Question

1．Cyril was a small town．The houses there were all made of wood； almost everything in the houses were made of wood，too．And all the houses faced south．The town was never peaceful．Fire broke out once a week on summer afternoons．People were puzzled who was the real firebug （纵火犯）．
One day a big fire broke out．It was said that a Negro（黑人） had jumped out of the house on fire，so the police arrested all the Negroes in the street．However，there were fires breaking out when the Negroes were in prison．
Mauson，a physics teacher，didn't believe that the Negroes were the firebugs，and decided to find out who the real firebug was．One day，he was invited to drink in a pub and happened to notice that many bottles and plastic plates were baked by the hot sunrays．Suddenly he realized what the actual fact was．He dashed out of the pub to his friend's house nearby，which also faced south．He made an experiment there to prove his idea．
The next Saturday afternoon，Mauson asked some policemen to come to the house．They were told that the real firebug would be shown there．At that time，the sun was shining full into the house and it became hotter and hotter inside the room．"Now，"said Mauson，"this house will soon catch fire．"People looked at each other in surprise．Mauson asked them to look at the bottles and focus on the table cloth．After a while the cloth gave off a burning smell and began to catch fire!
The mystery of fire was discovered，but the police wouldn't believe him and insisted that Negroes had been the firebugs．Instead they arrested Mauson and put him into prison．But Mauson said he would never turn against science．
