I found a question in the Peterson's Toolkit 2005:
"To relieve anxiety, moderate exercise can be equally effective as, and less addictive than, most sedatives"
The Correct response was
as effective as, and
but "equally as effective as, and" does not sound idiomatic to me.
For me, the correct choice is
effective, and
Could you please comment on this?
As far as I am concerned, if the first response were to be correct, the difficulty level of the question would be lot higher than what it would be if the second response were to be correct. (Is this sentence correct? I dont think both alternative can be subjunctive:) )
Thanks
