A.I. Explanation:

Correct answer: land

Explanation: The word 'land' fits grammatically as it is a noun that refers to the area of ground being described. It aligns contextually with the phrase '4,000 acres of,' indicating a measurement of area. The sentence discusses the location of Pullman, making 'land' the most appropriate choice.

Meaning: 'Land' refers to the solid part of the Earth's surface, particularly in terms of property or area.

Wrong options:

• plantation: A 'plantation' refers to a large farm, especially in tropical or subtropical climates, which does not fit the context of describing a general area outside city limits.
• community: While 'community' is a noun, it refers to a group of people living in the same area, which does not describe the physical area of 4,000 acres.
• family: 'Family' is a noun that denotes a group of related individuals, which does not relate to the measurement of land.
• houses: 'Houses' refers to structures where people live, which does not fit as it does not describe the area itself.
• donations: 'Donations' refers to gifts or contributions, which is unrelated to the context of land measurement.

Meaning: 'Community' refers to a group of people living in the same place or having a particular characteristic in common.

Wrong options:
