Correct Answer: B

Rationale: In this context, 'who' is the correct relative pronoun to refer to people. 'That' is used for things, 'which' is used for animals or things, and 'whom' is an object pronoun, not needed in this sentence. Therefore, 'who' is the most appropriate choice.

Correct Answer: B

Rationale: The correct answer is B. If someone is described as assiduous, it means they are diligent, hardworking, and persistent in their efforts. This aligns with the trait of being 'Industrious.' Choices A, C, and D are incorrect because being lazy, inconsistent, or procrastinating are the opposite characteristics of someone who is assiduous.

Correct Answer: B

Rationale: The correct answer is B: 'Withered.' When a body part atrophies, it shrinks or wastes away. This term is associated with a decrease in muscle mass or tissue due to various reasons like lack of use or injury. Choices A, C, and D are incorrect because atrophy does not refer to enlargement, swelling, or damage, but rather to wasting away or shrinking.

Correct Answer: D

Rationale: The term 'discrete' means individually separate and distinct. Therefore, the most appropriate choice to describe the symptoms that are distinct and separate from each other is 'separate' (option D). Choices A, B, and C are incorrect because they do not convey the specific meaning of the term 'discrete' as separate and distinct.

Correct Answer: B

Rationale: The correct answer is 'never shone' as the sentence is discussing a past event (Saturday). 'Never shone' is the correct past tense form to describe the sun not shining on a specific day in the past. Choices A, C, and D are incorrect because they do not provide the appropriate past tense form needed in this context. 'Never shines' is present tense, 'rarely shines' implies occasional shining, and 'sometimes shines' suggests occasional shining as well, none of which accurately convey the past event of the sun not shining on Saturday.
