Answer:
This is the best one of the articles about Pocahontas that I found.
Explanation:
Demonstrative pronouns are those pronouns that are used to point out to something that is specific in the sentence, or represent the thing or things in the sentence. Like the name suggests, they demonstrate the thing that is mentioned or talked about in the sentence. So, from the above provided sentence,
"This is the best one of the articles about Pocahontas that I found"
"THIS" is what demonstrates what the sentence is talking about and indicates or points out the main thing that the sentence is about.
