Explanation:

In this exercise, you must write the form of the verb that corresponds to the subject that the sentence is refering to.

In the first sentence, the subject is "los países", which is "ellos" (they), so the verb "conservar" is conjugated for the third person plural.

In the second sentence, the subject is "el sendero", which is a singular third person, and it is "taking us" to the volcano's crater. In this case, the suffix of the verb "llevarnos" is placed separately before the verb to indicate the action that the path is taking with us.

In the third sentence, we are talking about a singular third person as well, but in this case, the population just wants to change the laws, so the verb stays in the simple conjugated form for the singular third person.

In the fourth sentence, the logic is the same as the first one. In this case, the people are a third person plural as well, so the verb "reducir" is conjugated as "reducen".

In the fifth sentence, we are talking about us, and we are a first person plural. In these cases, we usually add the suffix -mos to the verbs, so in this case we have "sabemos".

answer:   i cant   remeber exactly but i just got out of spanish a few months ago and the dbas are really easy. just relax, and have your notes in front of you. they are going to ask you the basics study the notes you wrote and you will be fine, make sure to really study grammar and pronuciation. the spanish teachers are usually nice so if you mess up they will go easy on you. you got this, you did the lessons and tests just focus and dont overthink the process.
