For the unconscious/intelligence one, I think the correct answer was something like "intelligence does not require consciousness." Does anyone remember that specific choice? If that was really a choice, then that one would have to be correct. If intelligence required consciousness, then by proving animals have intelligence, one would have also proven that animals have consciousness.
Here's a nugget, guys...parallel reasoning, something like #21 in one of the real LR sections:
Mathematics and music educations, music develops math skills, not necessarily because a intellectually nurturing home could be the cause of both. I think the correct answer was the kids with difficulty in class that could have undiagnosed hearing problems. The pattern to replicate was that there could be some third factor that influences both of the identified factors. This was probably the toughest LR question on the test. There were several other answer choices that were really attractive. But I think the kids in class one was the only one that hit on the 3rd factor influencing two previously identified ones.
