Q. In which story is the answer to the question

0

?

\newline

Choices:

\newline

(A) Destiny went on an RV trip in South America. In the first week, she visited Laguna del Carbón, a lake with an elevation of

-344

feet. During the second week, she went camping near the Andes Mountains at an elevation that was

344

feet higher than Laguna del Carbón. At what elevation was Destiny camping?

\newline

(B) Destiny went on an RV trip in South America. In the first week, she visited Laguna del Carbón, a lake with an elevation of

-344

feet. During the second week, she went camping near the Andes Mountains at an elevation of

344

feet. How much higher was the elevation where Destiny went camping than the elevation of Laguna del Carbón?

Calculate Camping Elevation: Solve for the elevation where Destiny was camping in story (A). Calculate the elevation by adding the increase to the initial elevation. $\newline$ $(-344 \text{ feet} + 344 \text{ feet} = 0 \text{ feet})$
Calculate Elevation Difference: Solve for the difference in elevation in story (B). Calculate the difference between the camping elevation and the initial elevation. $\newline$ egin{equation}( $344$ \text{ feet} - ( $-344$ \text{ feet}) = $688$ \text{ feet}) $\newline$ egin{equation}
Identify Correct Answer: Determine which story's question results in an answer of $0$ . In story (A), the elevation where Destiny was camping is $0$ feet. In story (B), the difference in elevation is $688$ feet. So, the answer is story (A)
