    questions 71 to 75 are based on the following passage: 
    it was very late before guglielmo followed his brother up to bed, foran extraordinary idea had come to him. if a spark could cause ether wavesto travel to another machine across a room and make that machine spark,why couldn't a bigger spark make waves travel a longer distance and causeanother spark, say, a mile away? and, by using long and short sparks, whycouldn't this be used to send messages by morse code? indeed, why shouldn'tmessages be sent this way over great distances, using the ether instead ofwires? 
    the elder man found his young brother poor company during the rest ofthat holiday, for guglielmo was so interested in his idea that he couldnot take his thoughts off it. 
    at last they arrived home at their father's mansion outside bjologna,and young marconi hurried to his laboratory to start his experiments.assisted by his brother alfonso, who, although nine years his senior, was not ashamed to work under this brilliant young scientist, he struggled formonths testing his idea. at last, to their joy, they got the instrument atthe other end of the room to give its answering spark. 
    marconi now decided to show his father that there really was somethingin this idea of his, for signor marconi, who had made a large fortune inbusiness, had not a great deal of faith in his youngest son's science. 
    at last the apparatus was ready, and guglielmo invited his father andmother to come to the laboratory. 
    signor marconi entered, his good-humoured face beaming."what is thisnew toy you have made, my boy?"he asked. 
    "listen." the young inventor said, and he pressed a switch. 
    faintly, in the lower part of the big house, an electric bell rang. 
    "well?"his father inquired. 
    "there are no wires running to that bell. don't you see what it means.father? messages can be sent through space without wires to carry them." 
    but signor marconi was not convinced."let me take one of your machinesdown to the lawn. then, if you can send me a signal, i'll believe you."he said.
