Which sentence is NOT GRAMMATICALLY CORRECT?

Correct Answer: B

Rationale: Choice B is incorrect due to the use of 'than' instead of 'then.' The correct word in this context is 'then' to indicate the order of actions. Choices A, C, and D are all grammatically correct. In choice A, the sentence structure is correct with a clear cause-effect relationship. Choice C is grammatically sound, describing the dietician's mistake. Choice D is also grammatically correct, showing a cause (the child feeling ill) leading to an effect (the nurse sending him home).

Correct Answer: C

Rationale: The correct answer is 'C: Laid.' 'Laid' is the correct past tense form of 'lay,' which means to put something down. 'Layed' in choice A is incorrect as the past tense of 'lay' is 'laid,' not 'layed.' Choice B, 'Drop,' is incorrect as it does not fit the context of placing something on the table. Choice D, 'Lay,' is the base form of the verb and does not fit the sentence in the past tense.

Correct Answer: A

Rationale: In sentence A, 'fast' is used as an adverb to modify the verb 'moved,' describing how the cars moved quickly. Choices B, C, and D use 'fast' as an adjective, describing the clock, pitch, and cars respectively. Adverbs modify verbs, adjectives, or other adverbs, while adjectives modify nouns or pronouns.

Correct Answer: B

Rationale: The correct answer is "Break." In this context, 'break' is the appropriate word as it means to damage or shatter something. The other choices are incorrect: 'Brak' is a misspelling, 'Brick' is unrelated to the context of the sentence, and 'Brake' refers to a device used to slow down or stop movement, which is not relevant to carrying a bottle to the table.
