OG876题我想了很一会，放在这里做个记录：
Yellow jackets number among the 900 or so species of the world's social wasps, wasps living in a highly cooperative and organized society where they consist almost entirely of females-the queen and her sterile female workers.
Awasps living in a highly cooperative and organized society where they consist almost entirely of
Bwasps that live in a highly cooperative and organized society consisting almost entirely of
Cwhich means they live in a highly cooperative and organized society, almost all 分析该选项
Dwhich means that their society is highly cooperative, organized, and it is almost entirely
Eliving in a society that is highly cooperative, organized, and it consists of almost all
答案是B，OG说平行推出来的我能理解，但是没明白为什么前面还跟了一个wasps，难道不是上一个句子最后有wasps了吗？
曼哈顿论坛上ron给出了以下答案：
your analysis of choice a is 100% correct. choice b features a rather strange-looking usage of a very common construction: the use of an appositive phrase (a noun phrase with no introductory words) to define a term, in this case 'social wasps'.
here's an example:
seamen distinguish flotsam, goods floating on seawater after a shipwreck from jetsam, goods thrown overboard by the crew of a ship.
you've probably seen this construction many times. it's weird-looking in this problem, though, because of the apparent repetition of 'wasps'.
but here's the story: the term being defined is 'social wasps'.
therefore, there's actually no redundancy: you need to think about 'wasps' and 'social wasps' as two completely different words. once you think about it that way, the sentence is just like the flotsam/jetsam example above, which should be noncontroversial.

补充一下appositive phrase的意思：
An appositive phrase is a noun phrase that identifies or renames another noun phrase directly before or after it. For example, you might say, “I’m going to see my dentist, Dr. Parkins.” In this case, “Dr. Parkins” is an appositive phrase because the name identifies exactly who the dentist is. The two phrases are said to be “in apposition,” and the one that does the renaming or identifying is called the appositive phrase.
The definition of appositive is such that an appositive phrase can come anywhere in a sentence, at the beginning, middle, or end. You can see this in the following example (appositives in bold): - The fastest man ever timed, Usain Bolt is competing in Rio this summer.
- Usain Bolt, the fastest man in the world, is competing in the Brazil Olympics.
- Olympic spectators are looking forward to watching Usain Bolt, the Jamaican sprinter.
=========================
另外ron神还在下面说了一个经验，觉得说的很有道理：永远不要质疑OG的正确答案！这也是分析OG的一个重要的点！
DO NOT, EVER, UNDER ANY CIRCUMSTANCES, QUESTION THE CORRECTNESS OF AN OFFICIAL ANSWER TO AN OFFICIAL PROBLEM. the official answers are always correct -- even in cases when we moderators find them ugly and repulsive. if something is in an official answer, it's correct. end of story. period. so: THE WRONG QUESTION TO ASK: "isn't (---thing that's in official answer---) wrong?" you already know the answer to this question: "no, it's not wrong; it appears in the official answer." THE RIGHT QUESTION TO ASK: "WHY is (---thing that's in official answer---) CORRECT? HOW does that WORK?" note the big difference between these questions. the first one is a question to which you already know the answer, and which will get you nowhere in your studies. the second, on the other hand, is a constructive question whose answer will invariably expand your SC knowledge.
