A spherical representation of the earth?

• A. Terrestrial Globe
• B. Globe
• C. Map
• D. Astronomy

Answer: (A)

The idea being tested is naming a three‑dimensional model of the Earth. A globe is a spherical representation of the world, and adding the word terrestrial specifies that it is Earth itself (as opposed to a celestial globe, which represents the sky or stars). This makes terrestrial globe the most precise term for a spherical model of the Earth. A map is flat, not spherical, and astronomy is the study of celestial bodies, not a model of Earth.
