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: C

Rationale: The given sentence, "Because it was raining, the match was canceled," is a complex sentence. It consists of one independent clause ('the match was canceled') and one dependent clause ('Because it was raining'). A simple sentence contains one independent clause with no dependent clauses. A compound sentence has two or more independent clauses but no dependent clauses. A compound-complex sentence has two or more independent clauses and at least one dependent clause, which is not the case here. Therefore, the correct classification for this sentence is a complex sentence.

Correct Answer: B

Rationale: The correct answer is "But". A conjunction is a word that connects words, phrases, or clauses. In this case, "But" is a conjunction used to indicate a contrast or opposition between ideas. The other choices, "Quickly", "Very", and "Apple", are not conjunctions. "Quickly" is an adverb, "Very" is an adverb, and "Apple" is a noun, none of which serve the function of connecting words, phrases, or clauses as conjunctions do.

Correct Answer: B

Rationale: A complex sentence consists of one independent clause and at least one dependent clause. In sentence B, 'Because my tea was cold' is the dependent clause, indicating that it cannot stand alone as a complete sentence. Choices A, C, and D do not contain a dependent clause along with an independent clause, making them incorrect. Choice A is a compound sentence with two independent clauses joined by a coordinating conjunction. Choice C is a compound sentence with a series of independent clauses, but lacks a dependent clause. Choice D is a compound-complex sentence with two independent clauses and a dependent clause.

Correct Answer: D

Rationale: The correct answer is D, 'chocolate cookies and vanilla cupcakes.' In this sentence, the friendly baker is the subject, 'offered' is the verb, and 'chocolate cookies and vanilla cupcakes' receive the action of the verb, making them the direct object. Choices A, B, and C do not directly receive the action of the verb 'offered,' so they are not the direct object. Choice A is the verb phrase, choice B is a prepositional phrase, and choice C is the subject of the sentence.
