Correct Answer: C

Rationale: The semicolon after "that" is used incorrectly; a comma should be used instead. Semicolons are typically used to join two independent clauses without a conjunction. In this sentence, the phrase "just like that" is not an independent clause, so a comma is more appropriate for separating it from the rest of the sentence. Choices A, B, and D all use commas correctly within the sentence.

Correct Answer: C

Rationale: Choice C is the correct answer because it properly uses quotation marks to indicate a direct quote within the sentence ('My history presentation was great!'). Choices A, B, and D contain direct quotes but fail to use quotation marks, making them incorrect. In choice A, the direct question 'How was your day?' should be enclosed in quotation marks. In choice B, the direct quote 'It was awesome.' should also be enclosed in quotation marks. In choice D, the direct statement 'That's wonderful!' should be enclosed in quotation marks.

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 A - 'Went to the store yesterday.' This sentence is a fragment because it lacks a subject. A complete sentence should have both a subject and a verb. Choice B, C, and D are all complete sentences as they have both a subject ('She') and a verb ('went'). Therefore, they are not fragments.

Correct Answer: B

Rationale: The correct answer is 'Supra-' as it means 'above.' 'Dys-' denotes 'bad' or 'difficult,' 'Intra-' means 'within,' and 'Sub-' indicates 'below' or 'under.' Therefore, choices A, C, and D are incorrect in the context of the question.
