The eye drops were intended to _____ the pupils for the eye exam.
- A. dilate
- B. constrict
- C. enlarge

'Constrict' (choice B) means to make smaller, which is the opposite effect needed for an eye exam. 'Enlarge' (choice C) is similar in meaning to dilate but is not the correct term used in this context. 'Decrease' (choice D) means to make less or reduce, which is also the opposite of what is required for an eye exam.

The student observed the tricky procedure with a certain amount of trepidation. What does trepidation mean?
- A. Confidence
- B. Misgivings
- C. Fear
- D. Doubt
Correct Answer: B
Rationale: The correct answer is B: Misgivings. Trepidation means a feeling of fear or apprehension. In this context, the student observed the procedure with a certain amount of trepidation, indicating that they were feeling uneasy or fearful. Choices A, C, and D are incorrect. Confidence (choice A) is the opposite of trepidation, as it denotes a feeling of self-assurance. Fear (choice C) is the closest synonym to trepidation, making it an attractive distractor, but it is not the correct answer. Doubt (choice D) is different from trepidation, as doubt refers to a feeling of uncertainty or lack of conviction, not necessarily fear or apprehension.
What does 'Contract' mean?

- B. To draw together
- C. To elongate

Choices A, C, and D are incorrect because they suggest actions opposite to what contracting means. A: 'To expand,' C: 'To elongate,' and D: 'To dissolve' all indicate actions that involve increasing in size or breaking apart, which are the opposite of what contracting means.
What is the meaning of Diameter?
- A. The width of a structure
- B. The distance across the center of an object
- C. The height of an object
- D. The radius of a circle
Correct Answer: B
Rationale: The correct answer is B. Diameter is defined as the distance across the center of an object, typically a circle. Choice A is incorrect because width refers to the measurement of something from side to side, not necessarily through the center. Choice C is incorrect because height is a measurement from top to bottom, not across the center. Choice D is incorrect because the radius of a circle is the distance from the center to any point on the circle's circumference, not the distance across the center.
