Which clue signals human activity along the path found by Lina?

• A. Tire tracks
• B. Fresh fish remains
• C. Campsite tents
• D. Bright paint marks

Answer: (A)

The important idea is recognizing evidence that someone has moved through a route. Tire tracks on the path are a direct sign that a vehicle traveled there, showing recent human activity along Lina’s route. The other clues can suggest people were somewhere nearby, but they don’t indicate movement along the path as clearly: campsite tents point to a place where people stayed, not necessarily that they used this specific path; fresh fish remains might come from a nearby activity near water; bright paint marks could be markers or decorations but don’t prove someone recently moved along the path itself. So tire tracks provide the clearest signal that humans have used Lina’s path.
