IMO CLet's analyze the argument and the provided answer choices to identify which criticism is most applicable.
Argument Breakdown
Premise: When a married couple has frequent emotionally satisfying conversations, they tend in overwhelming percentages to remain married throughout their lives.
Observation: Queen Melinda and Prince Jonathan, Duke of Westphalia, have been married for over sixty years.
Conclusion: Therefore, they must have emotionally satisfying conversations all the time.
Criticism Analysis
(A) It takes a condition to be the effect of something that has happened only after the condition already existed.
This option suggests a temporal confusion where the effect is assumed to have occurred before the cause. However, the argument does not involve such a temporal sequence issue. It is not claiming that the emotionally satisfying conversations happened after the long marriage.
(B) It makes a distinction that presupposes the truth of the conclusions that is to be established.
This option suggests circular reasoning or begging the question, where the conclusion is assumed in the premises. The argument does not explicitly presuppose its conclusion; it infers the conclusion based on the given premise.
(C) It takes one possible cause of a condition to be the actual cause of that condition without considering any other possible causes.
This option is relevant. The argument assumes that the only reason for a long marriage is frequent emotionally satisfying conversations. It does not consider other possible reasons why Queen Melinda and Prince Jonathan might have stayed married for over sixty years, such as social, economic, or personal reasons.
(D) It offers a conclusion that is no more than a paraphrase of one piece of the pieces of information provided in its support.
This option suggests that the conclusion merely restates the premise in different words. However, the conclusion ("they must have emotionally satisfying conversations all the time") is not a paraphrase of the premise; it is an inference drawn from it.
(E) It presents as evidence in support of a claim information that is inconsistent with other evidence presented in support of the same claim.
This option suggests internal inconsistency within the argument. However, the argument does not present conflicting pieces of evidence; it presents a single premise and draws a conclusion from it.
Conclusion
The most appropriate criticism is:
(C) It takes one possible cause of a condition to be the actual cause of that condition without considering any other possible causes.
This criticism is valid because the argument assumes that the long marriage of Queen Melinda and Prince Jonathan is solely due to emotionally satisfying conversations, ignoring other potential factors that could contribute to the longevity of their marriage.
