Concept

Literal-comprehension questions are answered from statements explicitly present in the passage. The reader should identify the phrase that matches an option and avoid replacing the author’s framing with outside factual knowledge.

Application

The passage describes humanity’s long effort to learn more about the face of the earth as the human habitat. Thus, within the passage, the earth is framed as the setting in which human beings live and build knowledge.

Contrast

• A globe is a spherical model used to represent the earth; the passage does not adopt this cartographic framing.

• A celestial body is a broad astronomical category; the passage focuses on human observation and experience rather than astronomical classification.

• A planet is an astronomical object orbiting a star; that scientifically true classification is not the role assigned to the earth in the passage.

Cross-check

The same paragraph connects knowledge of the earth with human perception, concepts, and scholarly observation. This context consistently treats the earth as the environment of human life.

Result

Therefore, the earth is taken as the human habitat.
