What is tepid bathwater?

Correct Answer: B

Rationale: Tepid bathwater refers to water that is neither too hot nor too cold, but rather lukewarm in temperature. It is a comfortable and soothing temperature for bathing or soaking. Choice A is incorrect because tepid water is not salty. Choice C is incorrect because icy water is cold, not tepid. Choice D is incorrect as half-full refers to the quantity of water, not its temperature.

Correct Answer: A

Rationale: A stye is an infection that occurs at the base of an eyelash or on the eyelid. It is typically caused by a bacterial infection, leading to redness, swelling, and sometimes discomfort in the affected area. Choices B, C, and D are incorrect because a stye specifically refers to an infection of the eyelid area, not the eardrum, nostril, or scalp.

Correct Answer: D

Rationale: The abbreviation LBW stands for 'Low Birth Weight,' which specifically refers to the weight of the infant at birth. It is an important indicator of the baby's health and development, with low birth weight infants often requiring special medical attention and care. Choices A, B, and C are incorrect because LBW does not relate to genetic makeup, feeding schedule, or Babinski response; rather, it is a term used to describe infants who are born weighing less than normal, which can have implications for their health and require additional monitoring and support.

Correct Answer: D

Rationale: In this context, the word 'sanctioned' means to authorize or approve. The sentence indicates that the professor gave permission for the field trip to the chemistry lab, which aligns with the meaning of 'authorized.' Choices A, B, and C are incorrect. 'Organized' does not fit the context as the sentence is about granting approval, not arranging. 'Deterred' means to discourage, which is the opposite of what the professor did. 'Neglected' means failed to care for or pay attention to, which is unrelated to the professor approving the field trip.

Correct Answer: B

Rationale: When tubes distend, they expand or become enlarged, which typically results in stretching rather than flexing, solidifying, or collapsing. Distending tubes imply an increase in size or volume, indicating a stretching or expansion effect. Therefore, the correct answer is 'stretch.' Choice A, 'flex,' is incorrect as flexing refers to bending or curling, not expanding. Choice C, 'solidify,' is incorrect as solidifying refers to becoming solid, which is not related to the expansion of tubes. Choice D, 'collapse,' is incorrect as collapsing refers to falling in or giving way, which is the opposite effect of distending.
