Problem: Russian language:

In March 2013 it was announced that Russian is now the second-most used language on the Internet after English. People use the Russian language on 5.9% of all websites, slightly ahead of German and far behind English (54.7%). Russian is used not only on 89.8% of .ru sites, but also on 88.7% of sites with the former Soviet Union domain .su. The websites of former Soviet Union nations also use high levels of Russian: 79.0% in Ukraine, 86.9% in Belarus, 84.0% in Kazakhstan, 79.6% in Uzbekistan, 75.9% in Kyrgyzstan and 81.8% in Tajikistan. However, Russian is the sixth-most used language on the top 1,000 sites, behind English, Chinese, French, German and Japanese.

What percent of all websites are in Russian?

A: 5.9%

Problem: Dialect:

Modern standard Italian itself is heavily based on the Latin-derived Florentine Tuscan language. The Tuscan-based language that would eventually become modern standard Italian had been used in poetry and literature since at least the 12th century, and it first became widely known in Italy through the works of authors such as Dante Alighieri, Giovanni Boccaccio, Niccolo Machiavelli, and Petrarch. Dante's Florentine-Tuscan literary Italian thus became the language of the literate and upper class in Italy, and it spread throughout the peninsula as the lingua franca among the Italian educated class as well as Italian traveling merchants. The economic prowess and cultural and artistic importance of Tuscany in the Late Middle Ages and the Renaissance further encouraged the diffusion of the Florentine-Tuscan Italian throughout Italy and among the educated and powerful, though local and regional languages remained the main languages of the common people.

From what region of Italy did Florentine Tuscan derive?
---
A: Tuscany

Problem: Kathmandu:

Kathmandu has a larger proportion of tea drinkers than coffee drinkers. Tea is widely served but is extremely weak by western standards. It is richer and contains tea leaves boiled with milk, sugar and spices. Alcohol is widely drunk, and there are numerous local variants of alcoholic beverages. Drinking and driving is illegal, and authorities have a zero tolerance policy. Ailaa and thwon (alcohol made from rice) are the alcoholic beverages of Kathmandu, found in all the local bhattis (alcohol serving eateries). Chhyaang, tongba (fermented millet or barley) and rakshi are alcoholic beverages from other parts of Nepal which are found in Kathmandu. However, shops and bars in Kathmandu widely sell western and Nepali beers.

What goes through a fermentation process to create tongba?
---
A: millet or barley

Problem: Glass:

The term mainly refers to a mix of lithium and aluminosilicates that yields an array of materials with interesting thermomechanical properties. The most commercially important of these have the distinction of being impervious to thermal shock. Thus, glass-ceramics have become extremely useful for countertop cooking. The negative thermal expansion coefficient (CTE) of the crystalline ceramic phase can be balanced with the positive CTE of the glassy phase. At a certain point (~70% crystalline) the glass-ceramic has a net CTE near zero. This type of glass-ceramic exhibits excellent mechanical properties and can sustain repeated and quick temperature changes up to 1000 C.

What proportion of crystalline ceramics yields a product with a CTE of around 0?
---
A:
~70%
