○ ed painted at a constant rate for the first two hours and then rested most of the third and fourth hours.
○ eds rate of painting increased throughout the four hours he painted the portrait.

Explanation:

Step1: Analyze Part A graph slope

The steeper the slope, the more painted. The first hour has the steepest slope, the fourth hour has the flattest slope (least progress).

Step2: Match Part A to options

Fill the blanks: most = first, least = fourth.

Step3: Analyze Part B graph trend

The curve starts steep, then gradually becomes less steep, meaning the rate of painting slows over time.

Step4: Match Part B to options

Select the statement that matches the decreasing slope trend.

Answer:

Part A:
Ed painted most of the portrait during the first hour, and he painted the least amount during the fourth hour.

Part B:
At first, Ed painted quickly, but his rate of painting continued to slow throughout the four hours.
