According to the narrator Halloween is a...
patchwork holiday.
mainly religious holiday.
only cultural holiday.

Samhain celebrated...
the spread of the Celts culture across Europe.
the death of the living.
the end of the harvest season.

The Catholic church frowned on the pagan rituals, which means that...
it accepted them.
it didn't approve of them.
it ignored them.

Halloween was brought to America...
by Irish immigrants escaping from poverty.
by Irish immigrants looking for the potato famine.
by Irish immigrants who wanted to conquer America.

Over the years the harmless tricks...
became more popular.
turned into something different.

So the neighbours started to give ... to stop the tricks.
