1. What is the expression 1 in. = 2.54 cm properly called?

• A. Law of Conservation of Units
• B. International Yard
• C. Standard Conversion Factor
• D. Exact Equivalent

Correct answer: D

Rationale: The correct answer is D: Exact Equivalent. The expression 1 inch = 2.54 cm is a direct and precise conversion between inches and centimeters, making it an exact equivalent. It is not related to the Law of Conservation of Units (A) as this principle pertains to the conservation of physical quantities in a system. The International Yard (B) is a unit of measurement, but it is not the term for the given expression. Similarly, while the conversion factor in the expression is standard, it is specifically an exact equivalent and not just a general standard conversion factor (C). Therefore, D is the most appropriate term to describe this specific conversion relationship.

2. The 'fight-or-flight' response is triggered by the hormone released from the:

• A. Thyroid gland
• B. Adrenal glands
• C. Pituitary gland
• D. Pancreas

Correct answer: B

Rationale: The 'fight-or-flight' response is triggered by the release of adrenaline (epinephrine) and norepinephrine from the adrenal glands. These hormones prepare the body to either confront or flee from a perceived threat or stressor. The adrenal glands are crucial in initiating this rapid physiological response. Choices A, C, and D are incorrect because the thyroid gland primarily regulates metabolism and energy levels, the pituitary gland controls other endocrine glands but does not directly trigger the 'fight-or-flight' response, and the pancreas is responsible for regulating blood sugar levels through insulin and glucagon, not for triggering the 'fight-or-flight' response.

3. Select the correct verb to complete the following sentence: I _________ about it for a long time before I decided to major in criminal justice.

• A. think
• B. thank
• C. thinked
• D. thought

Correct answer: D

Rationale: The correct answer is 'thought.' 'Thought' is the correct past tense form of 'think.' In this sentence, 'thought' is used to indicate that the thinking process happened in the past before deciding to major in criminal justice. Choices A, B, and C are incorrect. 'Think' is the present tense form, 'thank' is a different verb with a different meaning, and 'thinked' is not a valid past tense form of 'think.'

4. “His ego was as big as the tallest mountain.” This sentence is an example of which figure of speech?

• A. Hyperbole
• B. Idiom
• C. Simile
• D. Metaphor

Correct answer: C

Rationale: This sentence is an example of a simile because it compares 'his ego' to 'the tallest mountain' using the word 'as.' Similes use 'like' or 'as' to create a comparison, which is the case here. A metaphor, on the other hand, does not use 'like' or 'as' but instead states that one thing is another. Hyperbole involves exaggerated statements not meant to be taken literally, while idioms are expressions that have a figurative meaning different from the literal interpretation. Therefore, the correct answer is 'C: Simile.'

5. Which type of muscle is found in the heart?

• A. Smooth muscle
• B. Cardiac muscle
• C. Skeletal muscle
• D. Voluntary muscle

Correct answer: B

Rationale: The correct answer is 'B: Cardiac muscle.' Cardiac muscle is the specific type of muscle found in the heart. Unlike smooth muscle and skeletal muscle, cardiac muscle is involuntary and contracts rhythmically to pump blood throughout the body, making it essential for the heart's function. Smooth muscle (Choice A) is found in the walls of hollow organs and blood vessels, while skeletal muscle (Choice C) is attached to bones and responsible for movement. Voluntary muscle (Choice D) is another term for skeletal muscle, which is under conscious control.
