Here is a question about this article: Dark meat, which avian myologists refer to as "red muscle", is used for sustained activitychiefly walking, in the case of a chicken. The dark colour comes from the protein myoglobin, which plays a key role in oxygen uptake and storage within cells. White muscle, in contrast, is suitable only for short bursts of activity such as, for chickens, flying. Thus, the chicken's leg and thigh meat are dark, while its breast meat (which makes up the primary flight muscles) is white. Other birds with breast muscle more suitable for sustained flight, such as ducks and geese, have red muscle (and therefore dark meat) throughout. Some cuts of meat including poultry expose the microscopic regular structure of intracellular muscle fibrils which can diffract light and produce iridescent colours, an optical phenomenon sometimes called structural colouration.
What is the answer to this question: What causes the meat of some poultry to show rainbow like colr striations?
****
So... the microscopic regular structure of intracellular muscle fibrils which can diffract light and produce iridescent colours

The problem: Answer a question about this article:
After the death of the replacement bishop Gregory in 345, Constans used his influence to allow Athanasius to return to Alexandria in October 345, amidst the enthusiastic demonstrations of the populace. This began a "golden decade" of peace and prosperity, during which time Athanasius assembled several documents relating to his exiles and returns from exile in the Apology Against the Arians. However, upon Constans's death in 350, another civil war broke out, which left pro-Arian Constantius as sole emperor. An Alexandria local council in 350 replaced (or reaffirmed) Athanasius in his see.
Did the new emperor agree or disagree with the Arians?
****
The answer: pro-Arian

Problem: Please answer a question about the following article about Jehovah%27s Witnesses:
Jehovah's Witnesses is a millenarian restorationist Christian denomination with nontrinitarian beliefs distinct from mainstream Christianity. The group claims a worldwide membership of more than 8.2 million adherents involved in evangelism, convention attendance figures of more than 15 million, and an annual Memorial attendance of more than 19.9 million. Jehovah's Witnesses are directed by the Governing Body of Jehovah's Witnesses, a group of elders in Brooklyn, New York, which establishes all doctrines based on its interpretations of the Bible.

They believe that the destruction of the present world system at Armageddon is imminent, and that the establishment of God's kingdom over the earth is the only solution for all problems faced by humanity.
What are the beliefs of Jehovah Witnesses distinct from?
A: mainstream Christianity

Question: Read this and answer the question

Whitehead makes the startling observation that "life is comparatively deficient in survival value." If humans can only exist for about a hundred years, and rocks for eight hundred million, then one is forced to ask why complex organisms ever evolved in the first place; as Whitehead humorously notes, "they certainly did not appear because they were better at that game than the rocks around them." He then observes that the mark of higher forms of life is that they are actively engaged in modifying their environment, an activity which he theorizes is directed toward the three-fold goal of living, living well, and living better. In other words, Whitehead sees life as directed toward the purpose of increasing its own satisfaction. Without such a goal, he sees the rise of life as totally unintelligible.

Without Whitehead's proposed purpose, life would be what?
Answer: unintelligible

Problem: When Emperor Haile Selassie unilaterally dissolved the Eritrean parliament and annexed the country in 1962, the Eritrean Liberation Front (ELF) waged an armed struggle for independence. The ensuing Eritrean War for Independence went on for 30 years against successive Ethiopian governments until 1991, when the Eritrean People's Liberation Front (EPLF), a successor of the ELF, defeated the Ethiopian forces in Eritrea and helped a coalition of Ethiopian rebel forces take control of the Ethiopian Capital Addis Ababa.
What does the acroynm ELF stand for?
The answer is the following: Eritrean Liberation Front

Input: Article: In the Prussian province of Posen, with a large Polish population, there was strong support for the French and angry demonstrations at news of Prussian-German victoriesa clear manifestation of Polish nationalist feeling. Calls were also made for Polish recruits to desert from the Prussian Armythough these went mainly unheeded. An alarming report on the Posen situation, sent to Bismarck on 16 August 1870, led to the quartering of reserve troop contingents in the restive province. The Franco-Prussian War thus turned out to be a significant event also in GermanPolish relations, marking the beginning of a prolonged period of repressive measures by the authorities and efforts at Germanisation.

Now answer this question: On what date did Bismarkck receive the disturbing report on the Posen situation?

Output:
16 August 1870
