Correct Answer: A

Rationale: The correct answer is 'A: She.' In this sentence, 'She' is the correct pronoun to use as the subject since it refers to Nurse Junko, who is one of the individuals performing the action. 'Them' (choice B), 'Me' (choice C), and 'Him' (choice D) are incorrect as they do not match the subject of the sentence, which is Nurse Junko.

Correct Answer: A

Rationale: In this context, 'insidious' means progressing slowly but having harmful effects. This matches the meaning of 'gradual,' making it the correct answer. 'Momentous' means significant or important, which is not the meaning conveyed by 'insidious.' 'Sudden' means abrupt or unexpected, opposite to the slow progression indicated by 'insidious.' 'Innocuous' means harmless, which is the opposite of the harmful effects associated with an insidious disease.

Correct Answer: A

Rationale: The correct answer is A, 'Complex.' The term 'convoluted' is used to describe something that is intricate, complex, or twisted. 'Clever' (choice B) means showing intelligence or skill, 'Candid' (choice C) means truthful and straightforward, and 'Asinine' (choice D) means extremely foolish or silly. These choices do not accurately reflect the meaning of 'convoluted.'

Correct Answer: C

Rationale: The correct answer is 'Democratic.' A 'Democratic' leadership style involves the leader being open to new ideas and thoughts from the group and encourages group participation in decision-making. This style promotes collaboration, communication, and inclusivity in decision-making processes. 'Laissez-faire' leadership is characterized by a hands-off approach with minimal guidance or direction. 'Autocratic' leadership is where the leader makes decisions without much input from the group. 'Direct' leadership is not a widely recognized leadership style in this context.

Correct Answer: C

Rationale: The correct answer is C. The phrase 'what would she do' is incorrect because in English questions, the word order for modal verbs like 'would' should be 'she would do' instead of 'would she do'. The correct structure should be 'her teacher asked her what she would do after she graduated from nursing school.' Choices A, B, and D are used correctly in the sentence and do not contain any errors.
