Final answer:
In this conversation, the words 'endorsed', 'implied', 'promoted', 'proved' are used to discuss the ways in which a laundry detergent is being promoted and how the claims made about it are not supported by evidence.
Step-by-step explanation:
Salim: I thought it would be a lot better than our regular brand. It was endorsed by a bunch of famous athletes.
Alani: Do you really believe they all use this stuff?
Salim: Well . . . they implied that they did. They stood there holding the detergent and talked about how clean their clothes were.
Alani: Where did you see this?
Salim: In commercials. They were on TV during all the football games.
Alani: So it's being promoted to sports fans. Have you seen any evidence that it works?
Salim: No.
Alani: Well, I tried it out, and unfortunately I proved that it's not very good at cleaning clothes. Just look at your pants.
Salim: Oh, no! I thought that grass stain would come out.
Alani: I thought so, too. The coffee I spilled on my blouse didn't come out, either.
Salim: I'll wash them again tonight with our regular brand . . . and next time I won't believe everything I see on TV!
