List circuits which host 4 f1 races from year 1990 to 2000.
from year 1990 to 2000 refers to year(date) between 1990 and 2000;
SELECT DISTINCT T1.name FROM circuits AS T1 INNER JOIN races AS T2 ON T2.circuitID = T1.circuitId WHERE STRFTIME('%Y', T2.date) BETWEEN '1990' AND '2000' GROUP BY T1.name HAVING COUNT(T2.raceId) = 4
