1. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

2. Select the meaning of the word 'vital' in the sentence: 'It is vital for the victim of a serious accident to receive medical attention immediately.'

A. recommended
B. discouraged
C. essential
D. sufficient

Correct answer: C

Rationale: In this context, 'vital' means absolutely necessary or essential, indicating that receiving medical attention immediately is crucial for the victim's well-being. Choice A, 'recommended,' suggests a level of advisability rather than necessity. Choice B, 'discouraged,' is the opposite of the meaning conveyed by 'vital.' Choice D, 'sufficient,' implies having enough of something, which is not the intended meaning in the given sentence.

3. Which sentence contains a subject-verb agreement error?

A. The group of students is very smart
B. The team of players is winning
C. The list of items is on the table
D. The pile of books is heavy

Correct answer: B

Rationale: The correct answer is 'B: The team of players is winning.' The error in this sentence is a subject-verb agreement issue. 'Team' is a singular noun, so it should take a singular verb 'is' instead of 'are.' The subject-verb agreement rule states that singular subjects should be paired with singular verbs, while plural subjects should be paired with plural verbs. Choices A, C, and D all demonstrate correct subject-verb agreement as they correctly match singular subjects ('group,' 'list,' 'pile') with singular verbs ('is,' 'is,' 'is').

4. Which word is a synonym for ASSURED?

A. Confirmed the truth of
B. Sympathized with
C. Denied the truth of
D. Made known to

Correct answer: A

Rationale: The correct answer is 'Confirmed the truth of' because 'assured' means to make certain or confident. To confirm the truth of something is to provide certainty, which aligns with the meaning of 'assured.' Choice B, 'Sympathized with,' is incorrect as it means to express compassion or understanding, which is not synonymous with 'assured.' Choice C, 'Denied the truth of,' is incorrect as it means to reject or contradict the truth, which is the opposite of 'assured.' Choice D, 'Made known to,' is incorrect as it refers to revealing or informing, which is not synonymous with 'assured.'

5. Choose the meaning of the word 'sanctioned' in the following sentence: 'The professor sanctioned our field trip to the chemistry lab.'

A. Organized
B. Deterred
C. Neglected
D. Authorized

Correct answer: D

Rationale: In this context, the word 'sanctioned' means to authorize or approve. The sentence indicates that the professor gave permission for the field trip to the chemistry lab, which aligns with the meaning of 'authorized.' Choices A, B, and C are incorrect. 'Organized' does not fit the context as the sentence is about granting approval, not arranging. 'Deterred' means to discourage, which is the opposite of what the professor did. 'Neglected' means failed to care for or pay attention to, which is unrelated to the professor approving the field trip.
