Which line describes standing guard day and night?

• A. Standing guard both night and day
• B. We're the mighty watchful eye
• C. The Space Force from on high
• D. Boldly reaching into space

Answer: (A)

Constant vigilance carried out around the clock is being tested here. The line “standing guard both night and day” states the action directly and ties it to every part of the day, conveying continuous duty without ambiguity. That explicit pairing of the act with the full time span makes it the clearest description of standing guard at all times. The other lines shift emphasis—one leans into imagery of vigilance, another points to the Space Force as an entity, and another focuses on exploration—none of which directly express the act of guarding continuously.
