I find that the support for AC A is in the first few sentences of Passage B. Passage B says, "I am always astonished at how falsely I remember things, astonished at how unreliable memory is. AND EVEN WHEN I KNOW A MEMORY IS INCORRECT ... " This suggests that Passage B is only dealing with those instances when the author clearly identifies that a memory is false, which means that there are instances in which mistakes of the unintentional variety occur. The author's characterization of such cases is attributed to the falsity of memory, which the author characterizes as an inevitability rather than something "unforgivable."

These answers, specifically in the stimulus and for answer choice A, should be edited. The author does not rely on the truth of a claim by a biased source. The author does not touch the truthfulness of the chocolate claim or the oily food claim. It treats these reports as events when it concludes, "almost any food will be reported to be healthful." Reported makes no comment on the truthfulness of the claim. So the biased source error does not occur.
