Problem: Namibia:

Namibia is the driest country in sub-Saharan Africa and depends largely on groundwater. With an average rainfall of about 350 mm per annum, the highest rainfall occurs in the Caprivi in the northeast (about 600 mm per annum) and decreases in a westerly and southwesterly direction to as little as 50 mm and less per annum at the coast. The only perennial rivers are found on the national borders with South Africa, Angola, Zambia, and the short border with Botswana in the Caprivi. In the interior of the country surface water is available only in the summer months when rivers are in flood after exceptional rainfalls. Otherwise, surface water is restricted to a few large storage dams retaining and damming up these seasonal floods and their runoff. Thus, where people don’t live near perennial rivers or make use of the storage dams, they are dependent on groundwater. The advantage of using groundwater sources is that even isolated communities and those economic activities located far from good surface water sources such as mining, agriculture, and tourism can be supplied from groundwater over nearly 80% of the country.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Song dynasty reëstablished unity around 960. Under the Song, the prosperity of South China began to overtake that of North China. After the north was lost to the Jurchen Jin dynasty in 1127 following the Jingkang Incident, Hangzhou became the capital of the Southern Song under the name Lin'an. Renowned for its prosperity and beauty, it may have been the largest city in the world at the time. From then on, north Zhejiang and neighboring south Jiangsu have been synonymous with luxury and opulence in Chinese culture. The Mongol conquest and the establishment of the Yuan dynasty in 1279 ended Hangzhou's political clout, but its economy continued to prosper. Marco Polo visited the city, which he called "Kinsay" (after the Chinese Jingshi, meaning "Capital City") claiming it was "the finest and noblest city in the world".
What happened in 1126?
A: unanswerable


Context and question: Historical aspects of the Expo line route are noteworthy. It uses the right-of-way for the Santa Monica Air Line that provided electric-powered freight and passenger service between Los Angeles and Santa Monica beginning in the 1920s. Service was discontinued in 1953 but diesel-powered freight deliveries to warehouses along the route continued until March 11, 1988. The abandonment of the line spurred concerns within the community and the entire right-of-way was purchased from Southern Pacific by Los Angeles Metropolitan Transportation Authority. The line was built in 1875 as the steam-powered Los Angeles and Independence Railroad to bring mining ore to ships in Santa Monica harbor and as a passenger excursion train to the beach.
In what year were electric-powered freight trains invented?
Answer: unanswerable

QUES: Comprehensive schools have been accused of grade inflation after a study revealed that Gymnasium senior students of average mathematical ability found themselves at the very bottom of their class and had an average grade of "Five", which means "Failed". Gesamtschule senior students of average mathematical ability found themselves in the upper half of their class and had an average grade of "Three Plus". When a central Abitur examination was established in the State of North Rhine-Westphalia, it was revealed that Gesamtschule students did worse than could be predicted by their grades or class rank. Barbara Sommer (Christian Democratic Union), Education Minister of North Rhine-Westphalia, commented that: Looking at the performance gap between comprehensives and the Gymnasium [at the Abitur central examination] [...] it is difficult to understand why the Social Democratic Party of Germany wants to do away with the Gymnasium. [...] The comprehensives do not help students achieve [...] I am sick and tired of the comprehensive schools blaming their problems on the social class origins of their students. What kind of attitude is this to blame their own students? She also called the Abitur awarded by the Gymnasium the true Abitur and the Abitur awarded by the Gesamtschule "Abitur light". As a reaction, Sigrid Beer (Alliance '90/The Greens) stated that comprehensives were structurally discriminated against by the government, which favoured the Gymnasiums. She also said that many of the students awarded the Abitur by the comprehensives came from "underprivileged groups" and sneering at their performance was a "piece of impudence".
