October 2010 LSAT Section 5 Question 21
Christopher on June 6, 2018@meisen, this is a weakening question, so we're looking for information that could derail the logic used in the question. The argument is that since the porous outer shell of deep-diving mammals's bones allows those mammals to resurface after a deep dive, any animal that has bones with a porous outer shell must be a deep-diver. Essentially: BPOS ==> DD and contrapositively Not DD ==> Not BPOS.
Margaret on September 4, 2018Well said, thank you very much for explaining!
Stephanie on March 16, 2019why is D incorrect?
Bhavraj on July 3, 2019I can see why C is correct but am having trouble getting rid of D. Can someone explain to me why D does not weaken the argument?
Ravi on July 4, 2019@Margaret, happy Christopher's explanation was helpful!
