Correct Answer: A

Rationale: The word "ubiquitous" means present, appearing, or found everywhere. Another word that closely relates to this meaning is "widespread," which also refers to something that is prevalent or found in many places. The other choices, such as "last demand," "uncertainty," and "finally reckoned," do not accurately represent the synonym for "ubiquitous."

Correct Answer: B

Rationale: The correct answer is B: 'Limp or lacking tone.' Flaccid refers to something that is lacking firmness or muscle tone. Choice A, 'Rigid,' is incorrect as it is the opposite of flaccid. Choice C, 'Tense,' is also incorrect as it implies stiffness or tightness, which is different from being flaccid. Choice D, 'Swollen,' is unrelated to the meaning of flaccid.

Correct Answer: B

Rationale: The correct answer is B, 'Worsening.' Deteriorating refers to something getting worse over time, not improving (choice A), staying the same (choice C), or fluctuating (choice D).

Correct Answer: A

Rationale: The correct answer is A: 'Occurrence.' Incidence refers to the frequency or occurrence of something happening. Choice B, 'Disappearance,' is incorrect as it means vanishing or ceasing to exist. Choice C, 'Growth,' is incorrect as it refers to an increase in size, number, or development. Choice D, 'Repetition,' is incorrect as it means the action of repeating something that has already been said or written.

Correct Answer: A

Rationale: The word 'assured' means to have made certain or confident of something. 'Confirmed' is a synonym that aligns with this meaning. Therefore, the correct answer is A, 'Confirmed the truth of.' Choice B, 'Sympathized with,' does not have a similar meaning to 'assured.' Choice C, 'Denied the truth of,' is the opposite in meaning to 'assured.' Choice D, 'Made known to,' does not convey the same sense of certainty as 'assured.'
