OA : A

How to figure it out whether "research subject / research subjects" is correct.Also, what "it" refers to in the sentence.

well as i said i somewhere not able to digest this SC
research subject / research subjects can be contending points
let some expert tell us more on this one

as for "it" ---> which "it" u referring .

I feel the question is not adhered to GMAT standards.
"Myriad Genetics feels it is entitled to its patent on"

Two verbs are not connected properly. Myriad genetics feels that it is entitled.

Guys some light on this ? It is a runon sentence ?
