Explanation:

The given question refers to an Accuplacer reading practice test about two teenagers who decide to steal from a local bodega.

This is the beginning of the test:

As Marie placed her hand on the cold handle of the door, she felt a chill run through her body. Her parents would be home soon, wondering where she was, but this was something she had to do. She looked back at Jessica, who only yesterday was mocking Marie in front of their classmates for her braces and good grades, and thought she saw a hint of worry on Jessica’s face. If it had been worry Marie saw on Jessica’s face, it was quickly gone, replaced with a steely stare that shoved Marie through the door and into the bodega.

The options you were given are the following:
