From Power score:
While peppers were common to each meal, note that Monroe is someone with a generally poor appetite and here he is eating sizable portions in each case. Could that perhaps be the cause? Yes, definitely, and this problem focuses on that oversight.
The interesting thing in this question stem is that we are told that "both Monroe's conclusion and the evidence on which he bases it are correct," which means that we now have to accept that Monroe was right about the hot peppers being the sole cause of him becoming ill after the three meals in question. The idea discussed in #20, namely that it was the large quantities of food that caused the issue in the three meals, now has to be set aside (and that is hard to do!).
So, with the above in mind, let's look at some of your answer comments again:
Answer choice (A): Yes, this is far too broad, and it also looks into possible future meals, which haven't been addressed. We don't know anything about the daily specials, and it is possible that some other element—one that Monroe has yet to encounter—might make him sick, or that at future meals different factors might be in play.
Answer choice (B): This is the correct answer choice. "I eliminated B because it didn't account for the size of the food that Monroe was eating." — as you've probably figured out now, the fact that this didn't address the amount of food eaten isn't a problem (since we are ignoring that element per the question stem). Instead, because this answer specifies that Monroe would've eaten hot peppers with this meal (which was a substitute for one of the three meals we already know about, where the hot peppers were indeed what was making him sick), we can ascertain that he would have for sure become sick after this meal. Thus, this answer choice is strongly supported by the information in the stimulus, and is correct.
Answer choice (C): This answer choice has some similarities to (A). First, this is a forward-looking answer that talks about the next time, and at that point things could be entirely different. What we know about is what happened at the three meals discussed in the stimulus, and what happens thereafter is not bound by the same rules or conclusions. By comparison, look at answer choice (B), which quite specifically substitutes the food used in one of the three named meals in the stimulus.
So, while we know that when Monroe ate hot peppers at those meals and that caused him to become sick, for a future meal we can't guarantee what will happen, or that some other factor won't cause him to be sick.
Answer choice (D): We simply do not know what occurred prior to the three meals Monroe describes. The time in the stimulus where he describes eating friend shrimp could have been the very first time Monroe ever ate fried shrimp.
Answer choice (E): Again, we have no way of knowing this to be true. It is possible, but it does not have to be the case, and is thus an incorrect answer. Monroe may have eaten hot peppers before ever going to Tip-Top, and he may or may not have gotten sick afterwards. We just don't know enough about Monroe to conclude this; all we know is that the three times Monroe has eaten at Tip-Top, the hot peppers made him ill.
