Final answer:
The correct answer is option A. The dialogue likely indicates that Alexis' mom does not realize she has been at the computer for a long time, as the surrounding context shows she is overwhelmed and busy with many responsibilities.
Step-by-step explanation:
The dialogue by Alexis' mom, as presented in the various excerpts, does not indicate that she feels pressured to finish her work at the computer, is just about to stop working and make dinner for Alexis, or that she had just recently taken a break from the computer.
Instead, the collective context of these passages suggests that Alexis' mom is tired and potentially overwhelmed by her circumstances, which include dealing with her own busy schedule, her second language limitations, and a lack of resources like a home computer and printer. Given this context, the dialogue might be interpreted to convey that Alexis' mom does not realize she has been at the computer for a long time, as the pressures and distractions of her situation seem to consume her attention and time.
