Question

jordan is visiting an exhibit on the third floor of a museum. after viewing the entire exhibit, he takes the elevator to the fifth floor and looks around for a while. then, he goes down to the cafeteria on the ground floor for lunch. which graph could show jordans height above ground level over time?

Explanation:

Step1: Analyze Initial Height

Jordan starts on the 3rd floor, so initial height is non - zero and constant while viewing the exhibit.

Step2: Analyze Movement to 5th Floor

He takes elevator to 5th floor, so height increases (a vertical or sloped line up, but since it's elevator, we can consider the change in height over time; here, the key is the height goes from 3rd floor height to 5th floor height, so a jump or a line up). Then he stays on 5th floor, so height is constant (horizontal line).

Step3: Analyze Movement to Ground Floor

He goes down to ground floor, so height decreases to zero (a line down to y = 0).
Looking at the graphs:

• Top - left: Starts at non - zero, increases (to 5th floor from 3rd? Wait, no, initial height is 3rd floor, then goes to 5th (higher), then stays, then goes down. Wait, the top - left: first, height is increasing (but initial height is 3rd floor, so maybe the first part is viewing on 3rd (constant), then up to 5th (increase), then constant, then down. Wait, the bottom - left graph: first, constant height (3rd floor), then jumps up (to 5th floor), then constant (viewing on 5th), then down to ground (height 0). Let's check each:
• Top - left: The first part is increasing, but he starts on 3rd floor (should be constant first). So no.
• Top - right: The height is constant, then jumps up, then constant, then down? Wait, no, the top - right has a vertical line, but the bottom - left: first, horizontal line (constant height, 3rd floor), then vertical line up (to 5th floor), then horizontal line (staying on 5th), then vertical line down (to ground). That matches: view on 3rd (constant), elevator to 5th (height increase, vertical line as time passes but height jumps), view on 5th (constant), elevator to ground (height decrease to 0, vertical line). Wait, but maybe the movement is with time, but in terms of the graph, the bottom - left graph: first, height is constant (viewing on 3rd), then height increases (to 5th), then constant (viewing on 5th), then height decreases to 0 (going to ground). Wait, the bottom - left graph's first segment is horizontal (constant height), then vertical up (height increase), then horizontal (constant), then vertical down (height 0). That matches the sequence: 3rd floor (constant) -> 5th floor (height up) -> stay (constant) -> ground (height down to 0).

Answer:

The bottom - left graph (the third graph, if we count top - left, top - right, bottom - left, bottom - right as 1,2,3,4) or the graph in the bottom - left of the four graphs.
