(D) only one of eight Revolutionary War battlefields to remain undeveloped（A）

标准答案是A, 没有异议.

但我认为only前面应该有the, 因为后面跟了限定性修饰, 表明特指. 就象OG里的两个例子:

答案是比较出来的, 除了A, 其他的错误因该说是明显的.

the的问题, 我是这样看, 首先好像即使要加, 也要说成the only one of, 这样才idiomatic.

大全中的这题, 这里的only已经起到了限定的作用, 所以再用the感觉是重复的, 而且费话一句, 这种细枝末节的语法点太难以掌握, 不要太看重.
