CREATE TABLE table_10301 ("Year" FLOAT, "Tournament" CLOB, "Venue" CLOB, "Result" CLOB, "Extra" CLOB)

what is the result when extra is 4 x 100 m relay and the year is later than 1971?
SELECT "Result" FROM table_10301 WHERE "Extra" = '4 x 100 m relay' AND "Year" > '1971'
SELECT "Result" FROM "table_10301" WHERE "Extra" = '4 x 100 m relay' AND "Year" > '1971'
