This document summarizes two advertisements. For the BMW Z3: The ad depicts the car as a shark to imply it is fast, agile, and powerful like a shark. This suggests the car dominates over other cars. The target audience is likely younger people interested in sporty cars. For the Nike shoe: The ad shows many small people building the shoe to make it appear very large. This implies high quality from extensive time and effort. Nike may aim to position the shoe as their best product. The target is younger athletes aged 12-25 who will find the ad's humor and drama appealing.
