Объяснение:

I, he, she, it - was (отрицательная форма: wasn't)

you, we, they - were (отрицательная форма: weren't)

в предложениях с there нужно посмотреть, какое существительное стоит после be (was\were). если оно множественного числа - то were (were there any interesting participants on it?), если единственного - то was (there was a new show on TV yesterday)

вопросительная конструкция: на первое место выходит be (was\were), потом подлежащее (просто меняем их местами) и дальше идет всё-всё-всё оставшееся от предложения

допустим, рассмотрим на примерах

1. it was from the moon
2. it wasn't from the moon
3. was it from the moon?
4. weren't it from the moon?

1. were there any interesting participants on it?
2. there weren't any interesting participants on it
3. there were interesting participants on it
4. weren't there any interesting participants on it?
