Rationale: The term 'flaccid' is commonly used to describe something that is limp, soft, or lacking firmness. It suggests a lack of stiffness or rigidity, often used to describe plants, muscles, or other objects that are in a drooping or loose state.
Choice A 'Light-colored' is incorrect as it does not convey the meaning of flaccid.
Choice C 'Uncontaminated' and
Choice D 'Unusually aggressive' are also incorrect as they do not relate to the definition of flaccid.

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.

Choice

Rationale: In this sentence, the term 'yaw' refers to a movement where the robotic arm moves side to side. The context suggests that the arm is exhibiting too much of this side-to-side movement and requires adjustment to rectify the issue.
Choice A, 'to gape open,' is incorrect as 'yaw' does not imply opening.
Choice B, 'to move up and down,' is incorrect as 'yaw' specifically refers to side-to-side movement.
Choice C, 'to close tightly,' is incorrect as it does not relate to the movement described in the sentence.

Correct Answer: D

A), 'steres' (choice
B), and 'sterol' (choice
C) are not correct terminologies for the breastbone.
