Science columnist: It is clear why humans have so many diseases in common with cats. Many human diseases are genetically based, and cats are genetically closer to humans than are any other mammals except nonhuman primates. Each of the genes identified so far in cats has an exact counterpart in humans. Which one of the following, if true, most weakens the science columnist's explanation for the claim that humans have so many diseases in common with cats?

विकल्प

• Cats have build up resistance to many of the diseases they have in common with humans.

• Most diseases that humans have in common with cats have no genetic basis.

• Cats have more diseases in common with nonhuman primates than with humans.

• Many of the diseases humans have in common with cats are mild and are rarely diagnosed.

Answer 1

Most diseases that humans have in common with cats have no genetic basis.

Explanation:

'Most diseases that humans have in common with cats have no genetic basis.' weakened because it states that the diseases that humans and cats have in common are not genetic in nature. Thus, it negates the science columnist’s reasoning of humans and cats having similar diseases because of their genetic similarity.
