Answer:
Letter B
Explanation:
It is worth noting that, although poverty rates have decreased, there has been no drastic decrease as mentioned in option A and option B fits the answer better. Whereas, the official poverty rate in the USA according to data from the Census Bureau, has decreased in the last half-century, from 22.1% in 1960 to 14.5% in 2013, which means the lowest rate since the 1960s.
