Read the text Then choose the correct answer questions 51-52.Zach Bonner is "pretty tired", he says. Instead of going to camp this summer, Zach, aged 11, decided to walk 668 miles from Atlanta, Georgia, to the nation's capital, Washington, D.C. Why? Zach hopes to raise awareness about the life of homeless kids. His journey to help others began two years ago. Zach walked from his home in Tampa, Florida, to Tallahassee. Then, in 2008, he did it again, this time walking from Tallahassee to Atlanta. Since May, Zach has traveled 12 miles every day in his trusty Adidas shoes. Along the way he has collected more than 1,000 letters about homeless children. He hopes to give the letters to President Barack Obama. Zach says he wants his walk to make a difference. More than 1 million children in the United States live in shelters or on the streets. During his pilgrimage, Zach spent 24 hours with a group of homeless children. So he could learn the difficulties they face.
