Все так, предложения корректны:
Many questions were answered by the president at his annual conference last Thuesday.
Переводить на русский лучше в активе: "Президент ответил на многие вопросы во время ежегодной конференции на неделе во вторник".
Но форма глагола в пассиве: were answered by the president (были отвечены президентом)
У каждого времени и формы глагола есть свои маркеры. Если last Thuesday - значит Past Simple, если were answered by - значит Passive Voice. Если переводить дословно, то получится: "Много вопросов было отвечено президентом на ежегодной конференции в вторник", просто звучит некрасиво, потому переводить на русский лучше в активе.
The candeles were lighting on the birthday cake when Sam returened from work.
В переводе: "Свечи горели на именинном пироге, когда Сэм пришел с работы".
Предложение целиком относится к описывает одно короткое действие (Past Simple) во время продолжительного (Past Continuous) - все верно.
Every year patriotic songs are heard everywhere in the USA on July 4.
В переводе: "Каждый год патриотические песни слышны в каждом уголке Соединенных Штатов 4 июля".
Если Every year on July 4 - значит постоянное действие, берем Present Simple, если они слышны, а не сами слушают - значит Passive Voice.
