Which of these best describes tenements in New York City in the early 1900s?

Tenements were crowded, often poorly ventilated and unsanitary apartment buildings in New York City. They housed a very large share of the city’s residents—commonly described as about two-thirds—so choice A is the best description. Choices C and D are wrong because tenements were in the city, not outside it.
