December 2004 LSAT Section 2 Question 2
Melody on December 16, 2013This argument does not contain sufficient and necessary sentences, so we cannot diagram it. You are correct to identify this as a cause and effect weaken argument. The commentator is trying to weaken the claim that "the release of chlorofluorocarbons into the atmosphere is harming humans by damaging the ozone layer, thus allowing increased amount of ultraviolet radiation to reach Earth." The claim states: damage to the ozone layer causes harm to humans. You are correct to point out that the commentator, in an attempt to weaken this cause and effect argument, is trying to show cause without effect, i.e. "300,000 years ago a supernova greatly damaged the ozone layer, with no significant effect on our earliest ancestors." Great work!
