Question 25 • Earth and Space Science

What trend is observed in the data, and what does it suggest?

Answer
A
The larger the parallax angle, the farther the star is from Earth.
B
The smaller the parallax angle, the farther the star is from Earth.
C
The parallax angle and distance increase in proportion to one another.
D
The parallax angle does not relate to distance.

Explanation

Parallax angle and distance have an inverse relationship: as a star’s distance increases, its parallax angle becomes smaller. This means the data suggest that stars with smaller parallax angles are farther from Earth, matching choice B. Choices A and C reverse or misstate this relationship.
