Explanation:

To determine what the line plot will show, we analyze each option:

• "whether Debra’s brother improved each week": A line plot can show trends over time, so it can indicate improvement (increase in correct answers) each week.
• "the lowest number of correct answers": A line plot of weekly correct answers will display individual data points, so we can identify the minimum (lowest) value.
• "the total number of weeks": The line plot's x - axis (if weeks are the independent variable) or the number of data points can show the total number of weeks (since each week is a data point).
• "the number of times Debra’s brother got 40 out of 40 correct": A line plot of weekly correct answers will have a data point for each week, so we can count how many times the value is 40.

Answer:

A. whether Debra’s brother improved each week
B. the lowest number of correct answers
C. the total number of weeks
D. the number of times Debra’s brother got 40 out of 40 correct
