1. What is the correct pronoun to complete the sentence?

• A. Her
• B. Hers
• C. Best
• D. More greatest

Correct answer: A

Rationale: The word 'her' is the correct choice because it serves as the object of the preposition 'at.' In this sentence, 'looked at' requires an object pronoun, making 'her' the appropriate choice. Option B, 'Hers,' indicates possession, which is not needed in this context. Options C and D are not pronouns and do not fit grammatically in the sentence.

2. Which gland produces hormones that regulate sleep?

• A. Thyroid gland
• B. Pineal gland
• C. Adrenal gland
• D. Pituitary gland

Correct answer: B

Rationale: The pineal gland secretes melatonin, a hormone that plays a crucial role in regulating the sleep-wake cycle. Melatonin production is influenced by exposure to light, with levels increasing in the evening to promote sleep and decreasing in the morning to signal wakefulness. Choices A, C, and D are incorrect because the thyroid gland primarily regulates metabolism, the adrenal gland produces hormones like adrenaline and cortisol related to stress response, and the pituitary gland controls various functions by releasing different hormones but not specifically related to regulating sleep.

3. If the outside temperature is currently 22 degrees on the Celsius scale, what is the approximate temperature on the Fahrenheit scale?

• A. 56°F
• B. 62°F
• C. 66.5°F
• D. 71.6°F

Correct answer: D

Rationale: To convert Celsius to Fahrenheit, you can use the formula: F = (C x 1.8) + 32. Substituting C = 22 into the formula gives: F = (22 x 1.8) + 32 = 39.6 + 32 = 71.6°F. Therefore, the approximate temperature on the Fahrenheit scale when it is 22 degrees Celsius is 71.6°F. Choices A, B, and C are incorrect because they do not match the correct conversion result. Choice A, 56°F, is lower than the correct conversion. Choice B, 62°F, is also lower than the correct conversion. Choice C, 66.5°F, is not a whole number and does not match the precise conversion of 71.6°F. Thus, the correct answer is 71.6°F.

4. Select the word that makes the following sentence grammatically correct. The committee finished _______ report in time for the annual review.

• A. its
• B. their
• C. it's
• D. they're

Correct answer: A

Rationale: In this sentence, "committee" is a singular noun, so the correct pronoun to use is "its." The possessive pronoun "its" indicates that the committee is taking ownership of the report it finished. Choice B, "their," is incorrect as it is a plural pronoun and does not agree with the singular noun "committee." Choices C and D are also incorrect as they represent contractions ("it's" for "it is" and "they're" for "they are"), which do not fit in the context of showing possession of the report by the committee.

5. What is the primary function of the heart?

• A. To filter blood
• B. To transport oxygen and nutrients
• C. To remove waste
• D. To regulate temperature

Correct answer: B

Rationale: The primary function of the heart is to pump oxygenated blood and nutrients throughout the body, supplying cells with vital substances. Choice A is incorrect as the kidneys are responsible for filtering blood. Choice C is incorrect as waste removal is primarily handled by organs like the kidneys and liver. Choice D is incorrect as regulating body temperature is mainly controlled by mechanisms such as sweating and shivering, not the heart.
