LG Game 4 Question 20 Explanation, by LSATHacks

W doesn’t have to perform any traditional pieces. A is CORRECT.

You can prove this by making a diagram that doesn’t have W performing any traditional pieces.

It’s best to start at the low end, anyway. There’s no obvious reason why W has to perform traditional pieces, so you might as well see if you can hit zero.

This diagram obeys all the rules. I used the second scenario, because the first scenario has W performing a traditional piece.
