SELECT Name FROM country WHERE GovernmentForm = 'Constitutional Monarchy' AND Continent IN ( 'Europe', 'Oceania' );

Answer 1

The correct SQL queries to list countries with constitutional monarchies in Europe and Oceania are the ones using the 'OR' or 'IN' operator within the WHERE clause. The third option using 'IN' is the most efficient and readable, but the first and third options are correct.

Step-by-step explanation:

To list the countries with constitutional monarchies in the continents of Europe and Oceania, we need to create an SQL query that includes the appropriate filtering conditions within the WHERE clause. Since a country cannot be on two continents at the same time, the use of 'AND' in the second query option is incorrect. The correct SQL queries would be the ones that use the 'OR' or the 'IN' operator to encapsulate multiple continent options:

• SELECT Name FROM country WHERE ( GovernmentForm = 'Constitutional Monarchy' AND Continent = 'Europe' ) OR Continent = 'Oceania';
• SELECT Name FROM country WHERE GovernmentForm = 'Constitutional Monarchy' AND ( Continent = 'Europe' OR Continent = 'Oceania' );
• SELECT Name FROM country WHERE GovernmentForm = 'Constitutional Monarchy' AND Continent IN ( 'Europe', 'Oceania' );

The third query option is the most efficient and readable method, as it specifies the search for constitutional monarchies within the listed continents using the 'IN' clause. However, as the answer requires the selection of two choices, both the first and third queries would return the desired results.
