Question

one important and unavoidable source of bias in maps is:
a. the decision about what to include and exclude.
b. the decision to make a map in the first place.
c. the type of paper used.
d. the resolution for lines of longitude.

Explanation:

When creating a map, the cartographer must decide what information to include (e.g., roads, landmarks) and what to exclude (e.g., minor paths, less - significant features). This selection process inherently introduces bias as different choices can emphasize or de - emphasize certain aspects of the mapped area. Making a map (option B) is a neutral decision. The type of paper (option C) and longitude line resolution (option D) do not relate to bias in map content.

Answer:

A. the decision about what to include and exclude.
