The issue I'm having with C is the wording in the stimulus. The stimulus states that "the reasoning power and spatial intuition exercised in chess-playing also contributed to achievement,..." The conclusion did not explicitly highlight the chess program, but rather chess-playing as a whole. Since students who are joining an after school chess team are still (presumedly) engaging in chess-playing, wouldn't C actually strengthen the argument (or at the very least, not undermine it)? I feel like in order for C to be correct, the stimulus would have had to state the reasoning power and spatial intuition exercised in the program also contributed to achievement."

Could someone explain this in more detail?

I was trying to find an answer that said the Walnut Lane location was part of the Main Street location, and then it hit me that Pat just isn't a FVC member

Can someone explain why B is not the right answer choice. I was translating B into a logical diagram based on the "unless equation." The condition that follows unless ("resources managers regualrly intervene in most of the world's remaining forests) becomes the required condition. Then, we negate the second part (many of the world's most endangered species will not survive) and make it the sufficient condition. Accordingly, this would be F --> RI, which matches what is listed. However, this is not the correct answer. Would appreciate a better explanation as to why A is a better choice than B
