Detroit remains one of the most racially segregated cities in the United States. From the 1940s to the 1970s a second wave of Blacks moved to Detroit to escape Jim Crow laws in the south and find jobs. However, they soon found themselves excluded from white areas of the citythrough violence, laws, and economic discrimination (e.g., redlining). White residents attacked black homes: breaking windows, starting fires, and exploding bombs. The pattern of segregation was later magnified by white migration to the suburbs. One of the implications of racial segregation, which correlates with class segregation, may be overall worse health for some populations.
What exacerbated segregation in Detroit?
****
The answer: white migration to the suburbs

The range is mostly located in the United States but extends into southeastern Canada, forming a zone from 100 to 300 mi (160 to 480 km) wide, running from the island of Newfoundland 1,500 mi (2,400 km) southwestward to Central Alabama in the United States.[discuss] The range covers parts of the islands of Saint Pierre and Miquelon, which comprise an overseas territory of France. The system is divided into a series of ranges, with the individual mountains averaging around 3,000 ft (910 m). The highest of the group is Mount Mitchell in North Carolina at 6,684 feet (2,037 m), which is the highest point in the United States east of the Mississippi River.
What island is included in the range?
****
The answer: Saint Pierre and Miquelon

The problem: Answer a question about this article:
Chinese characters are primarily morphosyllabic, meaning that most Chinese morphemes are monosyllabic and are written with a single character, though in modern Chinese most words are disyllabic and dimorphemic, consisting of two syllables, each of which is a morpheme. In modern Chinese 10% of morphemes only occur as part of a given compound. However, a few morphemes are disyllabic, some of them dating back to Classical Chinese. Excluding foreign loan words, these are typically words for plants and small animals. They are usually written with a pair of phono-semantic compound characters sharing a common radical. Examples are hudie "butterfly" and shanhu "coral". Note that the hu of hudie and the hu of shanhu have the same phonetic, , but different radicals ("insect" and "jade", respectively). Neither exists as an independent morpheme except as a poetic abbreviation of the disyllabic word.
What have the same phonetic, but different radicals?
****
The answer:
hu of hudie and the hu of shanhu
