Q35 Second, because only male deer rub, the buck rub and its associated chemicals indicate the sex of the deer producing the rub. Third, older, more dominant bucks produce more buck rubs and probably deposit more glandular secretions on a given rub. Thus, the presence of many well-marked rubs is indicative of older, higher-status males being in the general vicinity rather than simply being a crude measure of relative deer abundance in a given area. The information conveyed by the olfactory signals on a buck rub make it the social equivalent of some auditory signals in other deer species, such as trumpeting by bull elk. What can be inferred from paragraph 4 about the trumpeting of bull elk? A. Trumpeting by higher-status bull elk signals their presence to other member of their species. B. Bull elk need to combine trumpeting with olfactory signals to convey information about their identify. C. Trumpeting alerts white-tailed deer to the presence of bull elk in their vicinity. D. Trumpeting provides a better measure of deer presence in a given area than buck rubs do. 此題答案為A，雖然看起來只有A最能選，但回來請教一下板上大大們，定位trumpeting of bull elk到最後一句，並往上找，找到『higher-status males being in the general vicinity rather than simply being a crude measure of relative deer abundance in a given area』以及接下來的『The information conveyed by the olfactory signals on a buck rub make it the social equivalent of some auditory signals in other deer species』第一個Quote是說這些如上所述的buck rub是由高階層的公鹿留下而非普羅大眾公鹿，第二個Quote是說這些資訊述說嗅覺信號與其他鹿種的聲音信號一樣，都提供了 social equivalent， social equivalent的意思不是讓鹿的社會平等，不分高低階層嗎？為何會出現A這種選項啊？ -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 140.112.25.103 ※ 文章網址: https://www.ptt.cc/bbs/TOEFL_iBT/M.1426755081.A.342.html
