Comparative with collective nouns: choose the correct phrasing when comparing populations Original sentence: "The population of Tokyo is greater than that of any other town in the world." Select the best option; if the original is correct, choose "No correction required".

Reasoning
When comparing the population of one city with others, we avoid repeating “population” by using the pro-form “that (population)”. Hence: “greater than that of any other town …” is correct and precise.

Why alternatives are wrong

• “greatest among any other” — mixes superlative with “any other,” which is ungrammatical.
• “greater than all other” — would need “the populations of all other towns,” and still less precise than the original.
• “those of any other” — plural “those” mismatches the singular “population”.
• “greater than any other” — compares Tokyo (a city) with “any other” city, not their populations; comparison is ill-formed.

Final Answer
No correction required.
