I'm supposed to fill in the blank in the following sentence:
Herbicides used to clear railways and railway embankments are not selective ______ all plants with which they come into contact.
in the above sentence, the correct answer is "and kill".
But I want to know if "to kill" is correct too or not?
Do we have this structure: "be+selective+infinitive"?
in my view, "to kill" means "in order to kill all the things..."
"and kill" means "so they kill all the things..."
So both of them are correct!
