Correct Answer: D

Rationale: 'Themselves' is the correct reflexive pronoun to use when referring to 'children' in the plural form. The other options, 'themself,' 'theirself,' and 'theirselves' are not grammatically correct as they do not match the plural subject 'children.'

Correct Answer: A

Rationale: The correct answer is 'Complication.' A complication refers to a secondary issue or difficulty that arises unexpectedly due to another event. It represents an undesired outcome. Choice 'B: Complement' is incorrect as it means something that enhances or completes, not an undesired problem. Choice 'C: Procedures' is incorrect as it refers to methods or steps, not an undesired problem. Choice 'D: Implemented' is incorrect as it means carried out, not an undesired problem.

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: C

Rationale: The correct answer is C, 'pugnacious.' 'Belligerent' means aggressive or combative, which aligns with the definition of 'pugnacious.' Choice A, 'retired,' is incorrect as it does not relate to the aggressive or combative nature of 'belligerent.' Choice B, 'sardonic,' means grimly mocking or cynical, which is not synonymous with 'belligerent.' Choice D, 'acclimated,' means to become accustomed to a new climate or environment, which is unrelated to the meaning of 'belligerent.'

Correct Answer: B

Rationale: The correct answer is 'B: Abrupt.' In this context, 'precipitous' is used to describe a change that occurs suddenly or abruptly. Choice A ('Difficult') is incorrect as it does not capture the sudden nature of the change. Choice C ('Gentle') is incorrect as it conveys the opposite meaning of 'precipitous.' Choice D ('Unanticipated') is incorrect as it focuses on the element of surprise rather than the suddenness of the change.
