Which term is a common job title for someone who studies space?

• A. Astronomer
• B. Authentic
• C. Stumble Upon
• D. Wedged

Answer: (A)

Studying space is the domain of astronomy, and the person who pursues that field is called an astronomer. An astronomer uses telescopes and other data to observe celestial objects, analyzes light and signals from space, and builds models to understand planets, stars, galaxies, and the universe as a whole. The other options don’t fit because they’re unrelated words: authentic means genuine, stumble upon refers to finding something by chance, and wedged describes something stuck or tightly placed, not a profession.
