Answer all questions about the information in a passage on the basis of what is stated or implied in that passage.
The Richter scale is a numerical logarithmic scale developed and introduced by American seismologist Charles R. Richter in 1935. The purpose of the scale is to measure the amplitude of the largest trace recorded by a standard seismograph one hundred kilometers from the epicenter of an earthquake. Tables have been formulated to demonstrate the magnitude of any earthquake from any seismograph. For example, for a one-unit increase in magnitude, there is an increase of times thirty in released energy. To put that another way, each number on the Richter scale represents an earthquake ten times as strong as one of the next lower magnitude. Specifically, an earthquake of magnitude 6 is ten times as strong as an earthquake of magnitude 5. The Richter scale considers earthquakes of 6.75 as great and 7.0 to 7.75 as major. An earthquake that reads 4 to 5.5 would be expected to cause localized damage, and those of magnitude 2 may be felt. It is estimated that almost one million earthquakes occur each year, but most of them are so minor that they pass undetected. In fact, more than one thousand earthquakes of a magnitude of 2 or less occur every day.

Charles Ives, now acclaimed as the first great American composer of the twentieth century, had to wait many years for the recognition he deserved. The son of a bandmaster, Ives entered Yale at twenty to study composition with Horatio Parker, but after graduation, he did not choose to pursue a career in music. He suspected correctly that the public would not accept the music he wrote. Even the few conductors and performers he tried to interest in his compositions felt that they were unplayable. Instead, he became a successful insurance executive, building his company into the largest agency in the country in only two decades. Even during that busy time, he still dedicated himself to composing music in the evenings, on weekends, and during vacations. Although he occasionally hired musicians to play one of his works privately for him, he usually heard his music only in his imagination. After he recovered from a serious heart attack, he became reconciled to the fact that his ideas, especially the use of dissonance and special effects, were just too different for the musical mainstream. Determined to share his music with the few people who might appreciate it, he published his work privately and distributed it free. In 1939, when Ives was sixty-five, American pianist John Kirkpatrick played Concord Sonata in Town Hall. The reviews were laudatory. One reviewer proclaimed it “the greatest music composed by an American.” By 1947, Ives was famous. His Second Symphony was presented to the public in a performance by the New York Philharmonic, fifty years after it had been written. The same year, Ives received the Pulitzer prize. He was seventy-three.
