The problem: Answer a question about this article:
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.
Where does the highest rainfall occur in Namibia?
****
The answer: Caprivi

During the second half of the 19th century the bourgeoisie encouraged the development of the city and its environs; land-owners were enriched by the introduction of the orange crop and the expansion of vineyards and other crops,. This economic boom corresponded with a revival of local traditions and of the Valencian language, which had been ruthlessly suppressed from the time of Philip V. Around 1870, the Valencian Renaissance, a movement committed to the revival of the Valencian language and traditions, began to gain ascendancy. In its early stages the movement inclined to the romanticism of the poet Teodor Llorente, and resisted the more assertive remonstrances of Constantine Llombart, founder of the still extant cultural society, Lo Rat Penat, which is dedicated to the promotion and dissemination of the Valencian language and culture.
What group still exists and promotes Valencian culture?
****
The answer: Lo Rat Penat

Research has generally shown striking uniformity across different cultures in the motives behind teen alcohol use. Social engagement and personal enjoyment appear to play a fairly universal role in adolescents' decision to drink throughout separate cultural contexts. Surveys conducted in Argentina, Hong Kong, and Canada have each indicated the most common reason for drinking among adolescents to relate to pleasure and recreation; 80% of Argentinian teens reported drinking for enjoyment, while only 7% drank to improve a bad mood. The most prevalent answers among Canadian adolescents were to "get in a party mood," 18%; "because I enjoy it," 16%; and "to get drunk," 10%. In Hong Kong, female participants most frequently reported drinking for social enjoyment, while males most frequently reported drinking to feel the effects of alcohol.
What percentage of Argentenian teens reported drinking to improve a bad mood?
****
The answer: 7%


The problem: Answer a question about this article:
In the 20th century, as Beijing, Shanghai, Nanjing, and Wuhan had all been occupied by the Japanese during the Second Sino-Japanese War, the capital of the Republic of China had been temporary relocated to Chongqing, then a major city in Sichuan. An enduring legacy of this move is that nearby inland provinces, such as Shaanxi, Gansu, and Guizhou, which previously never had modern Western-style universities, began to be developed in this regard. The difficulty of accessing the region overland from the eastern part of China and the foggy climate hindering the accuracy of Japanese bombing of the Sichuan Basin, made the region the stronghold of Chiang Kai-Shek's Kuomintang government during 1938-45, and led to the Bombing of Chongqing.
What are some major cities occupied by the Chinese during the Second Sino-Japanese War?
****
The answer:
Beijing, Shanghai, Nanjing, and Wuhan
