How could a humble tortoise beat the legendary Greek hero Achilles in a race? The Greek philosopher Zeno liked a challenge and came up with this paradox. First, the tortoise is given a slight head start. Anyone fancying a flutter would still rush to put their money on Achilles. But Zeno pointed out that, to overtake him, Achilles would first have to cover the distance to the point where the tortoise began. In that time the tortoise would have moved – so Achilles would have to cover that distance, giving the tortoise time to amble forwards a bit more. Logically this would carry on forever. However small the gap between them, the tortoise would still be able to move forwards while Achilles was catching up. Meaning that Achilles could never overtake.
From the context, I think challenges (plural form) should be used to generally describe what kind of person Zeno is and then give specific example — came up with this paradox... I think this is more logical. It seems that liked a challenge has a plural meaning, but I feel very puzzled.
We say “I like flowers” = flowers generally. We don’t say “I like a flower” to describe flowers in general. Why is challenge different?
