Correct Option: B. 800m Detailed Explanation: To determine the highest point in the area depicted on the map, we need to analyze the elevation data provided. Here’s a step-by-step breakdown of how to arrive at the correct answer:

1. Understanding Elevation: Elevation refers to the height of a point above sea level. In geographical maps, elevation is often indicated using contour lines, spot heights, or shading.
2. Interpreting the Map:
3. If the map includes contour lines, these lines connect points of equal elevation. The closer the lines are to each other, the steeper the terrain.
4. If spot heights are indicated, they will show specific elevations at certain points on the map.
5. Identifying the Highest Point:
6. Look for the highest contour line or the highest spot height on the map.
7. If the map has contour lines, the highest point will be at the peak of the highest contour line. If there are spot heights, the highest number will indicate the highest elevation.
8. Comparing Options:
9. The options provided are 900m, 800m, 700m, and 600m.
10. By examining the map, we find that the highest elevation indicated is just above 800m, which means it is likely around 800m but not reaching 900m.
11. Conclusion:
12. Since the highest point is just above 800m, the correct answer is B. 800m.

Why Other Options Are Incorrect:

• Option A: 900m: This option suggests that the highest point is at or above 900m. However, if the highest elevation on the map is just above 800m, then this option is too high and does not accurately reflect the data presented.
• Option C: 700m: This option is lower than the highest point identified on the map. Since we established that the highest point is just above 800m, this option is not valid.
• Option D: 600m: Similar to option C, this is significantly lower than the highest point. The highest elevation is above 800m, making this option incorrect.

Common Pitfalls:

• Misreading Contour Lines: Students often misinterpret the spacing of contour lines, which can lead to incorrect conclusions about elevation.
• Ignoring Spot Heights: If spot heights are present, they should be prioritized over contour lines for identifying specific elevations.
• Assuming Without Checking: Always verify the highest point by checking all available data on the map before selecting an answer.

Revision Summary:

• The highest point on the map is just above 800m, making option B the correct choice.
• Always analyze contour lines and spot heights carefully to determine elevation.
• Compare the highest point with the provided options to ensure accuracy.
• Avoid common pitfalls by double-checking your interpretation of the map data.
