Which term names the spiral galaxy that contains Earth and the Sun?

• A. Milky Way
• B. Galaxy
• C. Solar System
• D. Star

Answer: (A)

The main idea is identifying the specific spiral galaxy that includes Earth and the Sun. Our solar system sits inside the Milky Way, which is a spiral-shaped collection of hundreds of billions of stars. A galaxy is a huge system of stars, gas, and dark matter; naming it “the galaxy” is too general. A solar system refers to the Sun and its planets, not the whole galaxy. A star is an individual luminous object, not a group. Since the spiral galaxy that contains Earth and the Sun is called the Milky Way, that is the correct term. Remember, the Milky Way is our home galaxy, a spiral type among other galaxy shapes.
