1. Which hormone stimulates milk production in the breasts during lactation?

• A. norepinephrine
• B. antidiuretic hormone
• C. prolactin
• D. oxytocin

Correct answer: C

Rationale: During lactation, the hormone responsible for stimulating milk production in the breasts is 'prolactin.' Prolactin plays a crucial role in initiating and maintaining lactation by promoting the development of alveoli in the mammary glands and stimulating milk synthesis. While oxytocin is involved in the ejection of milk from the breasts, it is prolactin that primarily governs milk production. Norepinephrine is not directly involved in milk production, and antidiuretic hormone primarily regulates water balance and blood pressure, not milk production.

2. To cauterize a wound is to ___________.

• A. soothe it
• B. cover it
• C. stitch it
• D. burn it

Correct answer: D

Rationale: To cauterize a wound is to use heat or a chemical to burn the wound in order to stop bleeding and prevent infection. This process helps seal off blood vessels and close the wound by burning the affected tissue. Choice A, 'soothe it,' is incorrect because cauterization involves burning the wound, which is a controlled way of treating it, not soothing it. Choice B, 'cover it,' is incorrect as cauterization involves a more aggressive approach than just covering the wound. Choice C, 'stitch it,' is incorrect as it refers to using sutures to close a wound, which is different from cauterization that involves burning the wound to seal it.

3. What does 'Fatal' mean?

• A. Resulting in injury
• B. Resulting in death
• C. Dangerous
• D. Treatable

Correct answer: B

Rationale: The correct answer is B: 'Resulting in death.' The term 'Fatal' specifically means resulting in death. Choices A, C, and D are incorrect because 'Fatal' does not refer to resulting in injury, being dangerous, or being treatable.

4. Which hormone is produced by the thyroid gland?

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

Correct answer: B

Rationale: Thyroxine is the hormone produced by the thyroid gland. It plays a crucial role in regulating metabolism, heart rate, and growth. Insulin is produced by the pancreas to regulate blood sugar levels, not by the thyroid gland. Glucagon is also produced by the pancreas and helps increase blood sugar levels. Cortisol is produced by the adrenal glands and is involved in stress response and metabolism, not by the thyroid gland.

5. Which of the following words or phrases fits best in the sentence below? Derek insists on working out daily ___________ his time is limited.

• A. despite
• B. due to
• C. even if
• D. whereas

Correct answer: A

Rationale: In the sentence, the word 'despite' is the best fit to convey the meaning that Derek insists on working out daily regardless of the limitation of his time. 'Despite' is used to show contrast or defiance against a situation or condition, making it the most suitable choice among the options provided. Choice B, 'due to,' would imply that Derek is working out daily because his time is limited, which is not the intended meaning of the sentence. Choice C, 'even if,' suggests a conditional scenario which does not align with the context of Derek's daily routine. Choice D, 'whereas,' introduces a comparison between two contrasting clauses, which does not fit the sentence where the focus is on Derek's persistence in working out despite limited time.
