1. Which of the following is not a component of the central nervous system?

• A. Brain
• B. Heart
• C. Retina
• D. Spinal cord

Correct answer: B

Rationale: The central nervous system comprises the brain and spinal cord, responsible for processing and transmitting information. The retina, though part of the eye, is an extension of the central nervous system. However, the heart is part of the circulatory system, responsible for pumping blood throughout the body. Therefore, the correct answer is the heart as it is not a component of the central nervous system.

2. Which phrase correctly completes the sentence? 'During the fight, I was hit on ___.'

• A. Head
• B. On head
• C. A head
• D. The head

Correct answer: A

Rationale: The correct answer is 'A: Head.' The phrase 'on the head' is a prepositional phrase indicating where the person was hit. 'Head' is the correct noun to complete the sentence. Choices B, C, and D are incorrect because they either add unnecessary articles ('a' or 'the') or incorrectly use the preposition 'on' before 'head.' The correct structure is 'hit on the head,' without any additional articles.

3. Which two bases are purines?

• A. Adenine (A)
• B. Cytosine (C)
• C. Thymine (T)
• D. Guanine (G)

Correct answer: A

Rationale: Adenine (A) and guanine (G) are the two bases that are purines. Purines are characterized by a double-ring structure containing two carbon rings, distinguishing them from pyrimidines. Adenine and guanine are purines because they possess this unique double-ring structure. Therefore, choices A and D, adenine and guanine, respectively, are the correct answers. Choices B and C, cytosine and thymine, are pyrimidines and do not exhibit the double-ring structure characteristic of purines.

4. Another word for PRECAUTION is?

• A. Routine procedure
• B. Preventive measure
• C. Habit
• D. Safeguard

Correct answer: B

Rationale: Another word for PRECAUTION is a preventive measure because both terms refer to actions taken in advance to prevent something untoward from happening. They are proactive steps aimed at avoiding potential risks or harm. While a routine procedure and habit may involve general practices, a preventive measure specifically denotes a proactive step taken to avert potential dangers or issues. 'Routine procedure' is incorrect as it does not necessarily imply preventive action. 'Habit' is incorrect as it refers to repeated behaviors rather than proactive steps. 'Safeguard' is incorrect as it generally means protection rather than a proactive preventive action.

5. How many pints are in 56 ounces?

• A. 3.5 pints
• B. 4 pints
• C. 3 pints
• D. 4.5 pints

Correct answer: A

Rationale: To convert ounces to pints, you need to know that 1 pint is equivalent to 16 ounces. Therefore, to find how many pints are in 56 ounces, you divide 56 by 16, which equals 3.5 pints. Hence, the correct answer is 3.5 pints. Choice B, 4 pints, is incorrect because it doesn't account for the conversion factor of 16 ounces per pint. Choice C, 3 pints, is incorrect as it is less than the actual conversion result. Choice D, 4.5 pints, is incorrect as it overestimates the number of pints in 56 ounces.
