How old were the bones thought to be?

Why were the bones sent to the USA?

What happened to the woman after she made contact with the Chicago businessman?

What happened a few years later?

We can infer from the passage that .

Questions 1 to 5 are based on the folloxving passage :In the 1920s, scientists found a collection of bones near Beijing, China.They believed that the bones were human and that they were about 500,000 years old.They also believed the bones were important because they were from a little-known stage in the evolution of human beings.The bones were kept in Beijing until 1941.Then, because the Japanese army was advancing towards the city, the scientists decided to send the bones to the United States for safety. Since then Nobody heard anything about them at all.Dr Harry L. Shapiro, Professor of Anthropology at Columbia University, has been searching for them ever since. He believes that they were stolen by the American army whose job was to take them to the USA.He could be right. After the war, a Chicago businessman offered $5,000 to anybody with information about the bones. A woman phoned him and told him she knew where the bones were.He arranged to meet her on the 102nd floor of the Empire State Building in New York. They met and she told him that her husband had come home from China with fossils of a prehistoric man. She showed him a photograph of them. Then she walked away and was never heard from again.A few years later, however, a Sydney businessman reported that he had the bones and that he had buried them in a forest in Tasmania. He offered to say where for a large sum of money. Then he, too, was never heard from again.Someone, somewhere, has these bones, but nobody seems to know who or where.
