听力原文：Donating blood plasma has always been a noble pursuit to help those in need. Since last September, there has been an upsurge in blood donations, as the need has become more emphasized and more empathized. But if you've had a tattoo or piercing within the last year, you will more than likely be turned away from any blood bank.
When you go to a blood bank to give plasma, they ask you a series of questions to determine if you are eligible to donate. Obviously, they don't want to risk accepting contaminated blood, so they will ask about your sexual history, current health status and other related questions, including whether or not you have gotten a tattoo or piercing within the last 12 months.
All blood that is donated is screened for disease such as HIV, Hepatitis, Syphilis and other common blood- born ailments.
However, it goes without saying that it is a waste of the blood bank's and the donor's time to harvest blood that is tainted and thus worthless.
So, in order to avoid wasted time, they ask these questions to screen the potential donor. And although even I would be quick to say that tattooing and piercing are much safer than some medical professionals like to indicate, there is still always a chance of getting and carrying a disease unknowingly from a tattoo or piercing, especially Hepatitis. That has been the object of many heated arguments and stringent regulations.
If you should happen to contract a disease from a tattoo or piercing, it should show up in a screening after 12 months, which is the reason for the waiting period. Yes, maybe it's a little over-precautious, but would you want to be the one on the receiving end of dirty blood？ If there, is even a chance, it is better to be safe than sorry.

Is it possible that the ideas we have today about ownership and property rights have been so universal in the human mind that it is truly as if they had sprung from the mind of God？ By no means. The idea of owning and property emerged in the mists of unrecorded history. The ancient Jews, for one, had a very different outlook on property and ownership, viewing it as something much more temporary and' tentative than we do.
The ideas we have in America about the private ownership of productive property as a natural and universal right of mankind, perhaps of divine origin, are by no means universal and must be viewed as an invention of man rather than an order of God. Of course, we are completely trained to accept the idea of ownership of the earth and its products, raw and transformed. It seems not at all strange; in fact, it is quite difficult to imagine a society without such arrangements. If someone, some individuals, didn't own that plot of land, that house, that factory, that machine, that tower of wheat, how would we function？ What would the rules be？ Whom would we buy from and how would we sell？
It is important to acknowledge a significant difference between achieving ownership simply by taking or claiming property and owning what we tend to call the "fruit of labor." If I, alone or together with my family, work on the land and raise crops, or if I make something useful out of natural material, it seems reasonable and fair to claim that the crops or the objects belong to me or my family, are my property, at least in the sense that I have first claim on them. Hardly anyone would dispute that. In fact, some of the early radical workingmen's movements made (an ownership) claim on those very grounds. As industrial organization became more complex, however, such issues became vastly more intricate. It must be clear that in modem society the social heritage of knowledge and technology and the social organization of manufacture and exchange account for far more of the productivity of industry and the value of what is produced than can be accounted for by the labor of any number of individuals. Hardly any person can now point and say, "That--that right there--is the fruit of my labor." We can say, as a society, as a nation--as a world, really--that what is produced is the fruit of our labor, the product of the whole society as a collectivity.
We have to recognize that the right of private individual ownership of property is man-made and constantly dependent on the extent to which those without property believe that the owner can make his claim, dependent on the extent to which those without stick.
According to the passage, the concept of ownership probably ______.
A．resulted from the concept of property right
B．stemmed from the uncovered prehistoric ages
C．arose from the generous blessing of the Creator
D．originated from the undetected Middle Ages
