Additional Premise and Counter-Premise Recognition Mini-Drill #3

[oscarchi]

Hi,

The answer to argument #3 on page-21 of THE POWERSCORE LSAT LOGICAL REASONING BIBLE, doesn't mentioon if the additional premise, After all, nothing in those documents was as valuable as the money in the safe, in this argument is central or non-essential, as what the Anser Key does to argument #2.

Could you help me find the answer, as well as some discussion and explanation for it?


Thanks a lot.

Hi Oscar,

Thanks for the question. On a certain level, every premise and additional premise is important. But to specifically answer your question, in Question #3, as in Question #2, the additional premise is central to the conclusion. This occurs because in determining that the robbery was unsuccessful, the author admits that documents were stolen. On its face, that sounds like a success, so the author needs a comparison--which is provided in the additional premise--to show that the most valuable thing there wasn't stolen.

Please let me know if that makes sense. Thanks!
