thanks Mike,
so glad to get your reply

Examples:
This is my friend who he wrote a book. = double subject
This is the book that I read it. = double direct object
This is my friend to whom I lent the book to him. = double indirect object
This is more that simply a matter of concision. This is egregiously wrong, and wrong 100% of the time.
these examples are easier to understand,
BTY, can I view these examples as redundant? as my thought in the first thread.

What I really want my friend
zoezhuyan to understand that this very specific version is a completely clear rule, but because these sentence all would sound gratingly wrong to native ears, something of this sort never would be tested on the GMAT. The GMAT excels at creating wrong versions that sound plausible to native ears. That's the paradox about grammatical rules. The grammar rules that are the clearest are (a) extremely specific, and (b) so obvious to native speakers that the GMAT would never test it.

Mike, this is a simple version from OG16, SC # 103, the original version is :
Nobody knows exactly how many languages there are in the world, partly because of the difficulty of distinguishing between a language
and the sublanguages or dialects within it, but those who have tried to count typically have found about five thousand.
(A) and the sublanguages or dialects within it, but those who have tried to count typically have found
(B) and the sublanguages or dialects within them, with those who have tried counting typically finding
(C) and the sublanguages or dialects within it, but those who have tried counting it typically find
(D) or the sublanguages or dialects within them, but those who tried to count them typically found
(E) or the sublanguages or dialects within them, with those who have tried to count typically finding
when I read the explanation of C from OA,
OA
The second appearance of it, referring to world languages, is incorrect because it does not agree in number with languages.
an question occurred in my mind, according to this explanation, I got an idea that pronoun in modifier of 2nd sentence is correct, in other hand, a pronoun in modifier is acceptable if no redundant,
then I should change my former idea that pronoun in modifier is always incorrect is incorrect,
I was not sure whether it is the test point, so posting the topic to implore confirmation.
have a nice day
