Also, had they of done research on wills and added fact based information, than this would have made a crucial impact.
Is the writing after "Also" a restritive or nonrestrictive phrase?
I think that what is after "also" is restrictive but what is after the comma is nonrestrictive. Am I right?
The base material is "this would would have made a crucial impact", and the material before is essential (restrictive).
Here's a better way to write that sentence:
Also, if they had done research on wills and added fact-based information, then this would have made a crucial impact.
However, "this" doesn't seem to have any antecedent -- it's not clear in this particular sentence what "this" is.
