Two students had a contest to see who could build the fastest boat. Emily spent hours learning about boatbuilding and designing a boat that would be fast but stable in the water. Aaron spent his time painting his boat, making it look impressive and flashy, with red flames along the sides. At a contest, students gathered around to observe the two boats. They were impressed by the beauty of Aaron's boat. "Surely that one will be the winner," they said. But Aaron's boat tipped over and sank almost immediately, while Emily's boat chugged along to the finish line. Which statement best expresses a theme of this story?

B. It is more important to focus on the task at hand than to worry about appearances.
C. The more time one spends on a task, the better the quality of the outcome.
D. One should always take pride in looking one's best.
