instruction:
In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as `a` for Yes or `b` for No.
question:
Question: Did Brett or Mayberry start playing professional baseball first? Passage:At Kauffman Stadium, Dennis Leonard pitched a four-hit complete game to give the Royals a 2–1 series lead. After a one-out walk and single, Freddie Patek's RBI single off of Mike Torrez in the second put the Royas up 1–0. Next inning, Al Cowens's groundout with runners on second and third and no outs made it 2–0 Royals. The Yankees got on the board in the fifth when Graig Nettles singled with two outs and scored on Lou Pinella's double, but the Royals got that run back in the bottom of the inning when Hal McRae hit a leadoff double, moved to third on a groundout, and scored on Cowens's groundout. Next inning, Torrez allowed a leadoff walk and single, then got two outs before being relieved by Sparky Lyle, who allowed a two-run double to Amos Otis. Next inning, George Brett hit a leadoff single and scored on John Mayberry's RBI double. The Yankees got a run in the ninth when Roy White doubled with one out and scored on first baseman Mayberry's error on Reggie Jackson's ground ball before Chris Chambliss grounded out to end the game.

question:
Question: Which opera that Brambilla performed at Teatro Carcano was written first? Passage:After her professional debut in 1831, Brambilla initially sang in several smaller opera houses in northern Italy but in 1833 scored a considerable success at Milan's Teatro Carcano singing Agnese in Bellini's Beatrice di Tenda and the leading soprano role in Fioravanti's Le cantatrici villane. She then appeared on Russia at the Odessa Opera House, which at the time specialised in Italian opera. Upon her return to Milan in 1837, she sang with her sister Marietta at La Scala in the world premiere of In morte di Maria Malibran de Bériot, a cantata in memory of Maria Malibran composed by Gaetano Donizetti, Giovanni Pacini, Saverio Mercadante, Nicola Vaccai and Pietro Antonio Coppola. After singing in Barcelona, she returned to La Scala for the 1839/1840 season in Mercadante's Le due illustri rivali and the world premieres of Mazzucato's I corsari and Coccia's Giovanna II.

question:
Question: When was the man whose name is used as the unit of radio wave frequency born?  Passage:A modulated radio wave, carrying an information signal, occupies a range of frequencies. See diagram. The information (modulation) in a radio signal is usually concentrated in narrow frequency bands called sidebands (SB) just above and below the carrier frequency. The width in hertz of the frequency range that the radio signal occupies, the highest frequency minus the lowest frequency, is called its bandwidth (BW). A given amount of bandwidth can carry the same amount of information (data rate in bits per second) regardless of where in the radio frequency spectrum it is located, so bandwidth is a measure of information-carrying capacity. The bandwidth required by a radio transmission depends on the data rate of the information (modulation signal) being sent, and the spectral efficiency of the modulation method used; how much data it can transmit in each kilohertz of bandwidth. Different types of information signals carried by radio have different data rates. For example, a television (video) signal has a greater data rate than an audio signal.
