Raj begins his speech asking the question, "Where is home?" He then continues by discussing how home used to mean his birthplace in Bangalore, but now it means an apartment in Chicago near Wrigley Field. Which principle of verbal messages does this demonstrate?

meanings are in people

Explanation:

The principle of verbal message that the text shown above express is "meanings are in people". That's because the meaning of what was a "home" was inside Raj, for that reason, he could call it home, different places that fit the meaning he kept inside him and not in the place itself. This allows him to feel at home in his homeland, but it does not interfere that he feels at home in his apartment in Chicago, because what makes a place become a home is within him.

often a noun phrase is just a noun or a pronoun:

people like to have money.

i am tired.

it is getting late.
