What do you change so that the headline means "an expert on canine education will offer remarks" rather than "area doge is now giving English classes to scientists abroad"? Dog teaching expert to speak.
A. Change teaching-VBG (verb gerund) to teaching-NN (noun).
B. Change speak-VB (verb) to speak-NN (noun)
C. Change dog-NNP (proper noun) to dog-VB (verb)
D. No changes necessary; this is a case of semantic, rather than syntactic ambiguity.
