#19 - Concept Reference, Must Be True

[James Finch]

Hi Christian,

Yes, this is a question that requires a very close reading of the scope of the claim made in the passage. The claim about exceptional memory is only applicable to chess pieces, and then only if they are in a typical configuration. We know nothing about the memory of chess prodigies outside of these two potential situations of chess pieces: either in a typical configuration or an atypical one. So the only inference that can be made based on this claim is about chess prodigies' memory regarding chess pieces. Only (D) gives us that proper scope, with all the other answer choices being far too broad.

Good job identifying the issue!

I have a question regarding answer choice A. When the answer choice says "typical of games other than chess" that means it is typical of games other than chess, but it (could be true?) that those sequences of moves are also typical of chess games?

Hi Musa,

We don't need to consider whether it's typical of games other than chess or if it's typical of chess because ultimately, sequences of moves are outside the scope and never discussed in the passage.

Best,
