Ter-Petrosyan led Armenia alongside Defense Minister Vazgen Sargsyan through the Nagorno-Karabakh War with neighboring Azerbaijan. The initial post-Soviet years were marred by economic difficulties, which had their roots early in the Karabakh conflict when the Azerbaijani Popular Front managed to pressure the Azerbaijan SSR to instigate a railway and air blockade against Armenia. This move effectively crippled Armenia's economy as 85% of its cargo and goods arrived through rail traffic. In 1993, Turkey joined the blockade against Armenia in support of Azerbaijan.
What percent of Armenias commodities were transported via rail traffic?
85%


Input: Zhejiang
Zhejiang benefited less from central government investment than some other provinces due to its lack of natural resources, a location vulnerable to potential flooding from the sea, and an economic base at the national average. Zhejiang, however, has been an epicenter of capitalist development in China, and has led the nation in the development of a market economy and private enterprises. Northeast Zhejiang, as part of the Yangtze Delta, is flat, more developed, and industrial.

Which part of Zhejiang is part of the Yangtze Delta?
Output: Northeast Zhejiang


Input: Article: Nasser appointed himself the additional roles of prime minister and supreme commander of the armed forces on 19 June 1967. Angry at the military court's perceived leniency with air force officers charged with negligence during the 1967 war, workers and students launched protests calling for major political reforms in late February 1968. Nasser responded to the demonstrations, the most significant public challenge to his rule since workers' protests in March 1954, by removing most military figures from his cabinet and appointing eight civilians in place of several high-ranking members of the Arab Socialist Union (ASU). By 3 March, Nasser directed Egypt's intelligence apparatus to focus on external rather than domestic espionage, and declared the "fall of the mukhabarat state".

Now answer this question: What type of spying did Nasser want to concentrate on?

Output: external


Article: The first attempts to use standard-frequency single-phase AC were made in Hungary as far back as 1923, by the Hungarian Kálmán Kandó on the line between Budapest-Nyugati and Alag, using 16 kV at 50 Hz. The locomotives carried a four-pole rotating phase converter feeding a single traction motor of the polyphase induction type at 600 to 1,100 V. The number of poles on the 2,500 hp motor could be changed using slip rings to run at one of four synchronous speeds. The tests were a success so, from 1932 until the 1960s, trains on the Budapest-Hegyeshalom line (towards Vienna) regularly used the same system. A few decades after the Second World War, the 16 kV was changed to the Russian and later French 25 kV system.

Question: How could the locomotives run on four speed levels?
Ans: motor could be changed using slip rings


Here is a question about this article: Mainstream AC itself has evolved in a similar fashion over the years; traditional AC artists like Barbra Streisand, the Carpenters, Dionne Warwick, Barry Manilow, John Denver, and Olivia Newton-John found it harder to have major Top 40 hits as the 1980s wore on, and due to the influence of MTV, artists who were staples of the Contemporary Hit Radio format, such as Richard Marx, Michael Jackson, Bonnie Tyler, George Michael, Phil Collins, and Laura Branigan began crossing over to the AC charts with greater frequency. Collins has been described by AllMusic as "one of the most successful pop and adult contemporary singers of the '80s and beyond". However, with the combination of MTV and AC radio, adult contemporary appeared harder to define as a genre, with established soft-rock artists of the past still charting pop hits and receiving airplay alongside mainstream radio fare from newer artists at the time.
What is the answer to this question: Who did Allmusic refer to as "one of the most successful pop and adult contemporary singers of the '80s and beyond"?
****
So... Phil Collins


Article: Historical studies reveal that policing agents have undertaken a variety of cross-border police missions for many years (Deflem, 2002). For example, in the 19th century a number of European policing agencies undertook cross-border surveillance because of concerns about anarchist agitators and other political radicals. A notable example of this was the occasional surveillance by Prussian police of Karl Marx during the years he remained resident in London. The interests of public police agencies in cross-border co-operation in the control of political radicalism and ordinary law crime were primarily initiated in Europe, which eventually led to the establishment of Interpol before the Second World War. There are also many interesting examples of cross-border policing under private auspices and by municipal police forces that date back to the 19th century (Nadelmann, 1993). It has been established that modern policing has transgressed national boundaries from time to time almost from its inception. It is also generally agreed that in the post–Cold War era this type of practice became more significant and frequent (Sheptycki, 2000).

Question: In what era did cross-border policing increase?
Ans:
post–Cold War
