1. Select the meaning of the underlined word in the following sentence. All volatile liquids should be stored and labeled correctly.

A. Unstable
B. Abnormal
C. Lethal
D. Blended

Correct answer: A

Rationale: In the context of the sentence, 'volatile' means likely to change rapidly and unpredictably or evaporate quickly. When referring to liquids, volatile typically implies that the liquids are unstable and can easily change from liquid to gas. Therefore, the most appropriate meaning of 'volatile' in this sentence is 'unstable.' Choices B, C, and D are incorrect because 'abnormal' and 'lethal' do not capture the essence of rapid change or evaporation associated with volatile liquids, while 'blended' is unrelated to the characteristics of volatile liquids described in the sentence.

2. HPV is likely to involve the ___________.

A. skull and spine
B. mucous membranes
C. kidneys
D. heart

Correct answer: B

Rationale: HPV, which stands for Human Papillomavirus, is a virus that commonly affects the skin and mucous membranes. It primarily targets the genital area but can also infect the mouth and throat through oral-genital contact. Therefore, the most likely involvement of HPV is with the mucous membranes, making option B the correct choice. Choices A, C, and D are incorrect because HPV does not typically affect the skull, spine, kidneys, or heart.

3. It seems like the sun _____ on Saturday.

A. never shines
B. never shone
C. rarely shines
D. sometimes shines

Correct answer: B

Rationale: The correct answer is 'never shone' as the sentence is discussing a past event (Saturday). 'Never shone' is the correct past tense form to describe the sun not shining on a specific day in the past. Choices A, C, and D are incorrect because they do not provide the appropriate past tense form needed in this context. 'Never shines' is present tense, 'rarely shines' implies occasional shining, and 'sometimes shines' suggests occasional shining as well, none of which accurately convey the past event of the sun not shining on Saturday.

4. Select the meaning of the following phrase. 'A system of procedures to follow.'

A. Regimen
B. Regime
C. Testament
D. Treatment

Correct answer: A

Rationale: The correct answer is 'Regimen.' 'Regimen' refers to a prescribed set of procedures or a routine, especially related to health. Choice B, 'Regime,' typically refers to a system of government or a ruling period. Choice C, 'Testament,' means a person's will or a statement of belief. Choice D, 'Treatment,' is a medical care given to a patient.

5. Which word is NOT USED CORRECTLY? It sure isn't going to rain during the next playoff.

A. Ain't
B. During
C. Sure
D. Playoff

Correct answer: A

Rationale: The correct answer is A. 'Ain't' is not grammatically correct in formal writing or speech; it should be 'isn't.' 'Ain't' is considered slang and is not appropriate for formal contexts. The other choices ('During,' 'Sure,' 'Playoff') are used correctly in the sentence.
