Help with economics paper!!?

I think the question being posed to you is: if China is buying up a large majority of the soybean crop, how does that affect the market? Does it cause competition for whatever is left among the remainder of buyers? Does it drive up prices? Does it lower them? How does this affect the market, and competition for resources? I hope this helps! Use the proper terms in your text to back your explainations and assertions! :)
