Guys, thanks for all your contributions. I've figured out.
The explanation in #49 in diagnostic test in
OG 12th ed says it all:
49. As an actress and, more importantly, as a teacher of acting,
Stella Adler was one of the most influential artists in the American theater, who trained several generations of actors including Marlon Brando and Robert De Niro.
(A) Stella Adler was one of the most influential artists in the American theater, who trained several generations of actors including
(B) Stella Adler, one of the most influential artists in the American theater, trained several generations of actors who include
(C) Stella Adler was one of the most influential artists in the American theater, training several generations of actors whose ranks included
(D) one of the most influential artists in the American theater was Stella Adler, who trained several generations of actors including
(E) one of the most influential artists in the American theater, Stella Adler, trained several generations of actors whose ranks included
" Several generations of actors including" shows the same error
in reverse; "including" modifies the whole phrase, but the two actors named are not generations of actors. The more limiting clause whose ranks
included (referring to actors) is appropriate here.
so this means GMAC thinks that the phrase "including x" can modify the whole phrase preceding it.
This means that for any pattern like this "is a member of the generally toxic nightshade family, including belladonna." the "including belladonna" is modifying "a member of the generally toxic nightshade family" which doesn't make sense
The post offered by dreambeliever can testify to this rule:
The new image of Stone Age people as systematic hunters of large animals, rather than merely scavenging for meat, have emerged from the examination from the examination of tools found in Germany, including three wooden spears that archaeologists believe to be above 400,000 years old.
A
B. as mere scavenging for meat, have emerged from examining tools found in Germany, which include
C. as mere meat scavengers, has emerged from examining tools found in Germany that includes
D. mere scavengers of meat, has emerged from the examination of tools found in Germany, which includes
E. mere scavengers of meat, has emerged from the examination of tools found in Germany, including
OA is E, indicating that "including..." is modifying the whole phrase "tools found in Germany"
