Explanation / Answer

Answer:

1. The answer is a) LIKE. When building expressions for the Query Attributes task, the LIKE operator can be used to make string comparisons.

2. The answer is a) Union. It includes all the polygon parts in either or both A and B. So, it is the sum of all the parts of both A and B.

3. The answer is d) dissolve. This tool combines features based on a specified attribute.

4. The answer is c) graduated symbols. The graduated symbols, unlike unclassed proportional symbols, are class ones and represented by squares of increasing size according to increasing data value.

5. The answer is a) intersection. It combines all the features common in feature classes.
