1) why B is wrong here
B is not correct on multiple counts:
1. B uses
encourage. We can interpret this in two ways:
a.
…its new scheme will support X and (its new scheme) encourage Y. This is not correct construction, since you would expect the verb to be
encourages (since
scheme is singular).
b.
…its new scheme can support X and (can) encourage Y. The issue here is more of logic. When Knowledge International (or anyone else for that matter) says something about its (own) scheme,
can comes out as too in-definitive and non-committal a statement (think about it: Fed says its measures
can improve US economy).
2. Changes the meaning of the original sentence, since
older is not the same as
mature.
p.s. I would strongly encourage test takers to
not interpret
would as
hypothetical usage. For example,
I will become a pilot is a correct usage, though at this point of time, it is still hypothetical (whether I finally end up becoming a pilot or not).
The best way to interpret
would is when one talks about
future from past perspective. In this case, Knowledge International said in the past (sentence, due to its typical construction, uses
says, but this act of saying clearly occurred sometime in the past) something about future (that its scheme
in future will do X and Y). Hence,
would is the most appropriate usage here.
