For the average person who needs a transfusion, blood from a relative is more likely to be infected with hepatitis than is blood from a blood bank. Therefore, the risk of contracting hepatitis from a transfusion is higher for people receiving blood from relatives than for people receiving blood from blood banks.
Which one of the following, if true, most seriously weakens the argument?
  • a)
    People receiving blood transfusions often specify that blood from their relatives be used.
  • b)
    Blood transfusions only rarely result in the recipient being infected with hepatitis.
  • c)
    Blood taken from a relative is highly likely to match a transfusion recipient’s blood type.
  • d)
    Donors to blood banks are always asked whether they have ever been infected with hepatitis.
  • e)
    Blood that is to be used in a transfusion is always screened for hepatitis.
Correct answer is option 'E'. Can you explain this answer?

For the average person who needs a transfusion, blood from a relative ...
Understanding the Argument
The argument suggests that blood from relatives carries a higher risk of hepatitis infection compared to blood from blood banks. Therefore, it concludes that individuals receiving transfusions from relatives face a greater risk of contracting hepatitis.
Key Points of the Argument
- Blood from relatives is more likely to be infected with hepatitis.
- Blood bank donations are considered safer.
- The conclusion implies a higher risk for transfusions from family members.
Why Option E Weakens the Argument
Option E states that "Blood that is to be used in a transfusion is always screened for hepatitis." This information significantly impacts the argument in the following ways:
- Screening Reduces Risk: If all blood intended for transfusions is screened, then the risk of hepatitis infection is mitigated, regardless of the source (relative or blood bank). This undermines the assertion that blood from relatives is inherently more dangerous.
- Equalizing Risk Factors: The screening process means that both blood types are subjected to the same safety protocols, thus reducing the overall risk of infection from both sources.
- Shifts Focus from Source to Process: The argument fails to consider that the method of blood collection and processing (screening) is crucial in determining safety, not just the source of the blood.
In conclusion, by highlighting the universal screening of transfusion blood, option E effectively challenges the basis of the argument, demonstrating that the risk of hepatitis is not necessarily higher for blood from relatives compared to blood from banks.

For the average person who needs a transfusion, blood from a relative ...
(A) People receiving blood transfusions often specify that blood from their relatives be used.
This option does not weaken the argument. If people frequently request blood from their relatives, it supports the premise that blood from relatives is more likely to be used in transfusions.
(B) Blood transfusions only rarely result in the recipient being infected with hepatitis.
This option weakens the argument by challenging the premise that blood from relatives is more likely to be infected with hepatitis. If blood transfusions rarely result in hepatitis transmission regardless of the source, it undermines the idea that blood from relatives poses a higher risk.
(C) Blood taken from a relative is highly likely to match a transfusion recipient's blood type.
This option does not weaken the argument. While it provides information about blood type matching, it does not address the issue of hepatitis infection, which is the focus of the argument.
(D) Donors to blood banks are always asked whether they have ever been infected with hepatitis.
This option does not weaken the argument. Asking blood donors about hepatitis infection helps ensure the safety of blood donations but does not directly address the comparison between blood from relatives and blood from blood banks.
(E) Blood that is to be used in a transfusion is always screened for hepatitis.
This option weakens the argument by presenting a safety measure that applies to all blood used in transfusions, regardless of the source. If all blood used in transfusions is screened for hepatitis, it suggests that the risk of contracting hepatitis is mitigated, regardless of whether the blood comes from relatives or blood banks.
Therefore, option (E) most seriously weakens the argument by highlighting that all blood used in transfusions is screened for hepatitis, reducing the risk of infection regardless of the source.
