推导题。文章第二段最后两句提到Southwick’s on the reduction of space or the withholding of food failed to produce more than temporary, increases, in intragroup aggression. Indeed, food deprivation not only failed to increase aggression but in some cases actually resulted in decreased frequencies of aggression，即食物的减少会产生“more than temporary, increases, in hatragroup aggression”，但在某些情况下“resulted in decreased frequencies of aggression”，D项temporarily与原文的temporary对应，decrease与原文的decreased frequencies相对，故D项符合原文意思，为正确答案。
