The passage is suited for elderly people or people who aren't really familiar with tech. Is there any multiple choice answers?
This would definitely be FALSE. Being able to distinguish the subjects and objects will help you to avoid confusion on which verb or pronoun to use. We always follow the rules in subject-verb agreement as well as the pronoun-antecedent rules. Knowing either the subject is plural or singular will give you an idea on what verb to use. Same goes with the antecedents and pronouns to use.
In The Catcher in the Rye, we hear a lot from Holden Caulfield. This says something about his self-image or how he sees himself. Physically, he describes himself as having gray hair. Which means he thinks he looks old. He also thinks he is older mentally. Also, he feels like people neglect him which cause his struggles.
