Passage: 'After the city installed CCTV cameras at major intersections last year, the number of reported road accidents fell by 18 per cent. We can therefore conclude that CCTV cameras have made our roads safer.' Which of the following, if TRUE, MOST weakens the argument?
AOver the same period, the city ran an intensive public-awareness campaign about safe driving and increased traffic-police presence on the same intersections
BCCTV cameras have a useful life of seven years
CThe cameras were purchased from a foreign supplier
DThe cameras were installed on 1 January last year
Answer & Solution
Correct answer: A. Over the same period, the city ran an intensive public-awareness campaign about safe driving and increased traffic-police presence on the same intersections
A confounding variable (the awareness drive + extra police) provides an alternative explanation for the fall. The argument confused correlation with causation, and this option supplies the rival cause.
