Verbal Ability - Sentence Correction - Discussion

It must be (d) since we don't use than any other in comparative form.

(d) can't be answer because population (size) is not greater than city (size) , we are not comparing population size to size of city. Population in Tokyo is greater than that (population) which leaves in any other city.

The answer should be A because the comparison is with the all towns of the world. So the Superlative degree must be used.

Answer can't be "A" as we use greater to compare not greatest. Option "B" and "D" compare population of tokyo with other towns so they get rejected. Although option "C" compare population with population but in comparison we take two thing at a time and in option "C" it compare population of tokyo with a group of town's population.

Superlative adjective (greatest) is used to compare more than two objectives. So I think A is answer.

Now here we are comparing population (main focus) not the town.

If population is focused than the marked answer is correct. Also, Population is uncountable noun and singular use so no use of 'Those'.

The population of Tokyo is greater than that of any other town in the world. (correct).

The other way could be:

The population of Tokyo is greatest among all other town in the world. (but that again is not any of the option).

Now lets have bottom up approach.

Option A- superlative degree used and any other refers to individual city. Greatest among any other (incorrect) greatest among all other (correct).

Option B - you can deduce from above point that it's incorrect.

Option C& D- see the first & second paragraph.

But the answer should be A Because it is comparing all the towns of the world and for comparing more than two things superlative degree should be used.

And while seeking all the towns over the world greatest word should be used.

When we compare a particular thing of a place to another place's particular thing.

This sent ace really talks about population. Even though it mentions towns, it really means the people in the town. Therefore tokyo's population is compared with other city in the world. Hence use of superlative is the grammar. Answer is A only.

I think answer should be A.

Because population of Tokyo is comparing with all the country except itself. So "Superlative degree" should be used.
