Read this excerpt from Dean Kamen's "On Becoming an Inventor." I had just finished making a complicated piece of equipment that was to be used for a show opening in Philadelphia called "Fiorello." When the machine arrived they had trouble wiring it, so instead of going off to college that morning for orientation, I spent several days at the theatre fixing my light/sound equipment. The show received poor reviews, except for the mention by one reviewer of the "special effects," which, he wrote, were "outstanding."

How do writing shape readers' impressions?

Kamen's opinion seems to be that machines are more important than anything else. He supports this with an example of his work on a machine for a show in Philadelphia. His tone is formal and directed at a scholarly audience.

Kamen’s opinion seems to be that hard work can overcome any obstacles. He supports this with an example of hard work on a light machine. His tone is humorous and directed at a young audience.

Kamen’s opinion seems to be that his inventions are more important to him than other activities. He supports this by sharing an example of skipping college orientation to fix sound equipment. His tone is informal and directed at a general audience.

Kamen's opinion seems to be that special effects can make a show outstanding. He supports this with an example of his own special effects machine. His tone is formal and directed at a scientific audience.
