Explanation:

Question 7 (Matching)

Assuming typical contour line logic (higher elevation is "up"), if Location X is matched to 3000 and Location Y to 3500 (or vice versa, but let's assume standard mapping where higher numbers are higher elevation). If X is 3000 and Y is 3500, then X (3000) to Y (3500) is uphill. But the matching is likely: Location X - 3000, Location Y - 3500 (or reverse, but need to see the map's contour trend, but generally, higher numbers are higher elevation). So the matching would be Location X → 3000, Location Y → 3500 (or if X is higher, then X→3500, Y→3000, but the next question about walking from X to Y will clarify).

Question 8 (Multiple Choice)

To determine uphill/downhill, we compare elevations of X and Y. From the matching (assuming X is 3000 and Y is 3500, or X is 3500 and Y is 3000). If X is 3000 and Y is 3500, walking from X to Y is uphill (since 3500 > 3000). If X is 3500 and Y is 3000, it's downhill. But the next question (Q9) has 2500 as an option, so likely the contour interval is 500 (3000 - 2500 = 500, 3500 - 3000 = 500). So if X is 3000 and Y is 3500, then X to Y is uphill. So the answer is "Uphill".

Question 9 (Multiple Choice)

The lowest elevation contour line. The options are 2700, 2600', 2499, 2500. Contour lines are usually at regular intervals (like 500 here, since 3000 - 2500 = 500). The lowest should be the smallest number that fits the interval. 2500 is a multiple of 500 (2500, 3000, 3500...), while 2499 is not a clean interval, 2600 is not a multiple of 500 (if interval is 500), 2700 is also not. So the lowest is 2500.

Question 8 Answer:

Compare elevations of X and Y. If Y has higher elevation (e.g., 3500 vs X's 3000), walking from X to Y is uphill.

Contour lines follow regular intervals (e.g., 500 here: 2500, 3000, 3500). 2500 is the smallest valid contour elevation among options.

Answer:

B. Uphill (assuming the option labels: let's confirm the options as given: "Uphill" is an option, so the answer is the option with "Uphill".)
