yes, basically the same thing.Because if it means the former,then "what"and"it"in answer C means the same thing"the rate of increase of...."here.
not really --
consider the construction "the rate was X" (where X is a mathematical rate quantity).
in this case, the "what" corresponds most closely to the "X", while the "it" corresponds most closely to "the rate".I am really confused about the usage of "what" .
Please help me .Thanks!
your confusion is understandable.
when you learn constructions like this, which are highly specific from language to language, your best bet is probably to just learn the constructions wholesale -- i.e., don't try to dissect them excessively, as long as you can understand how they work.
for instance, consider the following:
i see a man, but i don't know who he is.
do you understand this construction?
i don't really know how to break it down grammatically, but i do know that it functions in precisely the same way as ...what it is.
the "who" is playing the same role as the "what"; "he" is playing the same role as "it". no redundancy.
THANKS RON!~
wonderful explanation!
I think I got what you mean.
to me,"what it is"is a rreally difficult structure.
hah,English is really different from my mother language.
thanks you again.
