Blood banks will shortly start to screen all donors for NANB hepatitis...
Introduction:
The passage states that blood banks will begin screening all donors for NANB hepatitis. While the new screening tests are estimated to disqualify up to 5 percent of all prospective blood donors, they will still miss two-thirds of donors carrying NANB hepatitis. As a result, it is inferred that about 10 percent of actual donors will still supply NANB-contaminated blood. Based on this information, the best-supported inference about the consequences of instituting the new tests is that the blood supplies available from blood banks are likely to go down.

Reasoning:
Let's analyze the information provided in the passage to support the inference that the blood supplies available from blood banks are likely to go down:

1. New screening tests disqualify up to 5% of prospective blood donors: The passage states that the new screening tests are estimated to disqualify up to 5% of all prospective blood donors. This implies that a portion of the donor pool will be ineligible to donate blood due to the screening results.

2. New screening tests miss two-thirds of donors carrying NANB hepatitis: The passage also mentions that the new screening tests will still miss two-thirds of donors carrying NANB hepatitis. This implies that even though the tests are implemented, a significant number of donors with NANB hepatitis will go undetected.

3. About 10% of actual donors will still supply NANB-contaminated blood: The passage concludes that approximately 10% of actual donors will still supply NANB-contaminated blood despite the new screening tests. This indicates that a significant portion of the blood supply will still be contaminated with NANB hepatitis.

Inference:
Based on the information provided, the best-supported inference is that the blood supplies available from blood banks are likely to go down. This is because the new screening tests will disqualify a percentage of prospective donors and will miss a significant number of donors carrying NANB hepatitis, resulting in a decrease in the overall blood supply.

Blood banks will shortly start to screen all donors for NANB hepatitis...
(A) The incidence of new cases of NANB hepatitis is likely to go up by 10 percent:
  • The passage does not provide any information about the incidence of new cases of NANB hepatitis. It only mentions the potential percentage of actual donors supplying contaminated blood, which does not directly imply an increase in new cases.
(B) Donations made by patients specifically for their own use are likely to become less frequent:
  • The passage does not mention anything about donations made by patients for their own use. It focuses on blood donors and the potential contamination of blood supplies.
(C) The demand for blood from blood banks is likely to fluctuate more strongly:
  • The passage does not provide any information about the potential fluctuation in demand for blood. It mainly discusses the screening tests and their impact on the supply of contaminated blood.
(D) The blood supplies available from blood banks are likely to go down:
  • This is the best-supported inference based on the passage, as explained above.
(E) The number of prospective first-time donors is likely to go up by 5 percent:
  • The passage does not mention anything about the number of prospective first-time donors. It only discusses the potential disqualification of donors and the contamination of blood supplies.
In summary, the best-supported inference is that the blood supplies available from blood banks are likely to go down (option D).

Similar GMAT Doubts

The accumulation of scientific knowledge regarding the environmental impact of oil well drilling in North America has tended to lag behind the actual drilling of oil wells. Most attempts to regulate the industry have relied on hindsight: the need for regulation becomes apparent only after undesirable events occur. The problems associated with oil wells’ potential contamination of groundwater—fresh water within the earth that supplies wells and springs—provide a case in point.When commercial drilling for oil began in North America in the mid-nineteenth century, regulations reflected the industry’s concern for the purity of the wells’ oil. In 1893, for example, regulations were enacted specifying well construction requirements to protect oil and gas reserves from contamination by fresh water. Thousands of wells were drilled in such a way as to protect the oil, but no thought was given to the possibility that the groundwater itself might need protection until many drinking-water wells near the oil well sites began to produce unpotable, oil contaminated water.The reason for this contamination was that groundwater is usually found in porous and permeable geologic formations near the earth’s surface, whereas petroleum and unpotable saline water reservoirs are generally found in similar formations but at greater depths. Drilling a well creates a conduit connecting all the formations that it has penetrated. Consequently, without appropriate safeguards, wells that penetrate both groundwater and oil or saline water formations inevitably contaminate the groundwater. Initial attempts to prevent this contamination consisted of sealing off the groundwater formations with some form of protective barrier to prevent the oil flowing up the well from entering or mixing with the natural groundwater reservoir. This method, which is still in use today, initially involved using hollow trees to seal off the groundwater formations; now, however, large metal pipe casings, set in place with cement, are used.Regulations currently govern the kinds of casing and cement that can be used in these practices; however, the hazards of insufficient knowledge persist. For example, the long-term stability of this way of protecting groundwater is unknown. The protective barrier may fail due to corrosion of the casing by certain fluids flowing up the well, or because of dissolution of the cement by these fluids. The effects of groundwater bacteria, traffic vibrations, and changing groundwater chemistry are likewise unassessed. Further, there is no guarantee that wells drilled in compliance with existing regulations will not expose a need for research in additional areas: on the west coast of North America, a major disaster recently occurred because a well’s location was based on a poor understanding of the area’s subsurface geology. Because the well was drilled in a channel accessing the ocean, not only was the area’s groundwater completely contaminated, but widespread coastal contamination also occurred, prompting international concern over oil exploration and initiating further attempts to refine regulations.The passage states which one of the following about underground oil reservoirs?

For millennia, the Nile River flooded nearly every year as a natural consequence of heavy summer rains on the Ethiopian Plateau; in the last century, as the population in the region exploded, the cycle of flooding interspersed with periodic drought caused widespread suffering for the local population. In the mid-1950s, the Egyptian government concluded that a significant dam was necessary to enable the country’s economic development to be on a par with that of Western nations. The Aswan Dam would prevent the annual flooding, generate hydroelectric power and supply a steady source of water for residents and agricultural activities, though it would also have other, less positive effects.By the 1970s, most Egyptian villages had electric power, and the dam provided approximately half of Egypt’s entire output of electricity. The benefits were counteracted, however, by consequences which were sometimes slow to appear but ruinous in their long-term effects. Dams prevent silt from flowing through to downstream lands.The silt is essential for renewing the minerals and nutrients that make the land fertile; before the dam, the Nile floodplain was famously productive. Farmers have had to substitute artificial fertilizers, reducing profits and causing pervasive chemical pollution with deleterious effects for the human, animal and plant populations living near or in the river. It is difficult to draw definite conclusions about a project with such substantial and varied results, but it would be untenable to assert that the Egyptian government should never have built the Aswan Dam.Q.Based upon the content of the passage, the author would most likely agree with which of the following propositions?
