问题 The passage suggests that a lack of modern sanitation would make which of the following most likely to occur?
Which of the following best describes the organization of the passage?
选项 A、A paradox is stated, discussed and left unresolved.
B、Two opposing explanations are presented, argued, and reconciled.
C、A theory is proposed and is then followed by descriptions of three experiments that support the theory.
D、A generalization is stated and is then followed by three instances that support the generalization.
E、An argument is described and is then followed by three counterexamples that refute the argument.
答案D
解析 The best answer choice is D. The passage begins with a general statement that epidemics can occur without genetic changes in the bacteria and viruses that cause them, and then presents three instances of epidemics that did not have their origins in genetic changes. Choices C and E are incorrect because the passage does not describe experiments or provide counterexamples to refute an argument. Choices A and B do not accurately describe the organization of the passage.
