OG #24 [Possesive noun + gerund issue]

[bahuguna.priyank]

[deleted because problem is from a banned source - see below]

This question is pretty straight forward . but my doubt is
As per OG 12 "The -ing form of a verb can be used as noun (eg.,running is her favourite sport ) , but it is often awkward ,particularly when used with a possesive, as in this case ".

The aforementioned explanation conflicts with the Manhattan Flash Card of Sentence correction.

Please provide inputs on this

what specifically do you think conflicts between the explanation you've given and what's on the flash card? perhaps you can share the text on the flash card so we can discuss it further..
