Here's why:
* Subject-verb agreement: The subject "people" is plural, so the verb needs to be plural as well. "Tries" is singular.
* Incomplete thought: The sentence is missing a direct object or a prepositional phrase to complete the meaning.
Here are some possible corrections:
* People try to... (e.g., "People try to be kind.")
* People are trying to... (e.g., "People are trying to understand the situation.")
