Choose the meaning of the word quandary in the following sentence: 'Too many potential job choices put Martin in a quandary.'

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: D

Rationale: In the given sentence, the word 'establish' is used in the context of identifying or finding out the specific causes of contact dermatitis through patch tests. The most fitting description for 'establish' in this context is 'Determine,' as it signifies the action of figuring out or ascertaining the specific causes. 'Launch,' 'introduce,' and 'endorse' do not capture the essence of what the physicians are doing in this scenario. They are not launching, introducing, or endorsing the causes; instead, they are trying to determine them through the patch tests.

Correct Answer: C

Rationale: Contact dermatitis occurs through the sense of touch when the skin comes into direct contact with irritants or allergens, leading to an inflammatory reaction. This condition is commonly caused by the skin being in contact with items like certain chemicals, fabrics, plants, or metals, resulting in redness, itching, and sometimes blisters. The other choices (smell, taste, sight) do not relate to the cause of contact dermatitis, which specifically involves the skin's direct contact with irritants or allergens.

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: C

Rationale: In this context, 'projected' is used to indicate an estimation or prediction of the duration of the treatment. Therefore, it aligns closest in meaning to 'estimated.' Choice A, 'Protruded,' means to extend beyond or above a surface, which does not fit the context of the sentence. Choice B, 'Guaranteed,' means to provide assurance, which is not the intended meaning in the sentence. Choice D, 'Alleged,' means to claim without proof, which is not the correct interpretation in this context.
