A struggle for succession in the mid-twelfth century gave the Fujiwara an opportunity to regain their former power. Fujiwara no Yorinaga sided with the retired emperor in a violent battle in 1156 against the heir apparent, who was supported by the Taira and Minamoto (Hōgen Rebellion). In the end, the Fujiwara were destroyed, the old system of government supplanted, and the insei system left powerless as bushi took control of court affairs, marking a turning point in Japanese history. In 1159, the Taira and Minamoto clashed (Heiji Rebellion), and a twenty-year period of Taira ascendancy began.

After the Heiji Rebellion, what clan grew in power?

In Epperson v. Arkansas, 393 U.S. 97 (1968), the Supreme Court considered an Arkansas law that made it a crime "to teach the theory or doctrine that mankind ascended or descended from a lower order of animals," or "to adopt or use in any such institution a textbook that teaches" this theory in any school or university that received public funds. The court's opinion, written by Justice Abe Fortas, ruled that the Arkansas law violated "the constitutional prohibition of state laws respecting an establishment of religion or prohibiting the free exercise thereof. The overriding fact is that Arkansas' law selects from the body of knowledge a particular segment which it proscribes for the sole reason that it is deemed to conflict with a particular religious doctrine; that is, with a particular interpretation of the Book of Genesis by a particular religious group." The court held that the Establishment Clause prohibits the state from advancing any religion, and that "[T]he state has no legitimate interest in protecting any or all religions from views distasteful to them." 

Who wrote the court's opinion in Epperson v. Arkansas?
Answer: Justice Abe Fortas

The administration continues to follow the market reform plans of the previous one and indicated that it will diversify Iran's oil-reliant economy. Iran has also developed a biotechnology, nanotechnology, and pharmaceuticals industry. However, nationalized industries such as the bonyads have often been managed badly, making them ineffective and uncompetitive with years. Currently, the government is trying to privatize these industries, and, despite successes, there are still several problems to be overcome, such as the lagging corruption in the public sector and lack of competitiveness. In 2010, Iran was ranked 69, out of 139 nations, in the Global Competitiveness Report.

What, along with a lack of competition, has held back Iran's nationalized industries?
Answer:
lagging corruption in the public sector
