The temperature needs to fall 4℉ to return to the initial temperature of 64℉.
To return to the initial temperature of 64℉, we need to reverse the changes that have occurred.
Given that the temperature dropped 7℉ and then rose 11℉, the net change in temperature is -7℉ + 11℉ = 4℉.
Therefore, the temperature needs to rise by 4℉ to return to the initial temperature of 64℉.
So, the correct answer is: Rise 4℉.
To determine how much the temperature needs to rise or fall to return to the initial temperature of 64℉, we need to track the temperature changes.
Given that the temperature initially was 64℉ and then dropped 7℉, the temperature would be 64 - 7 = 57℉.
Now, if the temperature rises 11℉ from 57℉, we would add 11℉ to 57℉, resulting in a temperature of 57 + 11 = 68℉.
To calculate how much the temperature needs to rise or fall to return to the initial temperature of 64℉, we subtract 64℉ from 68℉: 68 - 64 = 4℉.
So the correct answer is: Fall 4℉.
