最近，通勤客机坠落事故的急剧增加在很大程度上是由于飞行员缺乏经验所致，作为一个主要增长的工业部门，通勤客机最近对有经验的飞机驾驶员的需求量剧增。然而，对飞机驾驶员的经验进行确定和评估是不可能的。例如，一个在气候良好的亚利桑那州飞行1000小时的教官，是不能和一个在充满暴风雨的东北部飞行1000小时的夜班货机飞行员相比的。

作者关于通勤客机坠毁事故的增加是由于飞行员缺乏经验所致的结论，最能被作者的哪一项疏忽所削弱？（）

A．认为不可能衡量飞行员的经验

B．使用了一个与所阐明观点在逻辑上不相关的例子

C．对往返航空公司飞机坠毁事件的增加只给出了片面的解释

D．对飞行教官的经验与夜班货机的经验作了一个不公平的比较

Last year, Sean Martinovich, from Whitianga, had life-saving surgery when a golf-sized tumor was removed from his brain stem. But the operation left half his face paralysed. He talked with a slur, sometimes dribbled out of the side of his mouth and could. not close his eye properly. Although he could run around with the other boys in the playground, when they laughed he could not laugh with them. Without a smile, he would suffer psychologically and emotionally.
Last week, 6-year-old Sean had seven hours of microsurgery that should give him back his smile. Doctor Bartlett removed a nerve from the back of one of Sean’s legs and transplanted it into his face, On the normal side of his face the nerve divides into lots of little branches. "We’ll cut those nerve branches and then we’ll take a nerve graft from one leg and tunnel it across his face from one side to the other end join that on to the nerve that’s been cut on the good side of his face," Doctor Bartlett said, before the operation. "If this was not fixed, he could face physical and emotional problems as he got older," Doctor Bartlett said. "Socially, people can become quite withdrawn because of face paralysis. It’s easy for people, especially children, to become rather emotionless because they prefer the flatness of no movement on either side to the weirdness of an asymmetry of smiling off one side and having this twisted face."
Sean is not smiling yet. Over the next six months the nerves will grow across the face to the damaged side and after that movement will hopefully come back. Sean’s parents, Steve and Wendy Martinovich, said they had been through a year of hell. But their son was a determined boy who just got on with it, said Mrs. Marfinovich. They are amazed at the technology that they hope will restore the cheeky smile they love so much. For Doctor Bartlett the microsurgery is almost routine. For Sean’s parents, it is a miracle.

According to Doctor Bartlett, If the nerve was not fixed, Sean Martinovich could face physical and emotional problems as he got older. Why

A．Because he may not want others to see the weirdness of an asymmetry when smiling, so he will choose to withdraw.

B．Because other children will be scared to see his face.

C．Because he will go through a year of hell.

D．Because other children will refuse to talk or play with him.
