听力原文： A newspaper reports Saudi Arabia’s Crown Prince Abdullah has canceled a visit to Canada over criticism for the alleged mistreatment of a Canadian citizen detained in a Saudi prison.
Saudi Arabia’s A1-Riyadb newspaper quotes Saudi officials as saying the trip has been called off because of what they call "unacceptable interference" by Canadian officials and some of Canada's newspapers.
The dispute is over 43-year-old William Sampson, who is being held in Saudi Arabia in connection with two bomb explosions in November. The blasts killed a British citizen and injured several other people in the capital, Riyadh. Mr. Sampson could face the death penalty if found guilty of murder.
Canada’s National Post newspaper recently quoted a close friend of the prisoner as saying Mr. Sampson had been taken to a hospital on May 17 with a crushed vertebra, foot injuries and scratched wrists. Saudi officials have said the injuries were the result of a suicide attempt.
The Canadian government rejected the torture allegations after receiving a report from its ambassador who visited Mr. Sampson with a European doctor in a hospital on Monday.
What crime is William Sampson charged with？
A．Bombing.
B．Arson.
C．Rape.
D．Burglary.
