这题类似OG中古希腊人食谱的那道题目。
划线与非划线部分讲的是两个完全不同的意思，句子的意思说的是主要原因是环境性的，而化学性的不平衡比较少见，所以，用and连接是不正确的。
as rare.中 rare有半生熟的意思，因此这个选项不正确。
D中缺少连接词与整个句子连接。
E中，用with连接，修饰the causes of mental illness

og上的第104题和这题类似：
The diet of the ordinary Greek in classical times was largely vegetarian---vegetables,fresh cheese,oatmeal,and meat cakes,(and meat raraly)
A,and meat raraly
B,and meat was rare
C,with meat as rare
D,meat a rarity
E,with meat as a rarity
答案为E，
解释：The best answer here must qualify the statement made in the main clause,The diet..was largely vegetarian:it can not be treated as part of the list of vegetarian foods.In other words, the best answer must logically and grammatically attach to the main clause when the list is omitted.
另外用rare有歧义，可能是熟的意思

rare是半生不熟的意思

rarity珍品,稀薄.根据句意就是吃少量的肉
用and前后形式不对称,C里AS+形容词不对,D没有连接词,意思也不对,E最好
