Question

Argument: The city should build more bicycle lanes because doing so will reduce traffic congestion. Which of the following, if true, most strengthens this argument?

• A. Bicycles are cheaper to own than cars.
• B. A recent survey shows many car commuters would cycle to work if dedicated, safe lanes were available.
• C. Some other cities have banned cars from their centres.
• D. Cycling regularly improves personal fitness.

Hint:

Congestion falls only if current car drivers actually switch to bikes.

Answer 1

The Correct Option is B

Step 1: Identify the claim.
The argument says new bike lanes will cut congestion. This works only if car users switch to bikes.
Step 2: Look for support of that link.
A survey showing many car commuters would cycle if safe lanes existed directly supports the switch, so congestion would fall.
Step 3: Reject the rest.
Cheaper bikes, other cities' car bans, and fitness benefits do not show that car drivers here would switch. Option 2 strengthens most.
