CREATE TABLE table_41783 ("Date" CLOB, "Score" CLOB, "Set 1" CLOB, "Set 2" CLOB, "Set 3" CLOB, "Set 4" CLOB, "Set 5" CLOB, "Total" CLOB)

What is Set 4, when Set 5 is NA, and when Set 3 is 19-25?
SELECT "Set 4" FROM table_41783 WHERE "Set 5" = 'na' AND "Set 3" = '19-25'
SELECT "Set 4" FROM "table_41783" WHERE "Set 3" = '19-25' AND "Set 5" = 'na'
