Explanation:

1.

The sentence says they had to use torches, so a power cut (loss of electricity) makes sense.

They'll collect it tomorrow, and "rubbish" is something collected, so this fits.

Cars and lorries cause pollution, and the mention of electric buses relates to reducing pollution, so pollution is correct.

Answer:

power cut
