Select the meaning of the word 'overt' in the sentence: 'Despite the absence of overt signs, Dr. Harris suspected Alicia might be suffering from the flu.'

Correct Answer: B

Rationale: The correct answer is B: 'apparent.' In the given sentence, 'overt' is used to describe signs that are evident or obvious. It indicates that Dr. Harris suspected Alicia might have the flu even though there were no clear or overt signs present. Choice A, 'concealed,' is incorrect as it means hidden or not easily visible, which is the opposite of 'overt.' Choices C and D, 'expert' and 'delectable,' are unrelated to the meaning of 'overt' in this context.

Correct Answer: D

Rationale: 'Paroxysm' is the correct answer as it refers to a sudden, violent seizure or outburst. The other choices are incorrect because 'revelation' means a surprising and previously unknown fact, 'nutrient' refers to a substance that provides nourishment, and 'contraption' means a machine or device that is strange or unnecessarily complicated.

Correct Answer: B

Rationale: The correct answer is B: 'meat-eating.' The term 'carnivore' specifically refers to an animal that primarily consumes meat. Choices A, C, and D are incorrect because 'hungry' means feeling the need to eat, 'infected' refers to being affected by a disease or pathogen, and 'demented' means to be mentally disturbed.

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: 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.
