Answer:
The evidence of Timothy's stubbornness is he does the opposite of what Phillip says.
Step-by-step explanation:
The Cay is a written by Theodore Taylor for teenage children. The novel was contemplated on the real-life incident of 1942, when a 11-year-old boy was drifted away on a liferaft after Hato was torpedoed.
In the book, Phillip, calls Timothy stubborn again and again. At the end of chapter 6, Phillip again identifies Timothy as a stubborn man. The evidence that Phillip gives is that Timothy does exactly opposite of what Phillip asks him to do.
In this particular incident, Phillip insist upon not going to the island but Timothy impose that they will go to the island.
