. Which of the following statements demonstrates a negative correlation between two variables?

• A. People who play baseball more tend to have more hits
• B. Shorter people tend to weigh less than taller people
• C. Tennis balls that are older tend to have less bounce
• D. Cars that are older tend to have higher mileage

Correct answer: C

Rationale: The correct answer is C. This statement demonstrates a negative correlation between two variables as it indicates that as tennis balls age, their bounce tends to decrease. In a negative correlation, as one variable increases, the other tends to decrease. Choices A, B, and D do not illustrate a negative correlation. Choice A describes a positive correlation, as playing baseball more is associated with having more hits. Choice B does not show a correlation but a general observation. Choice D also does not demonstrate a correlation; it simply states that older cars tend to have higher mileage, without implying a relationship between age and mileage.

3. What is the area of a triangle with a base of 10 cm and a height of 7 cm?

• A. 70 cm²
• B. 35 cm²
• C. 140 cm²
• D. 100 cm²

Correct answer: B

Rationale: To find the area of a triangle, you use the formula A = 1/2 × base × height. Substituting the given values: A = 1/2 × 10 cm × 7 cm = 35 cm². Therefore, the correct answer is B. Choice A (70 cm²) is incorrect as it seems to be the product of the base and height rather than the area formula. Choice C (140 cm²) is incorrect as it appears to be twice the correct answer, possibly a result of a miscalculation. Choice D (100 cm²) is incorrect as it does not reflect the correct calculation based on the given base and height values.

4. The style of this passage is most like that found in a(n)

• A. tourist guidebook
• B. health textbook
• C. encyclopedia
• D. friendly letter

Correct answer: B

Rationale: The style of the given passage is most similar to that found in a health textbook. The author presents facts and details in a structured bulleted list format, focusing on providing tips and information about eating calcium-rich foods. This style is commonly used in educational materials related to health and nutrition, making choice B the most appropriate among the options provided. Choice A, a tourist guidebook, is incorrect as the passage does not aim to guide or provide information about touristic locations. Choice C, an encyclopedia, is also incorrect as an encyclopedia typically provides comprehensive and in-depth information on various topics, which is not reflected in the passage. Choice D, a friendly letter, is incorrect as the passage does not contain personal or conversational elements that are characteristic of a friendly letter.

5. What does the word 'principal' refer to in the following text?

• A. Primary or chief
• B. An acolyte
• C. An individual who provides nurturing
• D. One in a subordinate position

Correct answer: A

Rationale: In this context, the word 'principal' refers to the primary or chief role that Reldresal holds as the principal secretary for private affairs. This term signifies his significant position and authority within the hierarchy. The other choices are incorrect because 'principal' does not mean 'an acolyte' (a follower or assistant), 'an individual who provides nurturing,' or 'one in a subordinate position.'
