Since regaining independence, Estonia has pursued a foreign policy of close co-operation with its Western European partners. The two most important policy objectives in this regard have been accession into NATO and the European Union, achieved in March and May 2004 respectively. Estonia's international realignment toward the West has been accompanied by a general deterioration in relations with Russia, most recently demonstrated by the protest triggered by the controversial relocation of the Bronze Soldier World War II memorial in Tallinn.

What type of foreign policy has Estonia sought after getting their independence?
Answer: close co-operation

Problem: Disadvantages of electric traction include high capital costs that may be uneconomic on lightly trafficked routes; a relative lack of flexibility since electric trains need electrified tracks or onboard supercapacitors and charging infrastructure at stations; and a vulnerability to power interruptions. Different regions may use different supply voltages and frequencies, complicating through service. The limited clearances available under catenaries may preclude efficient double-stack container service. The lethal voltages on contact wires and third rails are a safety hazard to track workers, passengers and trespassers. Overhead wires are safer than third rails, but they are often considered unsightly.
Why overhead wires are not being widely used?
The answer is the following: considered unsightly.

Animal tissue consists of elements and compounds ingested, digested, absorbed, and circulated through the bloodstream to feed the cells of the body. Except in the unborn fetus, the digestive system is the first system involved[vague]. Digestive juices break chemical bonds in ingested molecules, and modify their conformations and energy states. Though some molecules are absorbed into the bloodstream unchanged, digestive processes release them from the matrix of foods. Unabsorbed matter, along with some waste products of metabolism, is eliminated from the body in the feces.
What is able to break bonds in ingested molecules?
Digestive juices

Textiles from all over the world can be visited in the Museum for textile art. The EXPOseeum is the museum of the world-exhibition "EXPO 2000 Hannover". Carpets and objects from the orient can be visited in the Oriental Carpet Museum. The Blind Man Museum is a rarity in Germany, another one is only in Berlin. The Museum of veterinary medicine is unique in Germany. The Museum for Energy History describes the 150 years old history of the application of energy. The Home Museum Ahlem shows the history of the district of Ahlem. The Mahn- und Gedenkstatte Ahlem describes the history of the Jewish people in Hanover and the Stiftung Ahlers Pro Arte / Kestner Pro Arte shows modern art. Modern art is also the main topic of the Kunsthalle Faust, the Nord/LB Art Gellery and of the Foro Artistico / Eisfabrik.

Where can you find carpets and objects from the orient?
Output: Oriental Carpet Museum

Input: Article: Smith's first Macintosh board was built to Raskin's design specifications: it had 64 kilobytes (kB) of RAM, used the Motorola 6809E microprocessor, and was capable of supporting a 256256-pixel black-and-white bitmap display. Bud Tribble, a member of the Mac team, was interested in running the Apple Lisa's graphical programs on the Macintosh, and asked Smith whether he could incorporate the Lisa's Motorola 68000 microprocessor into the Mac while still keeping the production cost down. By December 1980, Smith had succeeded in designing a board that not only used the 68000, but increased its speed from 5 MHz to 8 MHz; this board also had the capacity to support a 384256-pixel display. Smith's design used fewer RAM chips than the Lisa, which made production of the board significantly more cost-efficient. The final Mac design was self-contained and had the complete QuickDraw picture language and interpreter in 64 kB of ROM far more than most other computers; it had 128 kB of RAM, in the form of sixteen 64 kilobit (kb) RAM chips soldered to the logicboard. Though there were no memory slots, its RAM was expandable to 512 kB by means of soldering sixteen IC sockets to accept 256 kb RAM chips in place of the factory-installed chips. The final product's screen was a 9-inch, 512x342 pixel monochrome display, exceeding the size of the planned screen.

Now answer this question: Which design feature did Smith eventually use to make production of a newly designed board more cost-efficient?

Output: fewer RAM chips than the Lisa

Problem: Even during the war, Eritrea developed its transportation infrastructure by asphalting new roads, improving its ports, and repairing war-damaged roads and bridges as a part of the Warsay Yika'alo Program. The most significant of these projects was the construction of a coastal highway of more than 500 km connecting Massawa with Asseb, as well as the rehabilitation of the Eritrean Railway. The rail line has been restored between the port of Massawa and the capital Asmara, although services are sporadic. Steam locomotives are sometimes used for groups of enthusiasts.
How long was the coastal highway between Massawa and Asseb?
The answer is the following:
more than 500 km
