1.

The Correct Answer is (D) — This is a question about idiomatic preposition use. (D) is the correct answer: “across” is a preposition typically used when discussing voyages across the open ocean, so it fits within the context. “Up” might be used to describe a trip that went north along a coastline, but it would not be used to describe a journey across the open ocean, so (A) is incorrect. “Aboard” would be used in a phrase describing the type of vessel taken, not the location of the trip, so (B) is incorrect. “Within” is not typically used with the verb “journey,” so (C) is incorrect.

2.

The Correct Answer is (H) — This question tests your understanding of parts of speech. (H) is the correct answer: “Safely” is an adverb that correctly modifies the verb “to travel”; “extraordinary” is an adjective that correctly modifies the noun “distances.” “Safe” is an adjective, so it cannot modify the verb “to travel”; therefore, (F) and (G) are incorrect. “Extraordinarily” is an adverb, so it cannot modify the noun “distances”; therefore, (J) is incorrect.

3.

The Correct Answer is (B) — This question is about appropriate pronoun use. (B) is the correct answer. The underlined word is the object of the preposition “about”; “them” is the form of the third-person plural pronoun that is used as an object. “They” has to be the subject of the clause it is in, not the object, so (A) is incorrect. “Their” is a possessive pronoun, but the context has nothing for it to be in possession of, so (C) is incorrect. “They’re” is a contraction meaning “they are,” which does not make sense in context, so (D) is incorrect.

4.

The Correct Answer is (G) — This question prompts you to pick the appropriate verb form. (G) is the correct answer; “seem” is the correct form of the verb to use after the helping verb “might.” “Seems” is only used as the third-person singular present tense when there are no helping verbs, so (F) is incorrect. “Seeming” never follows the word “might,” so (H) is incorrect. “Seemed” is in the past tense, but the seeming is occurring in the present; furthermore, “seemed” never follows the word “might,” so (J) is incorrect.

5.

The Correct Answer is (D) — Here you need to use the right combination of adjectives and adverbs when modifying a noun. (D) is the correct answer. “Sophisticated” is an adjective that can modify the noun “stellar,” and “highly” is an adverb that can modify the adjective “sophisticated.” “High” is an adjective, so it cannot modify another adjective; therefore, (A) and (B) are incorrect. “Sophisticatedly” is an adverb that cannot modify a noun, such as “system,” so (C) is incorrect.

6.

The Correct Answer is (J) — This is a grammatical agreement question focused on pronoun agreement. (J) is the correct answer. The underlined word needs to be the subject of the verb “could,” and it is referring to “sailors,” so it must be plural. “They” is both plural and a subject pronoun, so it fits. “Their” is plural, but it is a possessive pronoun, not a subject pronoun, so (F) is incorrect. “Them” is plural, but it is an object pronoun, not a subject pronoun, so (G) is incorrect. “He” is a subject pronoun, but it is singular, so (H) is incorrect.

7.

The Correct Answer is (D) — This question is about comparative adjectives. The correct choice is (D), as “cloudier” is the best way to describe a set of nights when it was harder to see stars. Because “cloudier” means “more cloudy,” “more cloudier” is repetitive, so (A) is incorrect. Both “most cloudy” and “cloudiest” imply that these nights had the absolute most clouds, but the passage only indicates they had more clouds than usual, so (B) and (C) are incorrect.

8.

The Correct Answer is (H) — Your task here is to pick the right verb form for the sentence. (H) is the correct answer. The sentence is using the conditional past perfect, which begins with “would have” and must be completed with the past tense form of the verb—in this case, “included.” None of the other options correctly finish the conditional past perfect, so (F), (G), and (J) are all incorrect.

9.

The Correct Answer is (A) — This is a question about verb forms. The verb needs to agree with the plural noun “we”; it also needs to be in the present tense because the sentence is talking about the modern world. Therefore, (A) is the correct answer. “Have” is plural and present tense, so it fits. “Has” is present tense but singular, so (B) is incorrect. “Having” cannot be used as a verb on its own without an auxiliary verb, so (C) is incorrect. (D) is in the present perfect, which indicates that much of the action happened in the past, so (D) is incorrect.

10.

The Correct Answer is (J) — This question tests your knowledge of idiomatic prepositions following the verb “instructed.” (J) is the correct answer. “Instructed in the art” is a common construction, and since the grandfather is doing the instructing, Mau Piailug is being instructed by him. “Instructed with the art,” “instructed of the art,” and “instructed by the art” are not common constructions, so (F), (G), and (H) are incorrect.

11.

The Correct Answer is (B) — This question is about verb forms. The clause is describing something that happened several decades ago, and there are no helping verbs preceding the main verb, so the verb has to be in the past tense. Consequently, since "Began" is the past tense form of the verb in question, (B) is the correct answer. “Begin” is in the present tense, so (A) is incorrect. “Beginned” is an incorrect form of the verb that is never acceptable, so (C) is incorrect. “Begun” is the past participle of the verb; for this verb, the past participle and the past tense are not identical, so (D) is incorrect.

12.

The Correct Answer is (J) — This question is about pronoun forms; the right answer must agree with the clause’s verb. (J) is the correct answer. In this sentence, the underlined word is the subject of the verb “peopled”; “who” can serve as the subject of a clause. “Whom” is used as an object, not a subject, so (F) is incorrect. “Who’ve is a contraction for “who have,” and in the original context it does not make sense to say “who have first peopled,” since the peopling does not extend into the present; therefore, (G) is incorrect. “Whose” is a possessive pronoun; it cannot serve as the subject of a clause, so (H) is incorrect.

13.

The Correct Answer is (B) — This question tests you on the right preposition to use before the word “accident.” (B) is the correct answer, as the conventional preposition to use before the noun “accident” is “by.” “With,” “to,” and “in” are not conventionally used with the noun “accident,” so (A), (C), and (D) are incorrect.

14.

The Correct Answer is (H) — This question is about pronoun agreement. Specifically, the pronoun needs to refer to the singular noun “art.” (H) is the correct answer; “it” is both singular and used to refer to things that are not alive. “They” and “these” are plural, so (F) and (J) are incorrect. “He” is singular, but it is typically used to refer to a person or an animal, not a broad concept like “art,” so (G) is incorrect.

15.

The Correct Answer is (A) — This is a verb forms question, where the verb needs to agree with the plural noun “instructors.” (A), “teach,” does just that, so it’s the correct answer. “Teaches” and “is teaching” are both singular, so (B) and (D) are incorrect. “Teaching” cannot be used on its own as a main verb, so (C) is incorrect.
