Hey there,
Your question states: Why is little known about the Incas? One thing that I know personally is that they knew how to properly grow things. They were actually the best people who knew how to really grown there crops. But the issue was, there were a very few of these people. There little population just grew smaller and smaller. This would conclude that your correct answer would indicate to be "<span>There were so few of them"
Hope this helps</span>
