Question

Which sentence shows a flaw or mistake in logic?

Answer 1

Sentence 2. Just because digital music players are being sold doesn't mean that crime rises. (if it does, it would be merely coincidental)

Answer 2

The answer would be B, "Violent crime in the U.S. fell every year until 2004, when digital music players became widespread, leading to a rise in crime" because the logic states that digital music players are the cause of the rise of violent crime.
