Verbal Ability - Sentence Correction - Discussion

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.

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.

This is a rule of parallelism when 'THAN' occurs for comparison ->
Singular noun->'THAT'.
Plural noun->'THOSE'.

Ex- Philosophy of Europeans was more rational "THAN THAT OF" Eastern Philosophers.

Gods in Greek mythology are more realistic "THAN THOSE OF" Indian mythology.

Some ppl are confused with D or E. But it z D.

When 'that' is used in the comparative sntence, other should not be used. So the answer can be.

The population of tokyo is greater than that of any town in the world or the population of tokyo is greater than any other town in the world.

Ya its so simple, in this sentence they are comparing population of Tokyo with other countries. And this is the Grammar rule If you are comparing the same thing of other country so we shall use than that of because they are comparing the population with population.

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.

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.

(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.

If the sentence will be:.

"The Tokyo is greater than any other town in the world".

Then there would be no use of that of.

But here population of Tokyo is mentioned that means that of is must be used here now.

The population will be greater than population of any other town and option [d] compares population with any other town.

Hence no correction is required. The use of that of clears the comparison.
