In the United States, nearly half of the whole blood received by blood banks is acquired by buying blood from “donors.” This is a dangerous practice. It increases the risk of hepatitis for recipients because people who have the disease and who are desperate for money may lie in order to sell their blood. The practice is also demonstrably inefficient because the people willing to sell blood may not have the blood types needed. Finally, it commercializes what can be a beautifully rewarding act.

The portions in boldface play which of the following roles?

(A) The first is the overall conclusion of the argument; the second is support for that conclusion.

(B) The first is support for the overall conclusion of the argument; the second is one part of the overall conclusion.

(C) The first is support for the overall conclusion of the argument; the second undermines that overall conclusion.

(D) The first is one part of the overall conclusion of the argument; the second is support for another part of the overall conclusion.

(E) The first is one part of the overall conclusion of the argument; the second is another part of the overall conclusion.

Spoiler: :: OE
As in any boldface CR problem, you should first read all elements of the argument to understand it generally and then hone in on the boldfaced portions. In this argument, the first sentence simply provides context for what follows. The first boldfaced portion “This is a dangerous practice” appears to be the main conclusion of the argument. If you ask “why” to that statement it leads you to the evidence that immediately follows: Why is it dangerous? Because “It increases the risk of hepatitis for recipients because people who have the disease and who are desperate for money may lie in order to sell their blood.” However the beginning of the next sentence “The practice is ALSO demonstrably inefficient” does NOT support “This is a dangerous practice” and you must realize this is another part of the conclusion (evidenced by the word “also”) This part of the conclusion is supported by the second boldfaced portion, as that portion gives a reason why the buying blood is inefficient. The last sentence is the final part of the conclusion for which no support or evidence is given.

So the overall conclusion of the author is that buying blood is dangerous, inefficient, and commercializes what can be a beautifully rewarding act. With that in mind you can then analyze each answer choice:

(A) Incorrect. The first portion is not the overall conclusion but rather part of it. The second part does not give any support for the conclusion that “This is a dangerous practice.”

(B) Incorrect. Since you might consider the overall conclusion to be “buying blood is a bad idea”, the first part of this answer choice could be correct. However, the second boldfaced portion is clearly support; it is NOT part of the overall conclusion.

(C) Incorrect. Since you might consider the overall conclusion to be “buying blood is a bad idea”, the first part of this answer choice could be correct. However, the second boldfaced portion does not undermine the overall conclusion but supports it.

(D) CORRECT. The first boldfaced portion is part of the overall conclusion and the second provides support for the statement that “the practice is also demonstrably inefficient”, which is part of the overall conclusion.

(E) Incorrect. The first boldfaced portion is part of the overall conclusion but the second is NOT another part of the conclusion – rather it provides support for that part.

I marked A. According to me,the first boldface is the main conclusion.The argument further provides evidence as to why 'This is a dangerous practice'. Please help as to what is the actual conclusion of the argument.

This is a dangerous practice.
-> this is one part of overall conclusion

The practice is also demonstrably inefficient
-> this is second part of overall conclusion

2nd bold faced part provides reason/support for above second conclusion

D correctly states that

E. The first is one part of the overall conclusion of the argument; the second is another part of the overall conclusion.


Premise 1:In the United States, nearly half of the whole blood received by blood banks is acquired by buying blood from “donors.”

Premise 2:This is a dangerous practice. It increases the risk of hepatitis for recipients because people who have the disease and who are desperate for money may lie in order to sell their blood.

Premise 3:The practice is also demonstrably inefficient because the [b]people willing to sell blood may not have the blood types needed

Premise 4 :Finally, it commercializes what can be a beautifully rewarding act.

Conclusion :Receiving blood directly from donors is a dangerous practice and it commercializes what can be a beautifully rewarding act.

Bold sentence "This is a dangerous practice" refers to the collection of blood by the bank from the donors , so it is a part of the conclusion.
Second bold statement on the other hand gives support for the conclusion that the practice is not very useful.

Option D:
It can be clearly observed that the second bold statement is a support and not a conclusion as it gives a reason for a statement. This leaves us with choices A and D.
Between A and D, it is easy to point out the correct answer as both the bold statements are different parts of overall conclusion that buying/ selling practice of blood is bad.

Hit kudos if it helped.
