Critical Reasoning (CR) | Re: Blood banks will shortly start to screen all donors for NANB hepatitis

Inference-based question - so let's jump to the option elimination -

A) The incidence of new cases of NANB hepatitis is likely to go up by 10 percent. - We don't know. How about if earlier, all these 15% were donating, but now the 5% are filtered at the source, so the cases should actually go down? So, it may or may not be true. Such options are not true on Inference.

B) Donations made by patients specifically for their own use are likely to become less frequent. - Is there anything like this mentioned in the passage (In inference questions no new information please, we have to stick to the argument). Out of scope.

C) The demand for blood from blood banks is likely to fluctuate more strongly. - We don't know. The argument just talks about the supply side of the equation. Anything mentioned on the demand side? No. Out of scope.

D) The blood supplies available from blood banks are likely to go down. - Perfect. Earlier suppose 100 blood brackets were in the blood bank. Now 95. Number
