Answer:
The answer to the question: based on this image how does the viewer know that this ad contais bias, is, A: It was paid for by Reagan-Bush campaign funds.
Explanation:
This is what is stated in the ad itself, aside from naming Reagan as President and showing him enveloped by the American flag, as if it were his, as if the flag itself were claiming him as the only person suited for such an important role. The ad contains bias when it is paid by the campaign because by the funds being directly from the campaign, they are not limited to what they can show, and the message that they can send, and this is exactly what happens here. By showing Reagan enveloped in the flag, they send the unmistakable message that Reagan and Bush are the best choice in election.
