1. Select the word or phrase that makes the following sentence grammatically correct: 'Why did we ____ try so hard?'

• A. has to
• B. haven't
• C. had to
• D. have to

Correct answer: D

Rationale: 'Have to' is the correct choice as it fits the sentence structure. The sentence is in the past tense ('did we') and requires the infinitive form 'have to' to express the idea of necessity or obligation in the past. 'Has to' (Choice A) is incorrect as it is present tense, 'haven't' (Choice B) is a negative form and does not make sense in this context, and 'had to' (Choice C) would imply a past obligation that has already been fulfilled, which is not the intended meaning here.

2. What are bases or alkaline solutions known as?

• A. Hydrogen acceptors
• B. Solutions of low pH
• C. Hydrogen donors
• D. Amphoteric

Correct answer: A

Rationale: Bases or alkaline solutions are known as 'hydrogen acceptors.' They accept protons (H+) in chemical reactions, as opposed to acids that donate protons. This property allows bases to neutralize acids and form salts. Choice B, 'Solutions of low pH,' is incorrect because bases have high pH values, not low. Choice C, 'Hydrogen donors,' is incorrect as bases do not donate protons but accept them. Choice D, 'Amphoteric,' refers to substances that can act as both acids and bases, which is not the definition of bases. Therefore, the correct answer is A.

3. Which word correctly completes the sentence? 'The men and women of the graduating class ___ their caps in the air.'

• A. Thorough
• B. Through
• C. Threw
• D. Throwing

Correct answer: C

Rationale: The correct answer is 'C: Threw.' In this sentence, we need the past tense form of the verb 'throw' to show the action that occurred. Therefore, 'threw' is the correct choice. 'Thorough' (choice A) means complete or exhaustive, which doesn't fit the context of the sentence. 'Through' (choice B) is a preposition or an adverb, not the correct verb form. 'Throwing' (choice D) is the present participle form and does not match the past tense needed in the sentence.

4. Select the word or phrase that makes this sentence grammatically correct: 'Felix was pleased ____ the progress he had made in his program.'

• A. among
• B. with
• C. regards
• D. besides

Correct answer: B

Rationale: The correct preposition to use in this context is 'with.' 'Felix was pleased with the progress he had made in his program' indicates that Felix's satisfaction is directly related to the progress he achieved. 'Among' is incorrect as it implies being part of a group, 'regards' is not a suitable preposition in this context, and 'besides' does not convey the intended meaning of satisfaction with the progress.

5. Which statement would not be inferred by the reader in the passage about MRSA?

• A. Hospitals may soon limit the spread of infection with a new textile.
• B. MRSA begins by infecting the skin.
• C. You are most likely to contract MRSA in a crowded location.
• D. Used clothing stores may harbor MRSA.

Correct answer: D

Rationale: The correct answer is D: 'Used clothing stores may harbor MRSA.' This statement is not supported by the passage. The passage mentions the spread of MRSA in hospitals, gyms, locker rooms, swimming pools, and other settings with frequent human contact, but it does not mention used clothing stores as a common location for MRSA. Therefore, it is an unlikely inference. Choice A is supported by the passage as it discusses the development of a new textile to halt the spread of hospital-associated MRSA. Choice B is also supported as the passage mentions MRSA as a skin infection. Choice C is supported by the passage as it states that MRSA has become ubiquitous in settings with frequent human contact.
