Here is, in observation of Labor Day 2018, a context clues worksheet on the verb exploit. It is apparently only used transitively. This is one of those words with some subtle connotations, so this document alone will probably not suffice to fully flesh them out.
If you find typos in these documents, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
