An argument is given, followed by three statements that either strengthen or weaken the given argument. Choose the option that correctly identifies the relationship: 'S' for strengthening and 'W' for weakening. Argument: To address increasing urban traffic congestion, a major city plans to implement a "Congestion Pricing" zone, where drivers are charged a significant fee to enter the downtown core during peak business hours. Statements:
I. Data from London and Singapore shows that similar pricing schemes resulted in a 15-20% reduction in vehicle traffic and a measurable increase in bus transit speeds.
II. Small business owners in the city center are concerned that the additional costs will deter customers, leading to a decline in retail revenue and potential store closures.
III. A recent urban planning report indicates that the city's current public transport network is already at maximum capacity and cannot accommodate a shift from private car usage.
