Problem: Flowering plant:

In most taxonomies, the flowering plants are treated as a coherent group. The most popular descriptive name has been Angiospermae (Angiosperms), with Anthophyta ("flowering plants") a second choice. These names are not linked to any rank. The Wettstein system and the Engler system use the name Angiospermae, at the assigned rank of subdivision. The Reveal system treated flowering plants as subdivision Magnoliophytina (Frohne & U. Jensen ex Reveal, Phytologia 79: 70 1996), but later split it to Magnoliopsida, Liliopsida, and Rosopsida. The Takhtajan system and Cronquist system treat this group at the rank of division, leading to the name Magnoliophyta (from the family name Magnoliaceae). The Dahlgren system and Thorne system (1992) treat this group at the rank of class, leading to the name Magnoliopsida. The APG system of 1998, and the later 2003 and 2009 revisions, treat the flowering plants as a clade called angiosperms without a formal botanical name. However, a formal classification was published alongside the 2009 revision in which the flowering plants form the Subclass Magnoliidae.

Problem: Samurai:

Katō Kiyomasa was one of the most powerful and well-known lords of the Sengoku Era. He commanded most of Japan's major clans during the invasion of Korea (1592–1598). In a handbook he addressed to "all samurai, regardless of rank" he told his followers that a warrior's only duty in life was to "...grasp the long and the short swords and to die". He also ordered his followers to put forth great effort in studying the military classics, especially those related to loyalty and filial piety. He is best known for his quote: "If a man does not investigate into the matter of Bushido daily, it will be difficult for him to die a brave and manly death. Thus it is essential to engrave this business of the warrior into one's mind well."

What concept did Kato Kiyomasa think should be studied every day?
---
A: Bushido


Problem: Myanmar:

The Rohingya people have consistently faced human rights abuses by the Burmese regime that has refused to acknowledge them as Burmese citizens (despite some of them having lived in Burma for over three generations)—the Rohingya have been denied Burmese citizenship since the enactment of a 1982 citizenship law. The law created three categories of citizenship: citizenship, associate citizenship, and naturalised citizenship. Citizenship is given to those who belong to one of the national races such as Kachin, Kayah (Karenni), Karen, Chin, Burman, Mon, Rakhine, Shan, Kaman, or Zerbadee. Associate citizenship is given to those who cannot prove their ancestors settled in Myanmar before 1823, but can prove they have one grandparent, or pre-1823 ancestor, who was a citizen of another country, as well as people who applied for citizenship in 1948 and qualified then by those laws. Naturalized citizenship is only given to those who have at least one parent with one of these types of Burmese citizenship or can provide "conclusive evidence" that their parents entered and resided in Burma prior to independence in 1948. The Burmese regime has attempted to forcibly expel Rohingya and bring in non-Rohingyas to replace them—this policy has resulted in the expulsion of approximately half of the 800,000 Rohingya from Burma, while the Rohingya people have been described as "among the world's least wanted" and "one of the world's most persecuted minorities." But the origin of ‘most persecuted minority’ statement is unclear.

How does one become a full citizen in Burma ?

A: Citizenship is given to those who belong to one of the national races


Problem: Raleigh, North Carolina:

Raleigh is an early example in the United States of a planned city, chosen as the site of the state capital in 1788 and incorporated in 1792 as such. The city was originally laid out in a grid pattern with the North Carolina State Capitol in Union Square at the center. In the United States Civil War the city was spared from any significant battle, only falling in the closing days of the war, though it did not escape the economic hardships that plagued the rest of the American South during the Reconstruction Era. The twentieth century saw the opening of the Research Triangle Park in 1959, and with the jobs it created the region and city saw a large influx of population, making it one of the fastest growing communities in the United States by the early 21st century.

What century did Raleigh stop growing?
