теперь объяснения.
В первом мы выбрали вариант а, т.к. Земля вращалась, вращается, и будет вращаться вокруг Земли.
Во втором вариант с, т.к. мы знаем точное время, поэтому это не present perfect и не present simple, следовательно остается лишь один вариант.
В третьем действует правило, что, если вначале стоит без отрицания глагол, то в "хвостике" мы вставляем с отрицанием и наоборот + местоимение какое там было.
Удачи в учебе!
