      Hello Mr. Kim, LSAT Dan and the LSATTER Community,

      I’m currently working on the “Extreme Links” Drill on Pg. 460, and one sentence is throwing me off. I’ve checked this website and others and I cannot figure out why the 2nd half of the 3rd sentence of the doll question was diagramed the way it was (per the answers thread).

      Only is tricky for me to diagram in the first place. I usually ask myself “only what?” to identify what only is modifying, making that the necessary condition. However, in this sentence: “…and it can only wear a hat when it wears a purple dress.” we have the words “only” and “when.” The “when” in this sentence seems like an if / sufficiency indicator. I originally diagrammed it like this:

      PD > H

      The correct way is: H > PD

      Where am I going wrong, and what would be a good strategy to attacking questions like this? Thank you for any help!

      I think I may have figured it out. Does “when” in this case actually act as “if?” So effectively, is this saying “only if?”

      Yes…it’s equivalent to “only if.”
