Question

yana is in the school computer lab writing a paper for history class. the graph represents the number of words yana has written after a number of minutes. history paper progress (graph with words typed on y - axis and time on x - axis, showing a line that rises, plateaus, drops, then rises again) which situation could describe yana’s activities in the computer lab?

• yana opened her saved paper, wrote, took a break, deleted some of the words, and then began writing again.
• yana began writing a new paper, deleted some of her words, took a break, and then began writing again.
• yana opened her saved paper, deleted some of her words, began writing, and then took a break.
• yana began writing a new paper, took a break, and then deleted some of what she had written.

Explanation:

Step1: Analyze the graph's trend

The graph starts with a non - zero number of words (so she opened a saved paper, not started a new one), then increases (writing), then plateaus (break), then decreases (deleting words), then increases again (writing again).

Step2: Evaluate each option

• Option 1: Matches the trend: opened saved paper (non - zero start), wrote (increase), took a break (plateau), deleted some words (decrease), then began writing again (increase).
• Option 2: Starts with new paper (should start at zero), so incorrect.
• Option 3: The last part is a break, but the graph after decrease increases, not plateaus, so incorrect.
• Option 4: The last part is deletion, but the graph after break decreases then increases, not just deletion, so incorrect.

Answer:

A. Yana opened her saved paper, wrote, took a break, deleted some of the words, and then began writing again.
