Correct Answer: A

Rationale: The correct answer is A. The term 'bibliophile' is derived from the Greek words 'biblio' meaning books and 'phile' meaning lover or enthusiast. Therefore, a 'bibliophile' refers to a person who collects or has a great love of books. Choices B, C, and D are incorrect because they do not accurately reflect the meaning of 'bibliophile.' An index at the back of a book is called a 'bibliography,' a compiled list of different books is a 'catalog,' and a place where books are kept is a 'library,' not a 'bibliophile.'

Correct Answer: A

Rationale: In this sentence, 'who' is the correct relative pronoun to refer to a person, John Smith. 'Who' is used for subjects, while 'whom' is used for objects. 'Which' is used for things or animals, and 'that' can refer to both people and things, but 'who' is the most appropriate choice here as it refers specifically to a person, John Smith, who is the one performing the action of photographing the landscape.

Correct Answer: D

Rationale: The correct answer is 'D: Repeat.' 'Reiterate' means to say something again, making 'repeat' a synonym. 'Refine' means to improve, 'relegate' means to dismiss to an inferior position, and 'regale' means to entertain or amuse, which do not align in meaning with 'reiterate.'

Correct Answer: D

Rationale: The word 'outside' is the adverb in the sentence. An adverb is a word that modifies a verb, adjective, or another adverb. In this sentence, 'outside' modifies the verb 'go' by indicating the location where the action is taking place. Choices A, B, and C are incorrect because 'We' is a pronoun, 'should' is a modal verb, and 'go' is the main verb in the sentence, none of which function as adverbs.

Correct Answer: A

Rationale: The simple subject is the noun or pronoun that the sentence is about. In this sentence, the subject is 'man' because it is the entity performing the action of watching. 'The flustered man' is a noun phrase but not the simple subject as it includes an article and an adjective. 'Watched' is a verb and 'train' is the object of the action, not the subject. Therefore, 'man' is the correct simple subject in this sentence.
