Prepositions: nach or zu
In this exercise, you are required to choose the correct preposition (nach or zu) for each sentence.
Nach and zu, both mean "to." However, nach is used with reference to geographic locations or directions; zu is used in all other cases except these. Also, zu is always used with an article or combined and contracted with the article that follows it. For e.g. zu dem Postamt becomes zum Postamt.
