What is the best description for the abbreviation EEG?

Correct Answer: A

Rationale: The correct answer is A: 'A test of brain activity.' EEG stands for Electroencephalogram, a test used to evaluate the electrical activity in the brain. It helps diagnose conditions like epilepsy, seizures, and other brain disorders. Choice B, 'A medical service,' is too broad and does not specifically refer to EEG. Choice C, 'A heartbeat monitor,' is incorrect as EEG does not monitor the heart. Choice D, 'A specialist in dentistry,' is unrelated to the abbreviation EEG.

Correct Answer: C

Rationale: In the context of the sentence, the word 'reflex' indicates a quick, automatic response by the body to a stimulus. The patellar reflex, also known as the knee-jerk reflex, involves the leg extending in response to a tap on the patellar tendon. Therefore, the word 'reaction' aligns closely with the nature of the patellar reflex in terms of a rapid and involuntary response. Choices A, B, and D are incorrect: 'Replication' does not capture the concept of a bodily response, 'convulsion' implies a sudden and uncontrollable movement which is not specific to the nature of the patellar reflex, and 'stretching' does not encompass the automatic and rapid nature of a reflex action.

Correct Answer: D

Rationale: In this sentence, the word 'trepidation' is used to describe the feeling the students had when approaching the cadaver. Trepidation means a feeling of fear or anxiety about something that may happen, so it aligns most closely with the meaning of 'apprehension.' The students were hesitant or worried about facing the cadaver. Choice A ('Wonder') is incorrect as trepidation does not signify a feeling of wonder. Choice B ('Confusion') is incorrect as trepidation is not about being confused. Choice C ('Eagerness') is incorrect as trepidation is the opposite of eagerness; it indicates hesitation or anxiety, not excitement or enthusiasm.

Correct Answer: C

Rationale: The word 'venal' means susceptible to corruption, especially by bribery. It is often used to describe individuals who are willing to do dishonest or immoral acts in exchange for money or favors. Therefore, the most appropriate synonym for 'venal' among the given choices is 'greedy.' 'Vibrant' means full of energy and life, 'savage' refers to fierce or violent behavior, and 'fortunate' means having good luck or being favored by fortune, none of which capture the meaning of 'venal.'
