• Forest rangers say that we can prevent forest fires.

• Here 'say' has been used due to plural number 'rangers'. Rangers are third person plural number, that's why instead of says 'say' is correct for the blank space. Because it is written in Simple Present Tense.

• The complete sentence is an example of Noun Clause ( Object of Transitive Verb ).

Answer 2

Forest rangers _____ (says/say)  that we can prevent forest fires​

Answer:

Forest rangers say that we can prevent forest fires​.

• In the above sentence, we use ''say'' as it satisfies the subject-verb agreement.

• In ''subject-verb'' agreement, subjects and verbs must agree with one another.

• If the subject is singular then the helping verb is also singular whereas if the subject is plural then the helping verb is also plural.

• If the noun is singular then add ''s'' to the verb. If the noun is plural then no need to add ''s'' to the verb.

• In the given sentence, the noun ''Forest Rangers'' is plural so no need to add ''s'' to the verb.
