Today was the day, Heather decided. She would row that boat across the river in less than half an hour, beating her brother’s record. Of course, even on a sunny, windless day like today, she knew the task would be difficult. No matter the weather, the river currents were always strong. Still, Heather was strong, too. She was a very competitive person. She had been practicing rowing for months. She knew all the tips for using the oars to achieve speed and smoothness in the water. She had increased her upper-arm strength and mastered her rhythm and breathing. “I’ll show you,” Heather told her father. “A girl can be as good an athlete as a boy.” What can you conclude about Heather’s brother from evidence in the passage?
