Step-by-step explanation:
The reading talks about a past trip to a department store, so most of the verbs would be conjugated in simple preterit. However, the first one should be in simple present because even if all the other actions happened in the past, the store presently remains at the same distance from the hotel. Almost all the other conjugations are straightforward, except for number 7 and 10. In 7 the noun is "todo el mundo" which refers to a group of people, but is singular noun as it refers to a group, which is why it's conjugated in third person singular. In number 10 the verb "ser" is irregular, so it has particular forms to conjugate and the third person plural is "fueron".
