Input: Consider Input: Article: Born with easy-broken bone disease, Zhang Yonghong is only half a meter tall and must use a wheelchair. His thin arms and legs can hardly support any weight, and he is unable to take care of himself. However, his hands are able to produce fine paper-cuts, which will free his daughter from the same disease. To support himself, he learned how to make paper-cut art from his mother. He sold his artwork and taught his techniques in Xi'an for eight years before discovering his young daughter _ the disease from him, leading Zhang to move his family to Beijing for his daughter's better treatment five years ago. The daughter's treatment costs about 30,000 yuan a year. The family's savings was used up in two years, and Zhang was forced to start to sell his work in underground passages with his healthy wife, who soon left him because of the hard life. With a little help from government, he was lucky to meet some kindhearted people in Beijing. A Hong Kong businessman gave 60,000 yuan to him last year to treat the girl and start a small shop on Qiangulouyuan, which is known as a famous hutong that attracts lots of tourists over holidays. Zhang Rui, a university graduate, spends most of her time helping Zhang sell the paper-cuts, translating the stories of the paper-cuts into English and selling the works on the roadside of Nanluoguxiang. However, the artist still lives beyond his income and struggles to continue his small business. "Selling paper-cuts is his only source of income. Without this, he can't support the family and treat his daughter," says Zhang Rui, who hopes more people will help Zhang.
Answer: His easy-broken bone disease affected him.

Output: Why did Zhang grow only half a meter tall?

Input: Consider Input: Article: Many years before the United States was founded, Americans had already invented barbecues. But the first barbecues, in fact ,were the invention of the Taino Indians of Haiti, who dried their meat on raised frames of sticks over fires. Spanish explorers spelled the Taino word as barbacoa, and as time passed, English settlers along the Atlantic coat had their own barbecues. One summer day in 1773, Benjamin Lynde, a citizen of Massachusetts, wrote in his diary, "Fair and hot ; Browne; hack overset." That is , on a bright and hot day he went to the Brownes to attend a barbecue, and his carriage fell over. It shows that the barbecue had its social occasion by that time. Large animals would be roasted whole on frames over hot fires, and neighbours would be invited to dinner. In later centuries, as settlers moved to the west, the barbecue went along with it, reaching an especially large size in Texas, where a pit for fuels such as tree branches might be over ten feet deep. Today, the barbecue grills which are fueled by charcoal or electricity are likely to be small and easy to move , and can cook only parts of an animal at a time, but people still have barbecues out of doors and always invite their neighbours or friends over.
Answer: Taino Indians.
Output: Who invented the barbecues first in history?
