OK, once again from the pages of Paul Brians’ book (to which he allows no-cost access at his Washington State University webpage) Common Errors in English Usage (he’s up to a third edition, I believe), here is a worksheet on the use of the plural nouns issues and problems. This is a full-page document with a six-sentence reading and ten modified cloze exercises.
As usual, Professor Brians promotes good usage by way of a short but punchy reading on the historical linguistics, so to speak, of these two words.
If you find typos in this document, 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.
