1. What does the word BILATERAL mean?

A. 2-sided
B. Straight
C. Symmetrical

Correct answer: A

Rationale: The word 'bilateral' means having or relating to two sides. It is often used to describe something that occurs on both sides, such as bilateral symmetry in which an object is symmetrical on two sides. Choice B, 'Straight,' does not capture the meaning of bilateral. Choice C, 'Symmetrical,' while related, does not specifically convey the idea of something pertaining to two sides. Choice D, 'On one side,' is the opposite of what bilateral means.

Choice B, 'Clearly,' is incorrect as it does not reflect the primary meaning of the word. Choice C, 'In our opinion,' is incorrect as it does not capture the essence of 'principally.'

A. Careless
B. Skillful
C. Inexperienced
D. Lazy

Correct answer: B

Rationale: The word 'adroit' means skillful or proficient. A surgeon who is adroit would be highly skilled and proficient in their work.

5. Which sentence uses the correct form of the verb?

A. She has completed the project
B. She has completed the project
C. She has been completed the project
D. She has completed the project

Correct answer: B

Rationale: The correct answer is 'She has completed the project.' The sentence uses the present perfect tense with 'has completed,' which is the correct form of the verb. Choice A is incorrect due to the subject-verb agreement error ('She' requires 'has' instead of 'have'). Choice C is incorrect as it changes the meaning by using the passive voice 'has been completed' instead of the active voice. Choice D is incorrect as 'complete' should be 'completed' to match the present perfect tense.
