Explanation:
In this exercise, you have to complete the paragraph with the words ''para'' and ''por'' depending on the context of the sentences.
The uses are similar but, on one hand, you use ''por'' to talk about movement, in travel and communication and duration; on the other hand, you use ''para'' to talk about destinations, deadlines, and other situations.
