Problem: Palermo:

The Muslims took control of the Island in 904, after decades of fierce fighting, and the Emirate of Sicily was established. Muslim rule on the island lasted for about 120 years and was marked by cruelty and brutality against the native population, which was reduced into near slavery[clarification needed] and Christian churches across the island were all completely destroyed.[page needed] Palermo (Balarm during Arab rule) displaced Syracuse as the capital city of Sicily. It was said to have then begun to compete with Cordoba and Cairo in terms of importance and splendor. For more than one hundred years Palermo was the capital of a flourishing emirate. The Arabs also introduced many agricultural crops which remain a mainstay of Sicilian cuisine.

How were the indigenous Palermo population treated under Muslim rule?

A: reduced into near slavery

Problem: In 2010 and 2011, state and federal funds were awarded to Connecticut (and Massachusetts) to construct the Hartford Line, with a southern terminus at New Haven's Union Station and a northern terminus at Springfield's Union Station. According to the White House, "This corridor [currently] has one train per day connecting communities in Connecticut and Massachusetts to the Northeast Corridor and Vermont. The vision for this corridor is to restore the alignment to its original route via the Knowledge Corridor in western Massachusetts, improving trip time and increasing the population base that can be served." Set for construction in 2013, the "Knowledge Corridor high speed intercity passenger rail" project will cost approximately $1 billion, and the ultimate northern terminus for the project is reported to be Montreal in Canada. Train speeds between will reportedly exceed 110 miles per hour (180 km/h) and increase both cities' rail traffic exponentially.
Where is the starting point of the terminus line in New Haven?

Answer: New Haven's Union Station

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Building first evolved out of the dynamics between needs (shelter, security, worship, etc.) and means (available building materials and attendant skills). As human cultures developed and knowledge began to be formalized through oral traditions and practices, building became a craft, and "architecture" is the name given to the most highly formalized and respected versions of that craft.
What dynamic needs were the reason for building to be done?
A: shelter, security, worship

Context and question: Birds have a very efficient system for diffusing oxygen into the blood; birds have a ten times greater surface area to gas exchange volume than mammals. As a result, birds have more blood in their capillaries per unit of volume of lung than a mammal. The arteries are composed of thick elastic muscles to withstand the pressure of the ventricular constriction, and become more rigid as they move away from the heart. Blood moves through the arteries, which undergo vasoconstriction, and into arterioles which act as a transportation system to distribute primarily oxygen as well as nutrients to all tissues of the body. As the arterioles move away from the heart and into individual organs and tissues they are further divided to increase surface area and slow blood flow. Travelling through the arterioles blood moves into the capillaries where gas exchange can occur. Capillaries are organized into capillary beds in tissues, it is here that blood exchanges oxygen for carbon dioxide waste. In the capillary beds blood flow is slowed to allow maximum diffusion of oxygen into the tissues. Once the blood has become deoxygenated it travels through venules then veins and back to the heart. Veins, unlike arteries, are thin and rigid as they do not need to withstand extreme pressure. As blood travels through the venules to the veins a funneling occurs called vasodilation bringing blood back to the heart. Once the blood reaches the heart it moves first into the right atrium, then the right ventricle to be pumped through the lungs for further gas exchange of carbon dioxide waste for oxygen. Oxygenated blood then flows from the lungs through the left atrium to the left ventricle where it is pumped out to the body.
What is organized into capillary beds in tissues?
Answer: Capillaries

Question: The term Hokkien (; hkkn) is itself a term not used in Chinese to refer to the dialect, as it simply means Fujian province. In Chinese linguistics, these dialects are known by their classification under the Quanzhang Division (Chinese: ; pinyin: Quanzhang pian) of Min Nan, which comes from the first characters of the two main Hokkien urban centers Quanzhou and Zhangzhou. The variety is also known by other terms such as the more general Min Nan (traditional Chinese: , ; simplified Chinese: , ; pinyin: Minnanyu, Minnanhua; Peh-oe-ji: Ban-lam-gi,Ban-lam-oe) or Southern Min, and Fulaohua (traditional Chinese: ; simplified Chinese: ; pinyin: Fulaohua; Peh-oe-ji: Ho-lo-oe). The term Hokkien (Chinese: ; Peh-oe-ji: hok-kian oe;Tai-lo:Hok-kian-ue), on the other hand, is used commonly in South East Asia to refer to Min-nan dialects.
Is there an answer to this question: What division of dialects does Hokkien belong to?

Answer: Quanzhang Division (Chinese: ; pinyin: Quanzhang pian) of Min Nan

Problem: 2008 Summer Olympics torch relay:

Internationally, the torch and its accompanying party traveled in a chartered Air China Airbus A330 (registered B-6075), painted in the red and yellow colors of the Olympic Games. Air China was chosen by the Beijing Committees of the Olympic Game as the designated Olympic torch carrier in March 2008 for its long-standing participation in the Olympic cause. The plane traveled a total of 137,000 km (85,000 mi) for a duration of 130 days through 21 countries and regions.

How many days did the plane travel?
---
A:
130 days
