Problem: Sahara:

The Sahara (Arabic: , as-sahra al-kubra, 'the Greatest Desert') is the largest hot desert in the world. It is the third largest desert after Antarctica and the Arctic. Its surface area of 9,400,000 square kilometres (3,600,000 sq mi)[citation needed]including the Libyan Desertis comparable to the respective land areas of China or the United States. The desert comprises much of the land found within North Africa, excluding the fertile coastal region situated against the Mediterranean Sea, the Atlas Mountains of the Maghreb, and the Nile Valley of Egypt and Sudan. The Sahara stretches from the Red Sea in the east and the Mediterranean in the north, to the Atlantic Ocean in the west, where the landscape gradually transitions to a coastal plain. To the south, it is delimited by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and Sudan Region of Sub-Saharan Africa. The Sahara can be divided into several regions, including the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Air Mountains, the Tenere desert, and the Libyan Desert. Its name is derived from the plural Arabic language word for desert ( sahara [sr]).

Problem: Copyright infringement:

Some copyright owners voluntarily reduce the scope of what is considered infringement by employing relatively permissive, "open" licensing strategies: rather than privately negotiating license terms with individual users who must first seek out the copyright owner and ask for permission, the copyright owner publishes and distributes the work with a prepared license that anyone can use, as long as they adhere to certain conditions. This has the effect of reducing infringement and the burden on courts by simply permitting certain types of uses under terms that the copyright owner considers reasonable. Examples include free software licenses, like the GNU General Public License (GPL), and the Creative Commons licenses, which are predominantly applied to visual and literary works.

What do some copyright owners do by reducing the scope of infringement?

A: employing relatively permissive, "open" licensing

Problem: Federalism:

On one hand, this means that the Belgian political landscape, generally speaking, consists of only two components: the Dutch-speaking population represented by Dutch-language political parties, and the majority populations of Wallonia and Brussels, represented by their French-speaking parties. The Brussels region emerges as a third component. This specific dual form of federalism, with the special position of Brussels, consequently has a number of political issueseven minor onesthat are being fought out over the Dutch/French-language political division. With such issues, a final decision is possible only in the form of a compromise. This tendency gives this dual federalism model a number of traits that generally are ascribed to confederalism, and makes the future of Belgian federalism contentious.

What component is the Brussel Region?
---
A: third component

Problem: Alaska:

Alaska's internet and other data transport systems are provided largely through the two major telecommunications companies: GCI and Alaska Communications. GCI owns and operates what it calls the Alaska United Fiber Optic system and as of late 2011 Alaska Communications advertised that it has "two fiber optic paths to the lower 48 and two more across Alaska. In January 2011, it was reported that a $1 billion project to run connect Asia and rural Alaska was being planned, aided in part by $350 million in stimulus from the federal government.

In what year was a project to connect Russia and rural Alaska announced?
