QUESTION TYPE: Paradox
PARADOX: Cold weather usually weakens muscles in cold-blooded animals. But, the veiled chameleon can extend its tongue almost as fast when temperatures are lower. The veiled chameleon is cold-blooded.
ANALYSIS: We only know cold affects muscles. So, the obvious solution is that the chameleon’s tongue extension is not muscle powered.
The information given about tongue retraction actually isn’t necessary. It just illustrates what we already know: cold weather slows down muscles. So presumably, tongue retraction is muscle powered.
- This statement makes sense, but we’re not just looking for an answer that’s true. We have to resolve the paradox.
- This doesn’t tell us why cold weather doesn’t slow down those tongues.
- This doesn’t say anything about tongues! All it tells us is that veiled chameleons can survive in a variety of environments. But they will still slow down if it’s cooler.
- CORRECT. This shows that tongue extension isn’t muscular, and therefore isn’t affected by the cold the way muscles are.
- So? Stronger muscles will still be slower when it is cold. The stimulus said things are slower, which is a relative term. Strong is an absolute term.
Also, this is talking about the retraction muscles, when the question is about the extension mechanism.
