I used lead and deadly as the ambiguities because they both can have different meaning. But I'm not sure how to explain how they can have different meaning in this sentence and how to restructure this sentence to make it right.
"Consider the sentence, "Diabetes can lead to deadly heart problems." Identify and explain any two ambiguities associated with the sentence."
English is a very sloppy language. There are many ambiguities in the statement. Some of them are more obviously absurd than others.
If you're interested in this kind of thing, I recommend studying the grammar of the constructed language Ithkuil, which is really precise about lots of things which English simply leaves to context.
