Question: There are over three thousand islands along the rugged coastline of Zhejiang. The largest, Zhoushan Island, is Mainland China's third largest island, after Hainan and Chongming. There are also many bays, of which Hangzhou Bay is the largest. Zhejiang has a humid subtropical climate with four distinct seasons. Spring starts in March and is rainy with changeable weather. Summer, from June to September is long, hot, rainy, and humid. Fall is generally dry, warm and sunny. Winters are short but cold except in the far south. Average annual temperature is around 15 to 19 C (59 to 66 F), average January temperature is around 2 to 8 C (36 to 46 F) and average July temperature is around 27 to 30 C (81 to 86 F). Annual precipitation is about 1,000 to 1,900 mm (39 to 75 in). There is plenty of rainfall in early summer, and by late summer Zhejiang is directly threatened by typhoons forming in the Pacific.

Question: Victoria's youngest son, Leopold, was affected by the blood-clotting disease haemophilia B and two of her five daughters, Alice and Beatrice, were carriers. Royal haemophiliacs descended from Victoria included her great-grandsons, Tsarevich Alexei of Russia, Alfonso, Prince of Asturias, and Infante Gonzalo of Spain. The presence of the disease in Victoria's descendants, but not in her ancestors, led to modern speculation that her true father was not the Duke of Kent but a haemophiliac. There is no documentary evidence of a haemophiliac in connection with Victoria's mother, and as male carriers always suffer the disease, even if such a man had existed he would have been seriously ill. It is more likely that the mutation arose spontaneously because Victoria's father was over 50 at the time of her conception and haemophilia arises more frequently in the children of older fathers. Spontaneous mutations account for about a third of cases.
Is there an answer to this question: In how many births do spontaneous cases of haemophilia arise?

Answer: about a third of cases

Question: The economy of Russia became heavily industrialized, accounting for about two-thirds of the electricity produced in the USSR. It was, by 1961, the third largest producer of petroleum due to new discoveries in the Volga-Urals region and Siberia, trailing only the United States and Saudi Arabia. In 1974, there were 475 institutes of higher education in the republic providing education in 47 languages to some 23,941,000 students. A network of territorially-organized public-health services provided health care. After 1985, the restructuring policies of the Gorbachev administration relatively liberalised the economy, which had become stagnant since the late 1970s, with the introduction of non-state owned enterprises such as cooperatives. The effects of market policies led to the failure of many enterprises and total instability by 1990.
Is there an answer to this question: What two countries produced less petroleum than Russia in 1961?

Answer:
unanswerable
