Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.

(A)

Margie Bland remembers the phone call from Iraq sometime before Christmas. Her son, Army specialist Joseph Darby , a military police officer in the reserves(not full – time soldiers), was on the phone and she could tell something was wrong.

Darby , 24 , would later come out as the soldier who first alerted the world to the abuse of Iraqi prisoners by US guards at Abu Ghraib prison in Baghdad on January 13. “I could tell in his voice he was not sleeping.” Blank , 45, recalls. “He said ‘I don’t fell good.’” Darby was feeling bad about something he thought was very wrong. “It was really hard on him”, his mother said. “He didn’t want to go against his troops, but he said he could not stand the cruelty he had discovered . He said he kept thinking , ‘What if that was my mum, my brother or my brother or my wife?’” Darby slipped an anonymous note under a military investigator’s door in January, about the mistreatment of prisoners. He later turned in a CD-ROM with 1,000 photos documenting the cruelty, according to a recently disclosed internal Army report. “I told him, ‘Your picture is in the paper, ’” Blank said. “I said, ‘Honey , you did a good thing and good always triumphs over evil ’ And he said, ‘You’re right, mum.’”

Darby grew up in western Pennsylvania, US To help his family, he worked at a fast food restaurant as a teenager and as a mechanic after graduating from high school. He thought the Army might lead to a better life—even a college education. So, like many others, he ended up in Iraq.
