Correct Answer: D

Rationale: The word "acute" in this sentence means intense. Acute pain is sharp or severe, which accurately describes the level of pain experienced during childbirth. Choice A, "Escalating," suggests increasing pain over time, which is not necessarily implied by the word "acute." Choice B, "Emergent," means arising or coming into view, which does not capture the intensity of the pain. Choice C, "Eased," means to make less severe, which is the opposite of what is described in the sentence.

Correct Answer: B

Rationale: Concise is best defined as being brief or to the point, expressing much in few words. While accuracy and exactness are important qualities, concise specifically refers to being brief or succinct in communication. Choice A ('exact') is not the best definition, as being precise in language does not necessarily mean being concise. Choice C ('accurate') is also not the best definition, as accuracy relates more to correctness than brevity. Choice D ('assembled') is unrelated to the definition of concise.

Correct Answer: C

Rationale: The phrase 'monitor progress' in this context means to observe or keep track of how the pilot program is developing or improving. It involves regularly reviewing reports and conducting inspections to ensure that things are progressing as expected. 'Keep an eye on improvement' accurately describes the action of monitoring progress in this scenario, making it the correct choice. Choices A, B, and D are incorrect as they do not capture the essence of overseeing development and ensuring improvement.

Correct Answer: B

Rationale: The word 'deferentially' means showing respect or submission to someone. Therefore, the closest synonym for 'deferentially' is 'respectfully' as it reflects the attitude and behavior of showing respect towards others. The other choices are incorrect: 'Imperfectly' means with flaws or errors, 'Competently' means having the necessary ability or skills, and 'Energetically' means with energy or enthusiasm, none of which capture the respectful connotation of 'deferentially.'

Correct Answer: A

Rationale: In the context of the sentence, 'volatile' means likely to change rapidly and unpredictably or evaporate quickly. When referring to liquids, volatile typically implies that the liquids are unstable and can easily change from liquid to gas. Therefore, the most appropriate meaning of 'volatile' in this sentence is 'unstable.' Choices B, C, and D are incorrect because 'abnormal' and 'lethal' do not capture the essence of rapid change or evaporation associated with volatile liquids, while 'blended' is unrelated to the characteristics of volatile liquids described in the sentence.
