I am uneasy with "in paying" and "its payment" and want to try to explain.
in most of the cases, "doing" is associated with the creator of "doing" already" and this pattern is concise and nor redundant. for example
I get good knowledge in learning gmat.
I learn gmat, making my knowlege better.
in all 2 cases, which are similar to the choice E, the creator of "doing" is clear and we should not use possessive+noun which can be wordy or reduntant.
some persons even think pessessive+doing is flat out incorrect when the noun of doing exists.
is my thinking correct?
