A wildlife expert predicts that the reintroduction of the caribou into the northern Minnesota would fail if the density of the timber wolf population in that region is more than one wolf for every 39 square miles.

I understand that density is countable so we should use greater than, but in the flash cards I find this "greater than, More than" concept: "More than should be used when describing the numbers of objects" and " Greater than should be used when describing numbers alone" -- going be this i feel we should use More than in the sentence above because this sentence is about the wolf ( or the object ).

Please help me out with this confusion..

Well i assume that you already got the answer but need more clarity for other concepts.

This is correct:
"More than should be used when describing the numbers of objects" and " Greater than should be used when describing numbers alone"

E.g. % 5 apples are more than 3 apples
5 is greater than 3

Now coming to case in ques.
"one wolf for every 39 square miles" is actually a ratio, more precisely a statistic.
You took it as "one wolf" and thought of using "more" which is correct if that had been the case BUT here we are comparing a statistic which is similar to comparing a statistic. So we use "greater than"
Premise: If you like my post
Conclusion : Press the Thanks Button ;)
