While none of the answers is what I consider the main idea of this essay, I believe that C is the best possible answer. Each of the paragraphs discusses how particular groups are impacted by the use of lights in urban areas.

Value of a is 4 and value of line YZ is 20 units
Given:
Y is between point X and Z
Value of line XY = 7a
Value of line YZ = 5a
Value of line XZ = 6a + 24
Value of "a" and line YZ
We know that
XY + YZ = XZ
So,
7a + 5a = 6a + 24
12a = 6a + 24
6a = 24
a = 4
Value of a = 4
So,
Value of line YZ = 5a
By putting value of a
Value of line YZ = 5(4)
Value of line YZ = 20 units
