The exercise below requires you to construct a sentence containing one or more ed-claused by modifying one or more sentences and by following the instructions carefully. Remember that a restrictive (defining) ed-clause does not require a comma whereas a non-restrictive ed-clause does.
You can copy and paste from the question to the answer window but be careful to remove any unnecessary words and be careful with punctuation (especially commas where a non-restrictive ed-clause is required).
You can make as many attempts as you wish for each question, but each attempt is only counted if your submission is close to the correct answer. After five close attempts you will have the option of seeing the correct answer. By clicking on the red square you can see further feedback about the correct answer. You will be able to see your quiz statistics (correct answers and number of attempts) once you have attempted all ten questions.
