1. Which hormone is involved in regulating the sleep-wake cycle?

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

Correct answer: B

Rationale: The correct answer is B: Melatonin. Melatonin, produced by the pineal gland, is the hormone involved in regulating the sleep-wake cycle. It plays a crucial role in signaling the body that it is time to sleep and is influenced by light exposure. Melatonin levels typically rise in the evening, promoting sleep, and decrease in the morning, helping in waking up. Choice A, Insulin, is involved in regulating blood sugar levels, not the sleep-wake cycle. Choice C, Cortisol, is a stress hormone that helps regulate metabolism and immune response but is not primarily involved in the sleep-wake cycle. Choice D, Thyroxine, is a hormone produced by the thyroid gland that regulates metabolism, growth, and development, but it is not directly involved in regulating the sleep-wake cycle.

2. Which word means TO THINK ABOUT SOMETHING BEFORE MAKING A DECISION?

• A. Imply
• B. Transgress
• C. Allay
• D. Ruminate

Correct answer: D

Rationale: The word 'ruminate' means to think deeply about something before making a decision. It specifically implies reflecting or pondering carefully on a matter, indicating a thoughtful consideration process. Choices A, B, and C are incorrect. 'Imply' means to suggest indirectly, 'transgress' means to go beyond limits or boundaries, and 'allay' means to diminish or put to rest feelings of fear or suspicion. These words do not convey the concept of thoughtful contemplation before making a decision.

3. What is the CORRECT CONTRACTION for 'They are'?

• A. Their
• B. They're
• C. The're
• D. No contraction used

Correct answer: B

Rationale: The correct contraction for 'They are' is 'They're.' 'Their' is a possessive pronoun indicating ownership, not a contraction. 'The're' is not a valid contraction. 'No contraction used' is incorrect as there is a contraction for 'They are,' which is 'They're.'

4. What word is best to substitute for the underlined words in the following sentence? Could Kendra manage to carry both Kendra’s books and yours?

• A. her
• B. his
• C. she's
• D. hers

Correct answer: D

Rationale: In the sentence, 'Could Kendra manage to carry both Kendra’s books and yours?', the possessive pronoun 'hers' is the best substitution for the underlined words. The use of 'hers' correctly indicates possession by Kendra, making it the most appropriate word choice to replace 'Kendra’s books'. Choice A, 'her', is incorrect as it refers to the possessive form of a singular female noun, not being possessive of 'Kendra'. Choice B, 'his', is incorrect as it is the possessive pronoun for a singular male noun, not suitable for replacing 'Kendra’s books'. Choice C, 'she's', is incorrect as it is a contraction for 'she is', which does not fit the possessive context needed in the sentence.

5. If a parent changes their baby 6 times a day, how many diapers will be needed in a year?

• A. 2190 diapers
• B. 2100 diapers
• C. 2160 diapers
• D. 2140 diapers

Correct answer: A

Rationale: To calculate the number of diapers needed in a year with 6 diaper changes per day, multiply the daily diaper changes (6) by the days in a year (365): 6 x 365 = 2190 diapers required. This calculation ensures an ample supply of diapers for maintaining the infant's hygiene and comfort. The other choices are incorrect because they do not accurately account for the number of diaper changes per day multiplied by the days in a year. Choice B (2100 diapers) is too low, while choices C (2160 diapers) and D (2140 diapers) are too high based on the calculation. Understanding the frequency and quantity of diaper changes is crucial for supporting the infant's health and well-being. Therefore, the correct answer is 2190 diapers.
