I was able to narrow this question down to C and E, then incorrectly chose E. I now see that the question stem takes out any uncertainty for the validity of the answer choices. This is helpful. I chose E because I thought C was going too far indicating that most people will decide they have to have the game after playing it during the playable period. But since the question stem requires us to consider this option as if it were true, this clearly makes sense.
Still, could someone please help to explain why E is wrong? Is it considered out of scope, since it doesn't actually provide a method of increased sales?
Thanks!
