In each set of sentences, one sentence is ungrammatical and three sentences are grammatical. First, select which sentence is ungrammatical. Second, explain why your chosen sentence is ungrammatical and describe the differences between the remaining 3 sentences in terms of meaning or grammatical function in the text box. 

Please note, there may be multiple ways to write your explanation although you will see only one option after you submit each response. Compare your explanation to the one provided and determine if one is more effective.

You must respond to each question before the AGG response will be displayed. After you submit each response, you will see the AGG response, but you won’t be able to see your response until the end. After the quiz, you will be able to review the summary of responses including the original sentence, your own response and the AGG revision. This quiz has 8 questions.

  1. She's bought snack.
