A) the CISG did not cover the contract because metals are not covered by it,which includes powered metals,so Austrian law (where the contract was signed) would govern
B) the CISG did not cover the contract because metals are not covered by it,which includes powered metals;the UCC would govern the contract because it was signed in the U.S.and most transactions took place there
C) the CISG governed and the courts would look to the past dealings of the parties since the written contract was not clear on the issue at hand;Treibacher prevailed
D) the CISG governed and the courts would look to the past dealings of the parties since the written contract was not clear on the issue at hand;Allegheny prevailed
