My mother and _____ went shopping for clothes yesterday.
- A. me

If someone is disseminating information, what are they doing?
- A. Hiding it
- B. Broadcasting it
- C. Destroying it
- D. Withholding it
Correct Answer: B
Rationale: The correct answer is B: 'Broadcasting it.' Disseminating information means spreading or sharing it widely to reach a broader audience. Choice A, 'Hiding it,' is incorrect as disseminating involves making information known, not concealing it. Choice C, 'Destroying it,' is incorrect as disseminating means to distribute, not to eliminate. Choice D, 'Withholding it,' is incorrect because withholding information means keeping it back rather than sharing it openly.
What do contours refer to?
- A. Color
- B. Shape
- C. Size
- D. Texture
Correct Answer: B
Rationale: Contours refer to the shape or outline of something. They represent the boundaries or curves that define the outer edges of an object or form. Colors, sizes, and textures do not encompass the concept of contours, making them incorrect choices in this context.
If they _____ that the weather was going to be so bad, they wouldn't have gone to the beach.
- A. knew
- B. had known
- C. knew
- D. could have known
Correct Answer: B
Rationale: The correct answer is 'B: had known.' In this conditional sentence, the past perfect tense is required to indicate that knowing about the weather should have happened before going to the beach. 'Knew' (choice A and C) is in the simple past tense, which doesn't convey the sequence of events accurately. 'Could have known' (choice D) is incorrect as it implies a possibility of knowing in the past, but it doesn't fit the context of the sentence where the emphasis is on prior knowledge before going to the beach.
