Hello Ron and all the other instructors,

About the OA choice (E), I have a question with the usage of "or".
Since the post has been long time ago, I'd like to repost the original question and the OA as below,

Heirloom tomatoes, grown from seeds saved from the previous year, only look less appetizing than their round and red supermarket cousins, often green and striped, or have plenty of bumps and bruises, but are more flavorful.

E. cousins; they are often green and striped, or have plenty of bumps and bruises, but they are

I thought "or" is a conjunction and its usage is the same as that of "and" and "but".
When a sentence is written with "comma+or", a whole sentence with S+V shall be precedent and followed after "comma+or".
However, in this OA choice, there's lacking of a subject after "comma+or". Why isn't it a sentence fragment ?

I know it's worthless to question the OA, but I just want to take the chance to correct my mindset with the usage of "or".

Thanks a million for your time and reply!!

i'm just noticing that this problem is from a banned source (scoretop). so, with all due apologies, we're going to have to lock this thread.
