Though there are few new words in the novel, I still can't understand it completely; ___ I am given ___, then I am sure I can make it.
A. but; time enough
B. / ; enough time
C. yet, enough time
Q: 第一个空yet为什么不行？
Clara: 在此，作为conj.，but 和yet 都可以表达转折这样的逻辑，但是二者还是有差别的。下面我们通过英英释义来帮助理解：
yet conj.
表示转折，意为“但是，然而”，往往含有“尽管如此但......”之意。
柯林斯：
You can use yet to introduce a fact that is rather surprising after the previous fact you have just mentioned. （用于引出颇令人惊讶的事实）可是却，却又
e.g: I don't eat much, yet I am a size 16.
我吃得并不多，但是却穿16码的衣服。
e.g: They were terrified James would die — yet there were moments when they almost wished he would.
他们很害怕詹姆斯会死——然而，有那么几个瞬间，他们几乎是希望他会死。
剑桥：
(and) despite that; used to add something that seems surprising because of what you have just said
e.g: He's overweight and bald, (and) yet somehow, he's attractive.
他肥胖且秃头，然而不知为何却很有魅力。
but conj.
but 作连词时，有多种用法，此处考拉仅引用适用于此题的用法。
柯林斯：
You use but when you are about to add something further in a discussion or to change the subject.
e.g: They need to recruit more people into the prison service. But another point I'd like to make is that many prisons were built in the nineteenth century.
监狱需要招募更多的工作人员。但我想补充一点，很多监狱都是在19世纪建造的。
剑桥：
used to introduce an added statement, usually something that is different from what you have said before
综上可见，but可以用于附加说明。
Though there are few new words in the novel, I still can't understand it completely; but I am given time enough (或enough time), then I am sure I can make it.
but I am given time enough, ......
不过，给我足够的时间的话，......
这个句子有含蓄的“条件”意味
这样比较好理解：
but given time enough, ...
或
but if I am given time enough, ...
