A. Pathology
B. Transmission
C. Etiology
D. Mortality rate

Correct answer: C

Rationale: The term 'etiology' refers to the cause or origins of a disease. In this context, the question is asking for the underlying reason or cause of the flu epidemic of 1918. Therefore, the correct answer is C. 'Etiology.' Choice A, 'Pathology,' is incorrect as it refers to the study of diseases rather than the cause itself. Choice B, 'Transmission,' is incorrect as it relates to how a disease spreads rather than its cause.

In a medical context, distention often refers to an abnormal swelling or enlargement of an organ or structure. 'Shrunken' is incorrect as it means reduced in size, 'narrow' is incorrect as it means not wide, and 'flattened' is incorrect as it means pressed or squeezed flat.

Rationale: The correct answer is B: 'To expel feces.' Defecate refers to the act of eliminating solid waste from the body.

B. Autocratic
C. Democratic

Correct answer: C
