D. Addition of a new column to the Left Base Table
E. Assignment of a column alias

Answer 1

In the given query, FROM VEHICLE_TYPE VT INNER JOIN VEHICLE_INVENTORY VI represents the joining of two tables. It is used to determine the maximum and average MSRP for each distinct 'ModelName' from the two tables.

Step-by-step explanation:

In the given query, FROM VEHICLE_TYPE VT INNER JOIN VEHICLE_INVENTORY VI represents the joining of two tables. The INNER JOIN keyword combines records from both tables where the condition specified in the ON clause is true. This means that only the rows with matching values in the specified columns will be included in the result set.

In this case, the query is joining the 'VEHICLE_TYPE' table with the 'VEHICLE_INVENTORY' table on the column 'ModelCode'. It is used to determine the maximum and average MSRP (Manufacturer's Suggested Retail Price) for each distinct 'ModelName' from the two tables.

So, the correct answer is A. Assignment of a table alias, as the table aliases 'VT' and 'VI' are used to refer to the 'VEHICLE_TYPE' and 'VEHICLE_INVENTORY' tables respectively in the rest of the query.
