Many countries in europe have a continental climate what is the best way to explain the effects of climate has on these countries

A continental climate is a climate that is distinguished by seasons: hot summer and cold winters. Without knowing the options, I would say that the biggest influence it has on the countries is by structuring life in those countries according to the seasons.

So, for example school is closed in the summer because historically, children were helping their parents at harvest!

This would be an open primary. a closed primary people can vote only prior to election day if the party if they are registered. independent voters can not participate. there is not a wide-open primary, but there is a semi-open primary.
