Show the answer and explanation
Correct answer: D
Explanation
The claim would be weaker if thefts had fallen everywhere in the area, since then something else would explain the fall.
Thefts staying level in nearby societies without cameras rules that out and points to the cameras. That strengthens the claim.
The brand of camera and residents' feelings do not show that thefts fell because of the cameras. How many families own bicycles does not show it either.
Worth noting
A strengthener often works by ruling out another explanation.
