Answer:
The correct answer is Great care was taken to keep the truth from the public.
Step-by-step explanation:
The ambulance members were trying not to be seen by any person when they were going to the monkey house. That's why they wore camouflaged suits, and no member of the ambulance wore the suit they should be wearing.
They even parked in the backyard of the house to avoid being seen.
All this is evidence that they wanted to hide the truth from the public.
