I have read from a previous post: What part of speech is "instructing ..." here?
1.The editor at once sent the journalist a telegram instructing him to find out the exact number of steps and the height of the wall.
The comment says,
"Instructing" is modifying the noun "telegram".
But how can we exclude the possibility that "instructing" takes "the editor" as its implied subject？
I think of another sentence:
2.Later he wrote me a letter apologizing for not lending me a hand.
"Apologizing" surely means "he apologizes".
So can we similarly understand that, in the first sentence, it is "the editor" that is instructing?
