After reading the paragraph, answer the question(s) that follow(s) .
Generally, we think of viruses as nasty little bits of business that arrive unwanted, take over our cellular functions, and then move along to their next victim. Recently, however, it was discovered that the human genome actually contains about half a million 'viral fossils.' Indeed, about 8% of human DNA appears to originate from viral DNA that became permanently incorporated into the human genome. And furthermore, in some cases, identical viral fossils have been found in the chimpanzee genome. These incredible findings suggest that we might need to take a broader view of how viruses and people truly interact and have done over the millennia.
-Based on these observations we might conclude that, were we able to wipe out all viruses from the face of the earth, then

A) the human race would be better off.
B) we would be removing a source of genetic variability.
C) we would rid our cells of these half a million viral DNA 'fossils.'
D) we would never be sick again.
