<p>Sorry for number 1, now that I read it again, I think the answer should be grassland because its land is fertile. It says “supply”, not a great source of food. We are not allowed to capture wild animals for food anyway, so E shouldn’t be right.</p>

<p>What is the answer to question 83? There is no evidence for gravity, although initially I thought the arrow was provided. Is the experiment only “leaving the seed in the dark on a moist paper”? It’s kinda vague but is the answer A? I don’t think there’s evidence for B C D E…</p>
