SUMMARIZING 1 27 , Report the content accurately You will be evaluated not only on how wen you use language to write a summary but also on how accurately you understand and report the content 01 the original, Read and listen for meaning, When you have finished reading or listening, review the content. Ask yoursetf some basic questions. Include the questions that reporters use in their writing- who, what, when, where, why , how? The content may not include answers to an 01 the ques- tions, but, with practice, you win be able to identify the questions that are important to the content you have read or heard. f'RAcna Acmm 27 Did you unclerstand? Answer the content questions. Then, copy !tie answers to the questions in paragraph lorm to make a summary. The answers and the example summaries are printed in Chapt er 7 on pages 525-526. 1. /ludl", According to the controversial sunspot theory, great storms on the surlace 01 the Sun hurt streams 01 solar particles into space and eventually into the atmosphere of our planet, causing shifts in the weather on the Earth and interlerence with radio and television communications. A typical sunspot consists 01 a dark central umbra, a WOI'd dertved from the Latin word lor shadow , which is surrounded by a lighter penumbra of light and dark threads extending out Irom the center like the spokes 01 a wheel. Actually, the sunspots are oooIer !tIan the rest of the photosphere, which may account lor their apparently darker color. Typically, the temperature in a sunspot umbra is about 4000 K, whereas the temperature in a penumbra registers 5500 K, and the granules outside the spot are 6000 K. Sunspots range in size from tiny grains to complex structures with areas stretChing for bil- lions of square miles. About 5 percent of all sunspots are large enough so that they can be seen from Earth without instruments; consequently, observations of sunspots have been recorded for thousands 01 years. They have been observed in arrangements of one to more than one hundred spots, but they tend to occtJr In pairs. There is also a marked tendency lor the two spots of a pair to have opposite magnetic polarities. Furthermore, !tie strength 01 the magnetic field associated with any given sunspot is closely related to the spot's Size. Sunspots have also been observed to occtJf in cycles, over a period 01 eleven years. At the beginning of a cycle, the storms occur between 20 and 40 degrees north and south of the equator on the Sun. As the cycle continues, some of the storms move closer to the equator. As the cycle diminishes, the number of sunspots decreases to a minimum, and they cluster between 5 and 15 degrees noflh and south latitude. Although !tIere is no theory that completely explains the nature and lunction 01 sunspots, several models show scientists' a"empts to relate !tie phenomenon to magnetic lield lines aloog the Moos olloogitude lrom tile north and sou!tl poles 01 the Sun.

Since 1913, the Federal Reserve System has served as the central bank lor the Urited States. The Fed's primary function is to control monetary policy by influencing the cost and availability 01 money and credit through the purchase and saie 01 government securities. II the Federal Reserve pr0- vides too little money, interest rates tend to be high, borrowing is expeosive, business activity slows down, unemployment goes up , and the danger 01 a recession is augmented. On the other hand, if there is too mlJC h money, interest rates decline, and borrowing can lead to excess demand, pushing up prices and lueling inflation. In addition to oontrolling the money supply, the Fad has S&Vef8 i other responsibilities. In collaboration with the U.S. Department of the Treasury. the Fed puts new coins and paper currency into circulation by issuing them to banks. It also supervises the activities 01 member banks abroad and regulates certain aspects 01 international finance. The Federal Reserve System consists of twefve district reserve banks and their branch offi ces along with several comm ittees and councils . All national commerc ial bank s are required by law to be members 01 the Fed, and aN deposit-taking institutions like credit unions are subject to regulation by the F ed regarding the amount of deposited funds that must be hek:l in resefVe and that, by definition, therefore, are not available lor loans . The most powerful body is the seven-membef board of governors In Washington, appointed by the President and confirmed by the Senate. Although it Is tNe that the Federal Reserve does not depend on Congress lor budget allocations, and !herefofe is free from !he partisan politics that inlluence most of the other governmental bodies, it is still responsible lor frequent reports to the C0n- gress on the conduct of monetary policies. In many ways, the Federal Reserve is like a foorth branch of the Un ited States government because it Is composed of national policy makers. However, in practice, the F ed does not stray lrom the linancial policies established by the executive branch 01 the government.

""'" Charles Ives, who is now acclaimed as the first greal AmerICan composer o llne twentietn century, had to wail many years l or the public recognition he deserved. 80m 10 music as the son of a bandmaster, Ives played drums in his lather's community band and organ at the local church. He entered Yale University al twenty \0 study musical oomposition with H or atio Pan<er, but alter graQuation he chose nolto pursue a ca reer in musiC. He suspected correctly Ihat the public would not accept the music he wrote because Ives did not follow the musical fashion of his times. 'Nhile his contemporaries wrote lyrical songs. Ives transfigured music and musical form. He quoted, combined, insinuated, and distorted familiar hymns, marches, and battle songs, while e)(perimenting with the effects of polytonality. or the Simu ltaneous use of keys with conflicting rhythms and time, Even when he could convince some musicians to show some interest in his compositions. after assessing them conductors and performers said that they were essentlaJly unplayable. !vas turned his altention to business. He became a successful insurance e)(ecutive, build- ing his company i nlO the largest agency in the country in only two decades. Although he occa- sionally hired musicians to play one of his won<s privately lor him, he usuaJly heard his music only in his imagination. After he reoovered from a serious heart altack, he became reconciled to the fact that his ideas, especially the use of dissonance and special effects, were just tOO dif- ferent for the musical mainstream to accept. Determined to sh are his music with the few pe0- ple who mig ht appreciate it, he published his won< privately and distributed il free. In 1939 , when Ives was si)(ty-five, American pianist JOh n Kirkpatr iC k played Concord Sana/a in Town Hall. The reviews were laudatory, One review er proclaimed it "the 9reatest music composed by an American By 1947, Ives was famous. His Second Symphony was presented to the public In a perlonnance by the New Yorl< Philharmonic. fifty years alter it had been wrilten. The same year, Ives received the Pulitzer Prize. He was seventy-three. S r ", Charles Ives started his musical career as a member of his father'S band and received a degree from Yale University in music, but he became a businessman instead because he was alraid that his music would not be well accepted, His music was very different fr om Ihe popu- SUMMARIZING 133 lar songS of his era because he used small phrases from well-known music with unusual rhythms and tones. Fifty years after he wrote his Second Symphony , it was performed by the New YorI!. Philharmonic, and he as a arded the Pulitzer Prize.
