White rhinoceroses, 11 , do the same thing—only their choice of meeting place is a giant pile of poop.
答案：(B) it turns out
it turns out 作插入語，意為「結果發現、原來」，用來帶出出乎意料的事實——白犀牛竟然也和人類一樣會聚集交流；what is more（更有甚者）、in other words（換句話說）、all in all（總而言之）都不帶「意外」的語氣。
答對率 29%。
turn out 你記得的大概是「結果變成」（It turned out to be a great success.）或「出席、到場」（A large crowd turned out.），很少看到它以 it turns out 的形式夾在句子中間當插入語。這個用法等於中文的「結果發現…」「原來…」，專門用來帶出出乎意料的事實。
前一句 From the campfire to the café, people have always gathered together to share the latest news.（從營火到咖啡館，人類一向聚在一起分享最新消息）講的是人；本句話鋒一轉講白犀牛 do the same thing（也做同樣的事），這在讀者預期之外，所以需要一個標示「意外」的插入語。要判斷這一格，必須回頭讀前一句，屬於跨句題。
what is more 用於「再加一項同方向的資訊」；in other words 用於把剛才說過的話換句話說；all in all 用於總結收尾。三者都不帶驚訝的語氣，而本句 only their choice of meeting place is a giant pile of poop（只不過牠們挑的聚會地點是一大坨糞便）明顯是在製造反差趣味。
國中學過 It turns out that…（結果發現…），本題只是把 that 子句改寫成插入語形式，語意完全相同。
it turns out (that)…（結果發現）、turn out to be（結果是）、what is more（更有甚者）、in other words（換句話說）、all in all（總而言之）。
From the campfire to the café, people have always gathered together to share the latest news. White rhinoceroses, 11 , do the same thing—only their choice of meeting place is a giant pile of poop. A new study indicates that rhinos have a smelly way to 12 .
Scientists studying white rhinos in South Africa have found that these animals leave messages in their poop. In particular, they leave their poop in the same place for all the other members in the group to smell—just like humans leaving messages on social media. Furthermore, different rhinos leave different chemicals in their poop, which provide important 13 about the age, sex, general health, and reproductive conditions of each specific rhino.
This is of great significance for the peace and harmony in the group. When all members in a group know what's going on with each other, it is 14 that they will fight.
The researchers have even made "fake poop" to see how different rhinos would react. They find that dominant males are particularly 15 the "fake poop" that carries chemicals from females ready to mate. The males sniff it for longer duration and come back to the same spot more frequently, a clear sign that they are gathering information about mating opportunities from the poop.
