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.

Rationale: In this context, 'entrance' is used as a verb meaning to enchant or captivate.

Therefore, the correct answer is 'enchant.'

Correct Answer: B

Rationale: A research paper typically includes a bibliography of sources to document the research conducted. In this case, a research paper on the Great Migration would require a bibliography to cite the sources used. Choices A, C, and D do not typically require a bibliography as they are not research-based and focus more on personal or fictional content.

Correct Answer: C

Rationale: The correct answer is C: 'con-'. The prefix 'con-' means 'with' or 'together,' as in words like 'convene' or 'connect.' Choice A, 'bio-', is a prefix that means 'life' or 'living organisms,' not 'with.' Choice B, 'per-', is a prefix that means 'through' or 'thoroughly,' not 'with.' Choice D, 'trans-', is a prefix that means 'across' or 'beyond,' not 'with.' Therefore, the correct choice that means 'with' is 'con-'.

Correct Answer: D
