Correct Answer: C

Rationale: In this context, the word 'quandary' refers to a state of uncertainty or confusion caused by being faced with a difficult decision or choice. This matches the meaning of option C. Choices A, B, and D are incorrect because 'quandary' does not relate to a place where rocks are mined (A), a journey of discovery (B), or a major attempt or trial (D), but rather to a state of uncertainty or confusion.

Correct Answer: C

Rationale: In this sentence, the word 'exposure' is used to refer to coming in contact with the flu virus. Therefore, in this context, the meaning of 'exposure' is related to 'contact.' Choices A, B, and D are incorrect. 'Disclosure' means revealing information, 'pretense' means pretending, and 'display' means to show or exhibit, none of which captures the intended meaning of 'exposure' in the sentence provided.

Correct Answer: D

Rationale: A UTI (Urinary Tract Infection) is likely to involve the bladder. A urinary tract infection is an infection in any part of the urinary system, which includes the kidneys, ureters, bladder, and urethra. The most common type of UTI is a bladder infection where bacteria enter the bladder and cause inflammation and infection. Choices A, B, and C are incorrect because a UTI specifically affects the urinary tract system and not the bones, throat, or stomach.

Correct Answer: B

Rationale: The word 'mercurial' in this sentence means unpredictable or prone to sudden changes in mood or behavior. Justin's temperament can be characterized as unpredictable, which is causing him to not work well with others. Choice A, 'Continuous,' does not align with the meaning of 'mercurial' as it implies a steady, uninterrupted flow. Choice C, 'Mercenary,' refers to being primarily motivated by money or reward, which is not the context here. Choice D, 'Miraculous,' means extraordinary or remarkable, which is not the intended meaning in this sentence.

Correct Answer: B

Rationale: In the context of the sentence, the word 'supplement' is used to mean adding something extra to enhance or complete the diet. Therefore, the meaning of the word is 'add to.' Choice A ('Replace') is incorrect because 'supplement' does not mean to substitute or exchange. Choice C ('Reflect') is incorrect because 'supplement' does not mean to mirror or show. Choice D ('Parallel') is incorrect because 'supplement' does not mean to correspond or be similar in a particular way.
