Explanation:

Ronald Reagan's address on the space shuttle Challenger appeals to emotions.

Looking at the address, we discover that he sympathizes with the families of the astronauts that lost their loved ones.  He stated "For the families of the seven, we cannot bear, as you do, the full impact of this tragedy. But we feel the loss, and we're thinking about you so very much". Those lines in the address actually invoke feelings of pity and sympathy in the audience.
