'He wore round glasses held together with a lot of
Sellotape because of all the times Dudley had punched
him on the nose. The only thing Harry liked about his
own appearance was a very thin scar on his forehead
which was shaped like a bolt of lightning.' (Harry Potter
and the Philosopher's Stone, by J.K. Rowling)
Based on this excerpt, which adjective could be used to
describe Harry's glasses and scar in the comparative and
superlative forms, respectively?
