The correct answer is 3. The road is not safe for bicycle riders, either.
Explanation
The text is an example of an essay since it tries to argue an idea through true and verifiable statements. In this case, it states that the intersection of Main Street and Wilson Lane is very dangerous. To reinforce this statement use the following arguments.
1. It is not safe at night because it only has a street lamp in the corner.
2. It is not safe for people to walk because there are no crosswalks or crosswalk signs.
3. It is unsafe because it does not have a left turn lane, causing traffic to jam when a car tries to turn left.
However, the essay does not establish a testable argument to reinforce the statement that this intersection is dangerous for cyclists because it only mentions that it is dangerous for them, but does not present strong evidence to argue it.
So the correct answer is 3. The road is not safe for bicycle riders, either.
