Correct Answer: A

Rationale: The abbreviation PDR stands for Physician's Desk Reference, which is a widely used book containing information about prescription drugs, including their uses, side effects, and dosages. Therefore, the abbreviation PDR is associated with drugs. Choices B, C, and D are incorrect because PDR specifically relates to drugs and not procedures, books, or muscle groups.

Correct Answer: A

Rationale: A synthetic drug is one that is artificially created in a laboratory setting rather than occurring naturally. The term 'man-made' accurately describes this process. Choices B, C, and D are incorrect. 'Phony' means fake or fraudulent, not specifically related to synthetic drugs. 'Atypical' means unusual or not typical, which doesn't directly relate to how synthetic drugs are made. 'Futile' means pointless or ineffective, which is not a characteristic of synthetic drugs.

Correct Answer: B

Rationale: The correct answer is B. parietal. The parietal bone is one of the eight bones that form the human skull. It is located near the top of the skull and forms the sides and roof of the cranium. The parietal bones come together at the top of the skull in a structure called the sagittal suture. Choices A, C, and D are incorrect as they do not refer to any cranial bone. 'Partial' means incomplete, 'pariah' refers to an outcast or social reject, and 'parhelion' is a bright spot appearing on either side of the sun.

Correct Answer: B

Rationale: Verified means confirmed or proven to be true. When something is verified, it has been established as factual or accurate through thorough examination or evidence. It is the opposite of belittled, anecdotal, or implicit, as those terms do not convey the sense of confirmation or validation that verified does.

Correct Answer: C

Rationale: The correct answer is C, 'Evisceration.' Evisceration specifically refers to the surgical removal of an organ's contents, for example, the removal of abdominal contents during certain surgical procedures. Vivisection (A) involves performing experiments on live animals, amputation (B) is the removal of a limb, and augmentation (D) is the process of increasing the size, value, or quality of something. Therefore, in the context of surgical procedures, evisceration best fits the description of removing an organ's contents.
