Step-by-step explanation:
16. The correct answer is "more than" because the flight was delayed for a longer duration than three hours. "Within" and "still" do not make sense in this context, and "now that" does not convey the duration of the delay.
17. The correct answer is "decrease" because it accurately describes a decrease in sales. "Decreasingly" is not a word, "to decrease" is not an adjective, and "decreased" is the past tense form of the verb "decrease."
18. The correct answer is "will have completed" because it describes an action that will be completed in the future. "Completes" is the present tense form of the verb "complete," "has completed" is the past tense form, and "were completing" is the past continuous tense form.
19. The correct answer is "directory" because it refers to a list of information, such as telephone numbers, e-mail addresses, and areas of expertise. "Direct" is an adjective that means "going straight to a place or person without stopping," and "directly" is an adverb that means "in a direct way."
20. The correct answer is "opposite" because it means that the hotel is located across from the Sherwood Central Station. "Across" means "on the other side," "next" means "next to," and "nearby" means "close by."
21. The correct answer is "directly" because it means that the furniture is not exposed to sunlight in a direct way. "Direct" is an adjective that means "going straight to a place or person without stopping," and "direction" is a noun that refers to a specific course or way. "Directory" is a noun that refers to a list of information.
22. The correct answer is "another" because it means "one more," indicating that the factory's completion has been postponed by an additional two weeks. "Several" means "a few," "much" means "a large amount," and "other" means "different or additional."
23. The correct answer is "so that" because it introduces a clause that explains the purpose of relying on e-mail and scheduling software. "Not only" means "not just," "on behalf of" means "for the benefit of," and "while" means "during the same time."
