How does this paragraph help develop the central idea?
In order to get a clean, sharp edge when applying a
second paint color, the first had to be masked, of course,
and this required that newspaper or butcher paper be
fastened to the car body. If shop-brewed glue was used, it
would sometimes stick so well that it had to be scraped
off, more often than not pulling paint with it. Surgical
adhesive tape was sometimes employed, but its cloth
backing tended to absorb solvents from the newly
sprayed paint and cause the masking materials to stick to
the paint they were intended to protect.
- The Evolution of Useful Things,
Henry Petroski
O It shows that shop-brewed glue did not stick well to the paint.
It shows that early attempts at finding the correct stickiness failed,
0 It shows that surgical adhesive tape was the ideal product to use.
O It shows that cloth backing was better than paper backing for glue.
