Problem: Please answer a question about the following article about Separation of church and state in the United States:
Many early immigrant groups traveled to America to worship freely, particularly after the English Civil War and religious conflict in France and Germany. They included nonconformists like the Puritans, who were Protestant Christians fleeing religious persecution from the Anglican King of England. Despite a common background, the groups' views on religious toleration were mixed. While some such as Roger Williams of Rhode Island and William Penn of Pennsylvania ensured the protection of religious minorities within their colonies, others like the Plymouth Colony and Massachusetts Bay Colony had established churches. The Dutch colony of New Netherland established the Dutch Reformed Church and outlawed all other worship, though enforcement was sparse. Religious conformity was desired partly for financial reasons: the established Church was responsible for poverty relief, putting dissenting churches at a significant disadvantage.
What did William Penn ensure the protection of in his colony?
A: religious minorities
Problem: Please answer a question about the following article about Dwight D. Eisenhower:
In 1957, the state of Arkansas refused to honor a federal court order to integrate their public school system stemming from the Brown decision. Eisenhower demanded that Arkansas governor Orval Faubus obey the court order. When Faubus balked, the president placed the Arkansas National Guard under federal control and sent in the 101st Airborne Division. They escorted and protected nine black students' entry to Little Rock Central High School, an all-white public school, for the first time since the Reconstruction Era. Martin Luther King Jr. wrote to Eisenhower to thank him for his actions, writing "The overwhelming majority of southerners, Negro and white, stand firmly behind your resolute action to restore law and order in Little Rock".
How many black students were escorted by the 101st Airborne to Little Rock Central High School?
A: nine
Problem: Please answer a question about the following article about Bird migration:
The migration of birds also aids the movement of other species, including those of ectoparasites such as ticks and lice, which in turn may carry micro-organisms including those of concern to human health. Due to the global spread of avian influenza, bird migration has been studied as a possible mechanism of disease transmission, but it has been found not to present a special risk; import of pet and domestic birds is a greater threat. Some viruses that are maintained in birds without lethal effects, such as the West Nile Virus may however be spread by migrating birds. Birds may also have a role in the dispersal of propagules of plants and plankton.
What has a role in the dispersal of propagules of plants and plankton?
A: Birds
Problem: Please answer a question about the following article about History of science:
Muslim scientists placed far greater emphasis on experiment than had the Greeks. This led to an early scientific method being developed in the Muslim world, where significant progress in methodology was made, beginning with the experiments of Ibn al-Haytham (Alhazen) on optics from c. 1000, in his Book of Optics. The law of refraction of light was known to the Persians. The most important development of the scientific method was the use of experiments to distinguish between competing scientific theories set within a generally empirical orientation, which began among Muslim scientists. Ibn al-Haytham is also regarded as the father of optics, especially for his empirical proof of the intromission theory of light. Some have also described Ibn al-Haytham as the "first scientist" for his development of the modern scientific method.
What law did the Persians know of?
A:
The law of refraction of light
