参考答案
正确答案：A
解析：根据题干关键词why，a few sprays定位到第五段：...they didn't overdo it with the Windex, just a few spritzes—so we can get rid of brain-cell death or poisoning-induced generosity as reasons why...可知实验中科研人员并没有在屋子里喷很多的Windex香水，而是仅仅喷了几下，这样就能排除下面两个因素——(香水过量导致的)大脑细胞死亡、气味中毒导致的慷慨——从而更精确地评估香味对人的举止的影响。A)项符合文意。
