This major breakthrough was the identification of the cause and spread of the disease yellow fever. For several centuries, yellow fever(2) was a scourge upon societiesin various parts of the world, striking towns and killing thousands of people.(3) Thanks tothe efforts of Major Walter Reed and many courageous volunteers, the mechanisms for contracting and spreading yellow fever were uncovered.During Reed’s lifetime, it was(4) a common acceptancethat yellow fever was spread by contact with infected(5) items; such asthe clothing or blankets of a person with yellow fever. Some doctors, however, questioned this notion, as the spread of yellow fever was not consistentwith the spread of other communicable diseases.(6)Doubts about the accepted(7) theory’sof the fever’s spread prompted the U.S. Army to assign Reed and several doctors to the problem. They studied yellow fever in Cuba, where(8) they wereinfecting soldiers fighting in the Spanish American War at(9) a discouraging rate.Acting on a hunch, several doctors volunteered to be bitten by mosquitoes; the volunteers developed yellow fever. This was enough information to spur General Reed to conduct more comprehensive(10) experiments, so helping his cause.American and Spanish soldiers were paid to participate in these experiments, but some participants wanted only to advance science and refused the money.The experiments began with the construction of a building in which men who did not have yellow fever were housed. These men were placed in contact with clothing that(11) have been wornby yellow fever victims. Not one of it these men contracted the(12) fever. Asecond building was constructed with two sides separated bya screen. An infected volunteer lived on one side, and more volunteers lived on the other side, where they were completely protected from mosquitoes. This experiment was(13) repeatablemany times, and the volunteers who were protected from mosquitoes never contracted the fever.(14)As a result of his findings and of the bravery of the volunteers, measures were taken to control the mosquito population and to keep the insects away from people. Eventually a vaccine was developed,(15) which reduced further the outbreaks of yellow fever incidences.Q. (6)Which of the following sentences, if inserted here, would be the best example of how yellow fever seemed to be spread differently than other communicable diseases?a)For example, people had no choice but to wear clothing and use blankets, so the fever could not have spread that way.b)For example, sometimes one person would get sick in a household, while nobody else in that household would get sick.c)For example, yellow fever caused a great deal of pain in its victims.d)For example, some doctors were willing to go against what the rest of the medical establishment was saying.Correct answer is option 'B'.
