ANSWER QUICKLY PLEASE This is an excerpt from How the Other Half Lives written by Jacob Riis in 1890.

In New York…three-fourths of its people live in the tenements, and the nineteenth century drift of the population to the cities is sending ever-increasing multitudes to crowd them. The fifteen thousand tenant houses that were the despair of the sanitarian in the past generation have swelled into thirty-seven thousand, and more than twelve hundred thousand persons call them home. The one way out he saw—rapid transit to the suburbs—has brought no relief. We know now that there is no way out; that the “system” that was the evil offspring of public neglect and private greed has come to stay, a storm-center forever of our civilization. Nothing is left but to make the best of a bad bargain.
Based on this excerpt, why did Riis believe that cities like New York became centers for poverty?

A. The availability of quality affordable housing brought more people to cities.
B. The lack of public transportation to suburbs kept people from leaving cities.
C. The development of ethnic neighborhoods led to little collaboration among people.
D. The greed of business owners led to more low-wage workers than cities could handle.
