1. How many neutrons does carbon-14 have?

• A. 10
• B. 8
• C. 6
• D. 12

Correct answer: B

Rationale: The correct answer is B: 8. Carbon-14 is an isotope of carbon with 6 protons and 8 neutrons. To determine the number of neutrons in an atom, subtract the atomic number (number of protons) from the mass number. In this case, the mass number of carbon-14 is 14, and the atomic number of carbon is 6. Therefore, 14 (mass number) - 6 (atomic number) = 8 neutrons. Choices A, C, and D are incorrect because they do not reflect the correct number of neutrons in a carbon-14 atom.

2. What is the value of pi (π) to 2 decimal places?

• A. 3.12
• B. 3.14
• C. 3.16
• D. 3.18

Correct answer: B

Rationale: The value of pi (π) up to two decimal places is 3.14. Pi is a mathematical constant representing the ratio of a circle's circumference to its diameter and is commonly approximated as 3.14. Choices A, C, and D are incorrect as they do not match the standard approximation of pi up to two decimal places.

3. Which hormone is released during the body's fight-or-flight response?

• A. Insulin
• B. Adrenaline
• C. Thyroxine
• D. Cortisol

Correct answer: B

Rationale: Adrenaline, also known as epinephrine, is released during the body's fight-or-flight response. This hormone prepares the body for rapid action by increasing heart rate, dilating airways, and redirecting blood flow to essential organs in response to stress or danger. Insulin is not released during the fight-or-flight response; its primary role is to regulate blood sugar levels. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism, and cortisol is released in response to stress to regulate various bodily functions, but adrenaline is the hormone specifically associated with the fight-or-flight response.

4. What does Lateral mean?

• A. Near the midline
• B. Away from the midline
• C. At the top of the body
• D. On the side

Correct answer: D

Rationale: The correct answer is D: 'On the side.' Lateral means situated on the side or away from the midline. Choices A, B, and C are incorrect because lateral specifically refers to a position that is situated away from the midline, not near it, at the top of the body, or on the side.

5. Select the phrase in the sentence that is not used correctly. Until his trip to Puerto Rico, Javier had never seen his ancestral home.

• A. Until his trip
• B. had never
• C. never seen
• D. his ancestral home

Correct answer: C

Rationale: The phrase 'never seen' in the sentence is not used correctly. The correct phrase should be 'never seen,' which is the past participle form of the verb 'see.' In this context, 'seen' is the correct past participle to use with 'had never.' Choice A, 'Until his trip,' is correct as it sets the time frame. Choice B, 'had never,' is also correct as it indicates the past perfect tense. Choice D, 'his ancestral home,' is also used correctly as it refers to the place Javier had never seen before.
