Correct Answer: A

Rationale: The sentence 'Neither of the cars is parked on the street' is incorrect in terms of subject-verb agreement. The subject 'Neither' is singular, so the verb should also be singular, which should be 'is' instead of 'are.' The correct sentence should be 'Neither of the cars is parked on the street.' Choices B, C, and D demonstrate correct subject-verb agreement. In choice B, 'Both' is plural and agrees with the plural verb 'are.' In choice C, 'Any' is singular and agrees with the singular verb 'are.' In choice D, 'Each' is singular and agrees with the singular verb 'is.'

Correct Answer: C

Rationale: The key context clue essential to decipher the word 'ubiquitous' is the word 'now.' By comparing the rarity of automobiles a hundred years ago to their ubiquity now, the student can infer that 'ubiquitous' means something that is commonplace or found everywhere. Choice A ('Ago') refers to the past and does not provide information about the current state of cars. Choice B ('Cars') only contrasts rare and ubiquitous without indicating the change over time. Choice D ('Rare') simply contrasts with 'ubiquitous' without showing the transition from rarity to ubiquity.

Correct Answer: D

Rationale: The correct answer is D, 'Exclamation mark.' Exclamation marks are used to express strong emotions such as excitement, surprise, or urgency. They indicate a heightened level of emotion in a sentence. Periods (A) are used to indicate the end of a statement, commas (B) are used to separate elements in a sentence, and question marks (C) are used to indicate questions or uncertainty. In this context, the use of an exclamation mark is the most appropriate choice to convey a strong feeling or emotion.

Correct Answer: A

Rationale: Option A uses correct punctuation by correctly utilizing the semicolon to separate two closely related independent clauses. This punctuation choice effectively conveys the relationship between the two ideas presented in the sentence. Choice B is incorrect because it uses a comma without a coordinating conjunction to join two independent clauses. Choice C is incorrect as it lacks the coordinating conjunction 'and' after the comma to connect the two independent clauses. Choice D is incorrect because it lacks any punctuation or conjunction to properly separate the two independent clauses, leading to a run-on sentence.

Correct Answer: B

Rationale: The correct answer is 'Bibliophile.' The term 'biblio-' is an affix that refers to books, and '-phile' denotes love or attraction. Therefore, 'bibliophile' specifically means a person who loves or collects books. Choice A, 'Logophile,' while containing the '-phile' suffix denoting love, relates to words instead of books. Choices C and D, 'Discophile' and 'Audiophile,' are incorrect as they respectively pertain to music records and sound systems, not books.
