On a given morning the temperature was 71°F. The temperature dropped 5°F and then rose 8°F. How much does the temperature need to rise or fall to return to the initial temperature of 71°F?
A) Fall 8°F
B) Fall 3°F
C) Rise 8°F
D) Rise 5°F
To return to the initial temperature of 71°F, the temperature needs to rise by the same amount that it dropped. Since the temperature initially dropped 5°F, it needs to rise 5°F to return to 71°F.
Therefore, the correct answer is D) Rise 5°F.
