June 2010 LSAT Section 5 Question 9
Irina on November 12, 2019@mresende,
Dan on December 1, 2019Can we then say that example 2 IS VALID but NOT SOUND?
Skylar on December 2, 2019@Dan-Engel Yes, that is correct. However, the LSAT is looking for arguments that are both sound and valid, so we care about both. Therefore, a false premise would lead to a flawed argument. Nevertheless, you are unlikely to see this on the LSAT as a false premise is too straightforward for the logic that the exam is looking to test, which is why the video focuses on evaluating if conclusions necessarily follow from the given premises.
