Flaw in the Reasoning-#%. The correct answer choice is (A)
In this stimulus, the author presents a very questionable way to determine an average fish weight: anglers got to choose their favorite two fish! They likely have a natural preference for larger fish, so the sample of fish to be weighed is probably going to be heavier than average.
Answer choice (A): This is the correct answer choice; the sample of fish used is likely to be heavier than average, that is, unrepresentative of the general population of fish in the River.
Answer choice (B): The problem is not that the evidence is anecdotal, but that it is not representative of the river's average fish weight.
Answer choice (C): Since the stimulus specifies that the number they seek is the average weight at the beginning of the season, seasonal variation is irrelevant and this answer choice is incorrect.
Answer choice (D): There is no reason to consider figures from past seasons, so this answer choice is incorrect.
Answer choice (E): The author discusses only trout, so it is irrelevant whether or not other types of fish were caught.
