READING COMPREHENSION
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 ed 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 ? 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.
Marconi took him at his word. A little later he was back in the lab, hishand on the morse key. Through the window he could see his father at thereceiver. The young man's heart thumped as he tapped ?- the test signal, S,which telegraphists use. He could tell
by the expression on his father'sface that the message had got through.
That evening Signora Marconi talked to her husband and on the followingday Guglielmo was overjoyed to receive from his father 5,000 lire -- about??250 -- to help with his experiments.

Questions 76 to 80 are based on the following passage:
Yellow fever is a disease of warm lands that is found mainly along theshore of the Atlantic Ocean. It was first noticed in the Americas, but maywell have come form Africa and reached the New World with or soon afterColumbus. Until about fifty years ago, yellow fever was still one of themost feared diseases in the United States, where many died in repeated out-breaks. An outbreak which was to lead to surprising developments was onethat happened in Cuba during the Spanish-American War.
As a result, an army group under Major Walter Reed was sent there inJune, 1900 with orders "to give special attention to questions concerningthe cause and prevention of yellow fever". In a daring group of experimentsusing human beings, Major Reed proved the truth of an idea advanced in 1881by a Cuban doctor, that the city type of mosquito passed on the disease.
The successful result of these experiments gave birth to another andstill more important idea: kill off the city type of mosquitoes and therewill be no more yellow fever. Fortunately these mosquitoes are one of theeasiest types to destroy. They are born in pools of quiet, warm water,within a short distance to people's home.
So to Havana came a General with orders from the United States Govern-ment to dry up these pools. He carried out his task so well that the mos-quitoes disappeared. With them went yellow fever, never to return to Havana.A few years later the same General success
fully repeated this operation inPanama and in this way made possible the building of the Panama Canal. Itall seemed so simple. End the mosquitoes: end the disease. Man even beganto dream of getting rid of yellow fever from the world.
Meanwhile one question still remained unanswered. The city type of mosquitoes carried the fever, without doubt, but how? After many experi-ments, a member of the United States Army Yellow Fever Commission decidedthat the disease must be carried by something too small to be seen. Ofhis own free will, this devoted scientist decided to allow himself to bebitten by an infected mosquito. Then, taking some of his infected blood,he injected it into three other members of the group who wanted to of the three got yellow fever -- and recovered. This showed that thedisease was carried by a virus (2???) too small to be seen through the
microscopes of the day.
76. Yellow fever is found mainly around _______.
A) the Atlantic Ocean B) Any warm ocean
C) the Americas D) Any warm country

Questions 81 to 85 are based on the following passage:
It's never easy to admit you are in the wrong. Being human, we allneed to know the art of apologizing. Look back with honesty and think howoften you've judged roughly, said unkind things, pushed yourself ahead atthe expense of a friend. Then count the occasions when you indicatedclearly and truly that you were sorry. A bit frightening, isn't it? Frightening because some deep wisdom in us knows that when even a smallwrong has been committed, some mysterious moral feeling is disturbed; andit stays out of balance until fault is acknowledged and regret expressed.
I remember a doctor friend, the late Clarence Lieb, telling me abouta man who came to him with a variety of signs: headaches, insomnia andstomach trouble. No physical cause could be found. Finally Dr. Lieb saidto the man, "Unless you tell me what's worrying you, I can't help you."
After some hesitation, the man confessed that, as executor of hisfather's will (ò???), he had been cheating his brother, who lived abroad,of his inheritance. Then and there the wise old doctor made the man wri
teto his brother asking forgiveness and enclosing a cheque as the firststep in restoring their good relation. He then went with him to the mailbox in the corridor. As the letter disappeared, the man burst into tears."Thank you,"he said,"I think I'm cured."And he was.
A heartfelt apology can not only heal a damaged relationship but alsomake it stronger. If you can think of someone who deserves an apology fromyou, someone you have wronged, or judged too roughly, or just neglected,do some-thing about it right now.

Questions 86 to 90 are based on the following passage:
In 1791 the French nation, in the midst of a revolution, wished to breakwith the past, especially with those aspects of it which they consideredillogical and useless. One of those was the traditional system of weightsand measures in use. Not only was the system overtly complicated, but italso varied widely from place to place.
In constructing the new system, the French began by setting up a unitof distance equal to one forty-millionth part of the earth's circumference(?2?ü). Unfortunately, later measurements showed that the unit designed wasnot exactly that fraction, but they continued to use it. (Today the unit isdefined simply as the distance between two marks on a platinumiridium (2??e)bar kept in a suburb of Paris). The unit is the meter, and the system ofmeasurements based on this unit is the metric system, the system today usedby scientists the world over.
The metric system is built in units of ten, Greek prefixes showingmultiples and Latin prefixes showing fractions. The Greeks had no word for anumber larger than ten thousand and the Romans had none for a number largerthan one thousand, but the system was extended by using less specific words;for instance megameter (one million meters) is derived from a Greek word thatmeans simply"large".
86. The French constructed a new system of weights and measures because
_______.
A) their system did not conform to other
