...from Robert Boyle forward...is not proper use
(who the hell writes/talks like that ?)
Well. I agree that E is clumsy 'cause of "his". But I dont know how to eliminate D
..Thank you for your patient!
So "since Robert Boyle" is correctly use. Actually it sounds strange to me.
OA is A
That sounds strange to me too
Nevertherless, A sounds the best here..
Could anyone explain the usage of "since Robert Boyle"?? Does it mean "the chemistry works done by Robert Boyle"? smth like that??
