7. What is a sentence fragment missing

These lines reveal Silas as a quiter and unfaithful, careless and with a false pride.

Explanation:

The plot is supported as he is found asleep beside the stove, he comes back when he needs money for tobacco in the winter when Warren and Mary don't need the help, but when they do need help Silas leaves, so Warren is done, disappointed, frustrated, Silas is taking advantage of him, and Warren doesn't care if he's young or old-he didn't do his job and that's all that matters.

Mary doesn't want to hurt Silas' feelings, but Warren knows that Silas needs to learn a lesson, and Mary and Warren don't just have the extra money to give Silas.
