Please refer to the following for having the concept clear:
(i) Refer to OG 11
(ii)Refer to the explanation from webster logs below - I hope it WILL make the answer clear (http://webster.commnet.edu/grammar/gram ... ogs426.htm
Which of the following is correct? I have found conflicting responses in style and grammar reference books.
Based on our research, additional testing is not necessary.
On the basis of our reasearch, additional testing is not necessary.
(According to most books, two (2) is correct, but it sounds wordy, and my grammar check always flags it. In one (1), "based on" is a dangling modifier; it is not an absolute participle. Therefore, it is wrong.
Which is NOW most acceptable. I really want to use one (1). It just sounds tighter, more concise.
In either case, you have a modifier â€” either (1) a participial phrase or (2) a prepositional phrase â€” trying to modify something it can't really modify, "additional testing." Can't we write something like, "On the basis of our research, we feel that additional testing is not necessary"? Or "Our research indicates that additional testing is not necessary"? If that still sounds wordy to you, I vote for your #2, as the dangling modifier in #1 makes it sound as if "additional testing" is "based on our research," which isn't true.
