Explanation / Answer

11. The most probable option is b) when you don't have the appropriate permission to read the data.

13.The correct option is a) Source tab where you can view the coordinate system of the layer.

18. An increase in the length dimension (L1 or L2 or L3) will cover lesser part of the land. The areal extent of the features can be placed in the following order:

Woodland > Mountain > Highway.

Thus, for a highway, the best geographic representation is L3, as the feature will be the smallest on a map of 1:50,000 scale.

For a woodland, the best geographic representation is L0, as the feature will be the biggest on the map.

For mountains, the best geographic representation is L1, as the feature will be much bigger than the highway but a bit smaller than the woodland.
