Question

a cyclist chooses a bike at a bike - sharing station.
bike boom
the more bike - friendly a city becomes, the more people ride. in fact, after cities build protected bike lanes, the number of people riding bikes often doubles.
bike lanes can make traffic safer for everyone, not just cyclists. cars slow down and drive more carefully next to bike lanes. people studying bike safety watched videos of almost 13,000 riders at city intersections with bike lanes. they didnt see a single accident. and when cyclists have their own lanes, they dont ride on the sidewalk, so the people walking stay safer, too.
cities have good reasons to like bikes. more bicycles on the road means there arent as many people driving, which means less traffic and pollution. and thats good for the earth and all its people, on two wheels or four.
what new point does the author make in the last paragraph?

• traffic and pollution problems can be fixed in cities.
• cities are taking steps to support all bikers.
• cities should replace cars with more bikes.
• biking instead of driving in cities helps people and our planet.

Explanation:

The last paragraph of the passage "Bike Boom" states that more bicycles on the road lead to fewer people driving, which reduces traffic and pollution, and this is good for the Earth and people. The option "Biking instead of driving in cities helps people and our planet" aligns with this idea. The other options: "Traffic and pollution problems can be fixed in cities" is too general and not the specific new point here; "Cities are taking steps to support all bikers" is not mentioned in the last paragraph; "Cities should replace cars with more bikes" is a misinterpretation as the passage says more bikes lead to fewer cars, not a full replacement.

Answer:

D. Biking instead of driving in cities helps people and our planet. (assuming the options are labeled A - D in order, with D being the last option about helping people and the planet)
