Which of the following best explains the meaning of extraneous as it is used in the sentence? The report was filled with extraneous details that had nothing to do with the main findings of the study.

Correct Answer: B

Rationale: The word 'extraneous' means something that is irrelevant or unnecessary to the main topic at hand. In the given sentence, 'extraneous' is used to describe details that are not related to the main findings of the study, indicating that they are unnecessary and irrelevant. Therefore, 'irrelevant' is the correct explanation. Choices 'sophisticated,' 'diligent,' and 'useful' do not convey the concept of being unnecessary or unrelated, making them incorrect in the context of the sentence.

Correct Answer: A

Rationale: In medical terminology, the prefix 'an-' is commonly used to indicate 'without' or 'lack of.' In the word 'anaesthetic,' the prefix 'an-' combined with 'aesthetic' signifies the absence of sensation or feeling. Therefore, based on its meaning in medical usage, the most likely meaning of the prefix 'an-' is 'without.' Choices B, C, and D are incorrect: 'against,' 'away,' and 'before' do not align with the prefix 'an-' as used in medical terms.

Correct Answer: C

Rationale: The prefix 'ante-' is commonly used to refer to something that comes before something else in terms of time, order, or position. In the provided sentence, the antechamber is described as a waiting area 'before' guests were allowed into the main hall. This usage indicates that 'ante-' in this context means 'before.' The other choices are incorrect: 'again' implies repetition, 'good' is unrelated, and 'together' does not fit the context of preceding or coming before something else.

Correct Answer: C

Rationale: This sentence is an example of a simile because it compares 'his ego' to 'the tallest mountain' using the word 'as.' Similes use 'like' or 'as' to create a comparison, which is the case here. A metaphor, on the other hand, does not use 'like' or 'as' but instead states that one thing is another. Hyperbole involves exaggerated statements not meant to be taken literally, while idioms are expressions that have a figurative meaning different from the literal interpretation. Therefore, the correct answer is 'C: Simile.'

Correct Answer: A

Rationale: Option A most effectively revises the introduction by clearly stating that English novelist Mary Shelley had an immeasurable impact on literature and popular culture through her conception of Dr. Frankenstein and the hideous monster he created. It maintains the original idea while improving clarity and coherence. Option B introduces confusion by implying that Dr. Frankenstein created the hideous monster when it was actually Mary Shelley who conceived both characters. Option C lacks the necessary conjunctions to make the sentence flow smoothly. Option D unnecessarily specifies the country of origin for Mary Shelley and does not maintain the focus on her impact on literature and popular culture.
