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.
請問og劃線部份是什麼意思@@?
to sign為什麼是noun equivalant?
