Practice 1  Directions: Read the texts from the “LETTERS” section of a magazine in which five people commented on the magazine’s story of Bono, a superstar. For questions 1 to 5, match the name of each person (1 to 5) to one of the statements (A to G) given below. Mark your answers on ANSWER SHEET 1.  Caroline Hartman:  Thanks for the terrific article on U2’s Bono and his efforts to save Africa from financial ruin. He’s not a saint. He is a hard-working, real man, using his gifts to inspire us in song and make a difference in the world. Some issues are so serious that most of us don’t even try to fix them. Bono can’t save the world by himself, but like others who have shown the way, such as Martin Luther King, Jr. and Mohandas Gandhi, he is proving that one man can make a difference.  Molly Leusehel:  Bono may be smarter, better informed and more committed than other stars, but Africa’s problems are larger than his ambition. After living in Africa nearly six years, I returned to the U.S. with more questions than answers. Debt relief is a noble idea, hut most foreign aid does little to enrich the life of the average African.  Amanda Adiehie:  I am a 24-year-old Nigerian and have often viewed stars’ “concern”for Africa with resentment. My reaction to Bono was different: I was impressed. He is right in recommending not only debt relief but the lowering of trade restrictions on African countries. What Africa needs is not gifts of fish but fair access to the fishing pond.  Mallni Ranganathan:  Your story on the smartest superstar on the planet was brilliant. I felt like I was right there with him, there to nod my head in approval and to believe in the potential of his African-debt-relief campaign, there to appreciate the peculiar, stubborn, witty and human sides to a guy who seems too famous to be real. Hats off to you for capturing these features so aptly and for making Bono’s personality so real, his cause so true.  Lynne Pereira:  I loved your article on Bono, but why the annoying wording on your cover: “Don’t laugh--the planet’s biggest rock star is on a mission to make a difference”? Who would want to laugh? Bono has proved that he’s willing and able to do what plenty of world leaders can’t or won’t do put his money where his mouth is and make a difference.  Now match each of the people (1 to 5) to the appropriate statement.  Note: there are two extra statements.  Statements
