Read this paragraph. Click on each sentence that is a fragment. Then choose the complete sentence that fixes each fragment. In some cases, the new sentence will combine two sentences. When you have fixed all the fragments, click DONE to check your work.

<Each fragment, when clicked, should reveal a pop-up that allows user to select one of two sentences. The selected sentence should then replace the fragment in the paragraph (and remain highlighted in some way). Until the DONE button is clicked, user should have the option of clicking each highlighted sentence again and choosing the other answer.>
