2.从句倒装，
derive 是 alphabets的动词
后半句还原为正常顺序后应该是both the northern and southern Indian alphabets derive from which(指代前面的te Aramaic script）所以动词不可以加s
derive为何不用一般过去时？因为是客观事实，比如下面的例句？medieval physicians were the first to discover that blood circulates through the human body
“which"指代the aramaic script, 那么需要有一样东西derive from the aramaic script.
since that something doesn't precede the verb 'derive', it must follow the verb 'derive'.
以及虽然it看起来是指代empire,可这个指代真是谜一样令人费解。
2.从句倒装，正常语序是alphabets were derive from
定语从句的结构，这里（from which）was derived ()alphabets,可以看出前方是个状语，然后是谓语动词，缺少主语，正常考虑应该是这里倒装了，向后寻找主语为alphabets，则前面的谓语动词为derive，选择C。
倒装的本质是谓语动词找不到主语，主语为紧跟在谓语动词之后的名词
if you use "the", then you're talking about THE alphabets, i.e., all of them.
