Answer(s): A

Explanation:

Box 1: Merge
There are two primary ways of combining queries: merging and appending.
* When you have one or more columns that you'd like to add to another query, you merge the queries.
* When you have additional rows of data that you'd like to add to an existing query, you append the query.
Box 2: Disable the query load
Managing loading of queries
In many situations, it makes sense to break down your data transformations in multiple queries. One popular example is merging where you merge two queries into one to essentially do a join. In this type of situations, some queries are not relevant to load into Desktop as they are intermediate steps, while they are still required for your data transformations to work correctly. For these queries, you can make sure they are not loaded in Desktop by un-checking 'Enable load' in the context menu of the query in Desktop or in the Properties screen:
