In the sentence 'The cherry tomatoes in our backyard are finally ready to be picked,' which of the following is the complete subject?

Correct Answer: C

Rationale: The complete subject in a sentence refers to the noun or pronoun that the sentence is about. In this case, the complete subject is 'The cherry tomatoes in our backyard.' It includes all the words that describe the subject and provide more specific information about it. 'Tomatoes' (Choice A) is just a part of the complete subject and not the entire subject. 'Ready to be picked' (Choice B) is a verb phrase, not the subject of the sentence. 'Finally ready' (Choice D) is an adjective phrase, not the subject of the sentence. Therefore, the correct choice is 'The cherry tomatoes in our backyard.'

Correct Answer: B

Rationale: The correct answer is B, 'On the 5:30 train.' This is a sentence fragment because it does not contain a subject and a verb. In this case, 'On the 5:30 train' is a prepositional phrase, not a complete sentence. Choices A, C, and D are complete sentences as they have both a subject and a verb, making them grammatically correct and not sentence fragments.

Correct Answer: A

Rationale: The correct answer is sentence A: 'The guests had a wonderful time at the party.' This sentence uses formal language suitable for most written communication. Choice B uses informal language with the word 'awesome,' which is more casual and conversational. Choice C, 'The partygoers wanted to hang out all night,' while not as informal as choice B, is still less formal than choice A. Choice D, 'The partiers were up for something more,' uses slang ('partiers') and casual language ('up for something more'), making it the least formal option among the choices.

Correct Answer: A

Rationale: The correct answer is A because the phrase 'pretty sure' is a colloquialism, making the sentence less formal. Choice B is incorrect as it is a formal recommendation. Choice C is incorrect as it contains no colloquial expressions. Choice D is incorrect as it is a straightforward statement without colloquial language.

Correct Answer: D

Rationale: The sentence 'However, online students often work entirely from home, which is just one part of what makes online learning different.' provides a contrast and smoothly transitions to a discussion of what makes online learning distinct from traditional classroom settings. Choice A talks about the components of a course but does not transition to a new point. Choice B discusses similarities between online and traditional courses, which does not transition to a new topic. Choice C focuses on interactions with professors but does not transition to a new idea.
