Whereas scientists,because of random fluctuations in the weather,can not determine the transition from one season to the next by monitoring temperatures on a daily basis,so they cannot determine the onset of global warmming by monitoring average annual temperatures.
A.Whereas scientists
B.Just as scientists
C.Like scientists who
D.Inasmuch as a scientist
E.In the same way a scientist
正确答案选B
但是这里后面一句已经有了连词so，前面是不是不应该加东西了。我有点糊涂，哪些是并列句中可以同时使用的连词，哪些是状语从句和主句可以使用的连词~~请大家指教~~~

as作为连词表相似性，其用法为：
1.（just）as+从句，主句（与从句尽可能对称）
2.（just）as+从句，so+主句（与从句尽可能对称）
3.（just）as+从句，so too +主句（倒装）

本题是第二种用法，because of random fluctuations in the weather相当于插入语~
