Choose the meaning of the word 'riddled' in the following sentence: 'The cavity, once opened, proved to be riddled with infection.'

Correct Answer: B

Rationale: The word 'riddled' in this context means filled with or affected by (something undesirable) to a great degree, which aligns with the definition of 'overrun.' In this sentence, the cavity is described as being full of infection, indicating that the infection has spread extensively throughout. 'Challenged' (choice A) implies being tested or provoked, which is not the meaning conveyed by 'riddled.' 'Separated' (choice C) means divided or isolated, which does not fit the context of the sentence. 'Complete' (choice D) means finished or whole, which is the opposite of what is described in the sentence where the cavity is full of infection.

Correct Answer: A

Rationale: In the sentence, the word 'suppress' is synonymous with the word 'subdue.' To suppress a cough means to reduce or restrain it, which aligns with the meaning of subdue. The other options are incorrect: 'Cure' implies completely eliminating the cough, 'Restore' means to bring back to a former condition, and 'Affect' is too general and does not capture the specific meaning of 'suppress' in this context.

Correct Answer: A

Rationale: The term septic typically refers to something that is infected or contaminated with harmful bacteria or toxins, often used in the context of septic tanks or infections. Therefore, the correct answer is 'Infected.' Choices B, C, and D are incorrect. Odorous means having a smell, terminal means leading to death or the end of something, and vigorous means strong or energetic. These terms do not capture the essence of septic as being infected.

Correct Answer: B

Rationale: The correct term for the kneecap is patella. It is a small, flat bone that sits at the front of the knee joint and helps in the transmission of force between the thigh and lower leg while providing protection to the knee joint. 'Patina' refers to a green or brown film on the surface of bronze or similar metals, 'pastel' is a pale, soft shade or color, and 'pathogen' is a bacterium, virus, or other microorganism that can cause disease.

Correct Answer: A

Rationale: The correct answer is A, 'Insignificant.' Paltry and insignificant are synonymous terms that denote something as unimportant, trivial, or of little value. Choice B, 'Punitive,' means inflicting or intended as punishment, which is unrelated to the meaning of paltry. Choice C, 'Prolonged,' means continuing for a long time, which is not a synonym for paltry. Choice D, 'Economical,' means giving good value or service in relation to the amount of money, which is not synonymous with paltry.
