1. How many electron pairs are shared to form a double covalent bond?

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: B

Rationale: The correct answer is B. In a double covalent bond, two pairs of electrons are shared between two atoms. This sharing of two electron pairs results in a stronger bond compared to a single covalent bond where only one pair of electrons is shared. Choice A is incorrect because a single covalent bond involves the sharing of one pair of electrons. Choices C and D are incorrect as they do not represent the correct number of electron pairs shared in a double covalent bond.

2. Someone who is FRUSTRATED/ANNOYED is?

• A. Exacerbated
• B. Transient
• C. Lithe
• D. Terse

Correct answer: A

Rationale: The word 'exacerbated' means to make a problem, bad situation, or negative feeling worse. If someone is frustrated or annoyed, they are likely feeling worse due to a particular situation or circumstance. Choice B, 'transient,' means temporary or short-lived, which does not directly relate to the feeling of being frustrated or annoyed. Choice C, 'lithe,' means thin, supple, and graceful, which is not synonymous with being frustrated or annoyed. Choice D, 'terse,' means brief and to the point, which is unrelated to the context of feeling frustrated or annoyed.

3. Which hormone is not produced by the pituitary gland?

• A. FSH
• B. TRH
• C. LH
• D. ADH

Correct answer: B

Rationale: Thyrotropin-releasing hormone (TRH) is not produced by the pituitary gland. TRH is actually produced by the hypothalamus and acts on the pituitary gland to stimulate the release of thyroid-stimulating hormone (TSH). On the other hand, FSH (follicle-stimulating hormone), LH (luteinizing hormone), and ADH (antidiuretic hormone) are all hormones directly produced by the pituitary gland.

4. What punctuation is needed in this sentence to make it correct? I will check the supply closet, and you can look in the laundry.

• A. Period
• B. Comma
• C. Colon
• D. Semicolon

Correct answer: B

Rationale: The correct answer is B: 'Comma.' In the sentence, a comma is needed to separate the independent clauses 'I will check the supply closet' and 'you can look in the laundry.' This comma helps to indicate a pause between the two related but separate actions that each person is taking. Choice A (Period) is incorrect because a period would create two separate sentences. Choice C (Colon) is incorrect as a colon is used to introduce a list or explanation. Choice D (Semicolon) is incorrect as a semicolon is used to connect two closely related independent clauses without a coordinating conjunction.

5. What word is best to substitute for the underlined word in the following sentence? Roseanne was sent to the lab to collect Roseanne’s results.

• A. she
• B. their
• C. her
• D. hers

Correct answer: C

Rationale: The correct option to substitute for 'Roseanne’s' is 'her' to maintain correct pronoun-antecedent agreement. In this case, using 'her' makes the sentence grammatically correct and clear by referring back to Roseanne in a proper manner. Choice A, 'she,' is a subject pronoun and does not match the possessive form needed in the sentence. Choice B, 'their,' is plural and does not agree with the singular possessive 'Roseanne’s.' Choice D, 'hers,' is a possessive pronoun but cannot directly replace 'Roseanne’s' in this context; 'her' is the appropriate choice to indicate possession.
