Which sentence would provide the best commentary to support the writer’s argument?

The complete question is:

Read the passage from a student's response to an op-ed

It is long past time that this town install bike lanes on  our main streets. Our downtown area is congested and  chaotic. Bike lanes help calm traffic by slowing cars, reducing the number of drivers on the streets, and confining cyclists to dedicated lanes. Dedicated bike lanes also free up sidewalk space for pedestrians. And of course, studies show that lanes protected by physical barriers decrease the frequency of accidents  between cyclists and motor vehicles.

Which sentence would provide the best commentary to support the writer’s argument?

- It is clear that bike lanes make streets safer for everyone in the community.

Explanation:

The above sentence proffers the most adequate remark in order to back the author's argument that the installation of exclusive bike lanes has been really helpful for the community as it makes the streets safer and convenient to access. The descriptions regarding the bike lanes assisting in reduced traffic and congestion, liberating the side space for pedestrians, and a lower density of accidents further substantiate the author's point that these lanes have helped in making the main streets quite guarded and safe for the people living in the community.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
