Check the original text. Isn't it "Shor'a'i donaruka, naniga okoruka nado yosoku surukoto"? (Not "Shoroi" but "Shorai", right?) shorai=(in) the future donaruka=what will become of naniga okoruka=what will happen nado=and so on. etc. yosoku surukoto= to foresee. to predict. "To predict what things will be or what will happen in the future." (The line is not a perfect sentence. It's more like a noun clause. It lacks in the main verb, at least.)
