Regarding Pulitzer problem:
my options in the picture seem different from the options posted by you on the post, that you have directed me to.
In your post 'for' is used in D option....which seems correct usage
In my posted pic, you will notice that D option uses a 'to' and E uses a 'for'
I went for 'e' for parallelism, But OA is D
Regarding Vine Growers problem:
For D option
Vine growers still harvest grapes as have been done for centuries (sounds awkard)
'has' is to be used as it refers to harvest
I dont find any problem with A. I just dont find any problem with D too. Kindly clarify
Regarding posting one problem in one post: Will take care of it in future
Success is a journey.....enjoy every moment of it
