Correct Answer: D

Rationale: The term 'doleful' is best described as feeling or expressing sorrow or sadness. 'Downcast' aligns with this meaning as it refers to having a dejected or low spirit, which matches the nature of doleful. Options A, B, and C do not directly relate to the sense of sadness or sorrow that doleful conveys. 'Unwell' means in poor health, 'deprived' means lacking something essential, and 'conceited' means having an excessively favorable opinion of oneself, none of which capture the essence of doleful.

Correct Answer: B

Rationale: A mass of tissue formed in the ovary is known as the corpus luteum. The corpus luteum is a temporary endocrine structure involved in the production of progesterone, which is essential for preparing and maintaining the uterus for pregnancy. Choices A, C, and D are incorrect. Corpus delicti refers to the body of a crime, corpus striatum is a part of the brain, and corpus callosum is a structure that connects the two hemispheres of the brain.

Correct Answer: C

Rationale: The word 'inquest' typically refers to a legal investigation or inquiry, especially into the cause of someone's death. In this context, an 'inquest' is associated with conducting an autopsy to determine the cause of death. Choices A, B, and D are incorrect. A 'tryout' refers to a test or trial, 'intake' relates to the process of taking something in, such as food or air, and a 'checkup' is a general medical examination.

Correct Answer: C

Rationale: Hypothetical is best defined as being assumed because it describes something that is based on a theory or assumption rather than solid proof or certainty. Hypothetical situations are used to explore different possibilities or outcomes without being confirmed as true or existing. Choice A, 'rigorous,' does not accurately define hypothetical, as it refers to something that is extremely thorough, accurate, or carefully done. Choice B, 'short-term,' is unrelated to the definition of hypothetical. Choice D, 'convinced,' does not capture the essence of hypothetical, which is more about assumptions and possibilities rather than being convinced of something.
