og24的疑点

24. The first decision for most tenants living in a building undergoing being converted to cooperative ownership is if to sign a no-buy pledge with the other tenants.

(A)  being converted to cooperative ownership is if to sign

(B)   being converted to cooperative ownership is whether they should be signing

(C)  being converted to cooperative ownership is whether or not they sign

(D)  conversion to cooperative ownership is if to sign

(E)   conversion to cooperative ownership is whether to sign

In A, B, and C, the phrase being converted is awkward and redundant, since the sense of process indicated by being has already been conveyed by undergoing. A and D can be faulted for saying if rather than whether, since the sentence poses alternative possibilities, to sign or not to sign. Only E, the best choice, idiomatically completes whether with an infinitive, to sign, that functions as a noun equivalent of decision. Choice E also uses the noun conversion, which grammatically completes the phrase begun by undergoing.

这里to sign 作为名词是什么语法现象？能给个例子吗？

这是BE前后的对等. Og-17: Residents were part of culture.

undergoing conversion是什么意思呢?

The first decision for most tenants living in a building undergoing。。

请问这里的undergoing是修饰buliding还是修饰tenants？

修饰building

but could you tell me what does  the sentence mean?

对于住在一栋楼里的正在经历与（和他们协作的）房主谈判的大多数的房客来说，他们的第一个决定就是是否与其他房客签订不买卖的保证
