Solution:

SELECT NAME FROM CITY WHERE POPULATION > 120000 AND COUNTRYCODE = 'USA';

Explanation:

• SELECT NAME: This part of the query specifies that you want to retrieve the NAME field.
• FROM CITY: Indicates that you are selecting data from the CITY table.
• WHERE POPULATION > 120000: This condition filters the rows and includes only those cities where the population is larger than 120,000.
• AND COUNTRYCODE = 'USA': This additional condition ensures that only American cities (USA) are included in the result, based on the CountryCode column.
