WHERE promo_begin_date IN (SELECT promo_begin_date
FROM promotions
WHERE promo_category= 'INTERNET');
SELECT promo_name, promo_begin_date FROM promotions

C.WHERE promo_begin_date> ALL (SELECT MAX (promo_begin_date)
FROM promotions) AND
promo_category= 'INTERNET';

D.WHERE promo_begin_date> ANY (SELECT promo_begin_date
FROM promotions
WHERE promo_category= 'INTERNET');
