Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_15597 ( "1910s" real, "1920s" real, "1930s" real, "1940s" real, "1950s" real, "1960s" real, "1970s" real, "1980s" real, "1990s" real, "2000s" real )

### Question ###
What is the range for the 1980s that correspond to a grid 1910s of 1912, and a 1940s before 1942

### Accurate SQL ###

SELECT AVG("1980s") FROM table_15597 WHERE "1910s" = '1912' AND "1940s" < '1942'
