LR Question 23 Explanation

QUESTION TEXT: An advertisement states: Like Danaxil, all headache pills…

QUESTION TYPE: Must be True

ANALYSIS: This question demands a careful reading. It did not say that Danaxil cures headaches faster than all other pills. It said “no headache pill stops pain more quickly.”

That means that no pill is faster. But another pill could be just as fast as Danaxil. It’s even possible that every pill acts with exactly the same speed.

___________

  1. The ad says that all headache pills can stop your headache.
  2. The ad only says that no other pill is faster. It didn’t claim that another pill couldn’t be equally fast.
  3. CORRECT. This has to be true, since no pill is faster than Danaxil.
  4. We have no evidence for this. Danaxil might well be faster.
  5. The stimulus says Jane takes a competing pill, not Danaxil. It also doesn’t tell us why she takes it.

Recap: The question begins with “An advertisement states: Like Danaxil, all headache pills”. It is a Must be True question. Learn how to master LSAT MBT questions on the LSAT Logical Reasoning question types page.
