wanted to bring up 2 things to your attention regarding C
first, "dieting" is different from "diet" -> one may take "dieting" is as restricting yourself from certain foods as it isn't clear whether the gerund implies an action or a thing (diet)... I battle with these gerunds all the time
and love it... where is mailtheguru???
second, "WILL"..., courtersy of MGMAT SC
, should only be used when the outcome is 100% certain... do we know that it's certain??? what does one consider proper diet, etc... very ambiguous, so "WILL" changes the meaning of the sentence.... this point is supported by the OA choice D, which I believe is wrong for SVA
hope some of you agree
