Correct Answer: B

Rationale: The correct answer is B: 'Regretful.' Contrite means feeling regret or remorse. 'Guilty' (A) refers to being responsible for a wrongdoing, not necessarily feeling remorseful. 'Shameful' (C) means feeling ashamed, which is related but not the same as feeling regret. 'Pleased' (D) means feeling satisfied or happy, which is the opposite of contrite.

Correct Answer: A

Rationale: Concave means rounded inward. When something is concave, it curves inwards like the interior of a bowl. Choice B, 'Rounded outward,' is incorrect as this describes a convex shape, not concave. Choice C, 'Straight,' is incorrect as concave refers to a curved shape, not a straight one. Choice D, 'Flat,' is also incorrect as it does not describe the inward curve characteristic of concave shapes.

Correct Answer: B

Rationale: The correct answer is B. Distal means further away from the point of attachment. This term is commonly used in anatomy to describe the location of a body part relative to the point of attachment or the trunk. Choice A is incorrect because it describes the term Proximal, which means closer to the point of attachment. Choice C is incorrect as it describes the term Medial, which means toward the middle of the body. Choice D is incorrect as it describes the term Superficial, which means on or near the surface.

Correct Answer: B

Rationale: The term 'Gravid' means being pregnant or expecting a child. Therefore, the correct answer is B. Choice A, 'Thin,' is incorrect as it does not relate to the term Gravid. Choice C, 'Infected,' is also incorrect as it is not a relevant description of the term. Choice D, 'Healing,' is unrelated to the term Gravid and is therefore incorrect.

Correct Answer: A

Rationale: The correct answer is 'A: his injury.' In the context of completing a race, an injury would be a significant obstacle to overcome. While choices B, C, and D could also pose challenges, an injury is the most severe hindrance that would make completing a race particularly difficult. His condition, pain, or fatigue may affect performance, but they are not as directly impactful as an injury in this scenario.
