Which fact about Ruby Decker relates to her military service?

• A. She studied abroad
• B. She served in the Army
• C. She starred in a film
• D. She opened a clinic in New York

Answer: (B)

Military service means being active in the armed forces. The statement that she served in the Army is directly about military involvement, so it clearly relates to military service. The other items describe civilian activities—studying abroad (education), starring in a film (acting), and opening a clinic in New York (medical work in civilian life)—which do not pertain to military service. So the Army service fact is the one that ties to military service.
