Hi eitijan,
Many of the DS questions that you're going to face on Test Day will test the 'thoroughness' of your thinking. The math itself won't be that difficult, but you'll have to be sure that you're considering more than just the 'obvious' possibilities to get to the correct answer.
We're told that there are MORE than 2 numbers in a list. We're asked if each of the numbers is equal to 0. This is a YES/NO question.
1) The product of any two numbers in the list is equal to 0.
With this Fact, we know that there will be some 0s in this list, but are ALL the numbers going to be 0s?
IF... the list is...
{0, 0, 0} then the answer to the question is YES.
{0, 0, 1} then the answer to the question is NO.
Fact 1 is INSUFFICIENT.
GMAT assassins aren't born, they're made,
