why dose everything eat apples in duolingo !?! is it a sacrid food or something?
It is an easy word to remember and can be eaten. When you learn more vocabulary you will get a more varied diet.
It seems to me that apples grow the world over and would be familiar to everyone. Do they have apples on the six continents? I assume they don't grow in Antarctica. We have orchards in the US and I've seen orchards in France, so that takes care of Europe. Do they grow in Africa and Asia or Oceania and South America? I am assuming that they do.
You will get introduced to new foods later. At least if you get stranded in Paris right now you could survive off of apples for a while.
