Answer 1

To solve the problem, we can follow these steps:

1. Start with the initial temperature: 63°F.
2. The temperature drops by 10°F:
\[
63°F - 10°F = 53°F
\]
3. Then the temperature rises by 6°F:
\[
53°F + 6°F = 59°F
\]

Now the current temperature is 59°F. To find out how much the temperature needs to change to return to 63°F, we calculate the difference:
\[
63°F - 59°F = 4°F
\]

Therefore, the temperature needs to rise by 4°F to return to the initial temperature of 63°F.

So the correct response is:
**Rise 4 °F**.
