Q. In which story is the answer to the question

0

?

\newline

Choices:

\newline

(A) Darren visited Denmark last year and participated in a polar plunge, a challenge where people jump into icy cold seawater! On the day of the challenge, the temperature in the air was

-10^\circ\text{C}

. Darren jumped into the water, which had a temperature of

10^\circ\text{C}

. How much warmer was the water than the air?

\newline

(B) Darren visited Denmark last year and participated in a polar plunge, a challenge where people jump into icy cold seawater! On the day of the challenge, the temperature in the air was

-10^\circ\text{C}

. Darren jumped into the water, which was

10^\circ\text{C}

warmer than the air. What was the temperature of the water?

Calculate Temperature Difference: Solve the first story, the question asks how much warmer the water was than the air. $\newline$ Calculation: $10\degree C - (-10\degree C) = 20\degree C$
Calculate Water Temperature: Solve the second story, the question asks for the temperature of the water. $\newline$ Calculation: -10\degreeC + 10\degreeC = 0\degreeC
Identify Correct Answer: Determine which story's question results in an answer of $0$ . In the first story, the difference in temperature is $20^\circ\text{C}$ . In the second story, the temperature of the water is $0^\circ\text{C}$ .
