Height Comparison and Grammar Usage

This question requires us to select the most appropriate comparative adjective to describe the difference in vertical measurements, specifically human height, between Mr. X and Mr. Y. We need to choose the option that aligns with standard English grammar and common usage for comparing heights.

Understanding the Provided Height Statements

We are given two statements regarding the heights of Mr. X and Mr. Y:

• Statement (i): The height of Mr. X is 6 feet.
• Statement (ii): The height of Mr. Y is 5 feet.

From these statements, it is evident that Mr. X's height (6 feet) is greater than Mr. Y's height (5 feet). Now, we must determine the correct word to express this difference in height.

Analyzing Comparative Adjectives for Height

When comparing the vertical dimension of people or objects that stand upright, specific comparative adjectives are used. Let's examine each of the provided options:

• Option 1: "Mr. X is longer than Mr. Y."

  The adjective "longer" is the comparative form of "long." "Long" is typically used to describe horizontal extent, distance, or duration (e.g., "a long river," "a long journey," "a long time"). It is not the standard or appropriate term for comparing the vertical height of individuals.

• Option 2: "Mr. X is more elongated than Mr. Y."

  The word "elongated" means stretched out or lengthened. While it relates to length, "more elongated" is an uncommon and unnatural way to compare human heights. It often suggests a change in shape or a stretched appearance rather than a simple comparison of vertical measurement, and it is not typically used for direct height comparisons between people.

• Option 3: "Mr. X is taller than Mr. Y."

  The adjective "taller" is the comparative form of "tall." "Tall" is specifically used to describe a great height, especially of people, buildings, or trees, or other objects that extend significantly upwards. Therefore, "taller" is the grammatically correct and most appropriate term to use when comparing the vertical height of two individuals.

• Option 4: "Mr. X is lengthier than Mr. Y."

  The adjective "lengthier" is derived from "lengthy," which means very long, often used for things like speeches, reports, or processes that consume a lot of time or space in a discursive sense. It is not an appropriate term for describing the physical vertical height of a person.

Conclusion on Correct Usage

Considering that Mr. X's height is 6 feet and Mr. Y's height is 5 feet, Mr. X is indeed greater in vertical stature. Based on standard English grammar and common usage for describing human height, "taller" is the only correct and natural comparative adjective among the given choices. Therefore, the statement "Mr. X is taller than Mr. Y" accurately and appropriately describes the situation.
