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: The correct answer is A: 'Measures contributing to cleanliness.' In the given sentence, 'hygiene' refers to practices that promote cleanliness and health, such as washing hands, taking showers, and maintaining a clean environment. Choice B, 'Financial resources,' is incorrect as hygiene does not pertain to money matters. Choice C, 'Insurance,' is unrelated to the concept of hygiene. Choice D, 'Friendliness,' is also incorrect as it does not align with the context of personal cleanliness and health.

Correct Answer: B

Rationale: The word 'that' is the correct relative pronoun to use in this context to refer to the people who were present that night. 'Whom' is used for objects of a verb or preposition, 'which' is used for things, and 'whose' is a possessive pronoun.

Correct Answer: A

Rationale: The correct answer is 'bilateral.' 'Bilateral' means having two sides or affecting both sides. 'Insufficient' means not enough or inadequate, 'bicuspid' refers to a two-pointed tooth, and 'congruent' means in agreement or harmony. Therefore, 'bilateral' is the only word among the choices that specifically relates to being on both sides.

Correct Answer: A

Rationale: The correct contraction for 'will not' is 'won't'. 'Willn't' (Choice B) is not a standard contraction in English. 'Wouldn't' (Choice C) is the contraction for 'would not,' not 'will not.' 'Will'nt' (Choice D) is not a recognized contraction in English. Therefore, 'won't' is the correct choice as the contraction for 'will not.'
