What type of sentence is the sentence above?

Correct Answer: B

Rationale: The sentence above is a complex sentence because it contains an independent clause 'You are a helpful assistant' and a dependent clause 'What type of sentence is the sentence above?'. A complex sentence is formed by joining an independent clause with one or more dependent clauses. In this case, the dependent clause 'What type of sentence is the sentence above?' cannot stand alone as a complete sentence. Choices A, C, and D are incorrect because the sentence does not contain multiple independent clauses (compound) or a combination of independent and dependent clauses (compound-complex).

Correct Answer: D

Rationale: The purpose of the parentheses in the sentence is to set off useful information that does not fit directly into the flow of the sentence. Parentheses are commonly used to provide additional details, explanations, or examples that are helpful but not essential to the main point of the sentence. In this case, the information about the Austro-Hungarian Empire is presented in parentheses to offer context but is not crucial to the main idea being communicated. Choices A, B, and C are incorrect as they do not accurately describe the function of parentheses in this context.

Correct Answer: B

Rationale: The point of view indicated by the underlined words in the sentence demonstrates a transition from second-person ("you") to first-person ("I"). The correct answer is B because the speaker shifts from addressing someone else (second-person) to talking about themselves (first-person). Choice A is incorrect because third-person is not present in the sentence. Choice C is incorrect because the order of point of view shift is reversed. Choice D is incorrect as it incorrectly identifies the sequence of point of view change.

Correct Answer: B

Rationale: The conjunction 'and' is used to connect the two independent clauses in the most effective and grammatically correct way. This choice maintains the clarity of the sentence and the relationship between the two ideas. Choice A is incorrect as it lacks the necessary conjunction to properly connect the two independent clauses. Choice C is incorrect as it misses the subject 'they' before 'were determined.' Choice D is incorrect as it lacks the necessary coordinating conjunction 'and' before 'were determined,' resulting in a run-on sentence.

Correct Answer: A

Rationale: The word 'obsequious' means excessively submissive or eager to please, often to the point of showing deference. In this context, 'showing deference' best captures the meaning, indicating respect or submission rather than being poorly dressed, reserved, or aggressive. 'Poorly dressed' (B) is unrelated to the meaning of obsequious. 'Reserved' (C) suggests a different behavior that is opposite to being obsequious. 'Aggressive' (D) is the opposite of obsequious and does not fit the context of the sentence.
