Select the appropriate verbs from the drop-down menus to complete each sentence correctly. There are thirty-three "opportunities for error" in these paragraphs. When you click on "check answers," the computer will indicate your score and put a sideways grin :) next to each correct answer and an X next to any incorrect answers. Reconsider and change any incorrect responses; then re-grade the quiz. Caution: the singular verb is not always given first.
