Reading Passage Question
A few months ago, the village of Queniborough and its surroundings in Leicestershire gained dubious distinction as Britain’s hot spot for variant Creuzfeldt-Jakob disease (vCJD), a fatal neurodegenerative condition related to bovine spongiform encephalopathy (BSE)—better known as mad-cow disease. Out of 95 cases of vCJD reported in Britain since 1995, five occurred there. This clustering of cases has proved a boon to epidemiologists trying to grips with the elusive origin and spread of vCJD. A team of government experts announced what it believes may lie at the heart of the Leicestershire vCJD outbreak: consumption of meat contaminated with BSE-infected brain tissue.
That may be no great surprise, but according to Gerry Bryant, one of the investigators, this is the first clear demonstration of an association between vCJD and BSE through diet. The authorities ruled out blood transfusions, vaccines, and occupational exposure, as the five victims did not share these. However, they found that the victims had all bought meat from a handful of local butchers who either slaughtered cattle in their own back rooms or used small abattoirs nearby. Unlike the large abattoirs employed by supermarkets, these operations practiced “pithing” ramming a rod through an animal’s brain to squash the spinal cord. This rough and ready procedure (which has since been banned) allows bits of the brain to leak out and contaminate other tissues.
Local slaughter houses also regularly removed the brains of beef cattle to sell and used the same knives for other butchery tasks—an obvious source of cross contamination. The study has found that those with the disease were 15 times more likely to have bought and consumed beef from a butcher where such cross-contamination may have occurred than were those living in the same area who did not develop the disease. The link between diet and vCJD will set alarms ringing across Britain. It will also worry people in the rest of Europe. How many more will appear and where is hard to say. As Dr. Will cautions, the Leicestershire findings are an essential step forward in the vCJD study. But, researchers still have more questions than answers when it comes to vCJD.

It gained recognition as Britain’s hot spot for variant Creuzfeldt-Jakob disease. This is a fatal neurodegenerative condition related to bovine spongiform encephalopathy (BSE), known as mad-cow disease. The author adds that the clustering of cases has proved a boon to epidemiologists trying to deal with the elusive origin and spread of vCJD.
Answer: C
Explanation: The passage according to Gerry Bryant, the first clear demonstration of an association between vCJD and BSE through diet. Here "The first clear demonstration" in the above-quoted text refers to that there might be some hidden or un-documented cases. The connection between vCJD and BSE through diet was clear. So, a possibility could be some existing cases of the same. So, option C is the correct answer.
Answer: B
Explanation: The passage states that in 1995 out of 95 cases of vCJD reported in Britain five occurred. The clustering of cases has proved to be a boon to epidemiologists. A team of government experts proclaimed it may lie at the heart of the Leicestershire vCJD outbreak. Hence option B stating about striking of the brain is not mentioned in the passage. Hence option B is the correct answer.
Answer: A
Explanation: The paragraph 1 in the passage states that a village of Queniborough and its surroundings in Leicestershire became Britain’s hotspot for variant Creuzfeldt-Jakob disease. The 2nd paragraph in the passage states that one of the investigators demonstrated an association between vCJD and BSE through diet. The third paragraph deals with the disease where 15 times more likely to have bought and consumed beef from a butcher. It further adds that cross-contamination may have occurred, hence, the development of the disease. Hence option A is the correct answer.
