Problem: Queen Victoria:

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.

What is the sex of carriers that always suffer the blood clotting disease haemophi;ia B?
---
A: male


Problem: On 27 June 1950, two days after the KPA invaded and three months before the Chinese entered the war, President Truman dispatched the United States Seventh Fleet to the Taiwan Strait, to prevent hostilities between the Nationalist Republic of China (Taiwan) and the People's Republic of China (PRC). On 4 August 1950, with the PRC invasion of Taiwan aborted, Mao Zedong reported to the Politburo that he would intervene in Korea when the People's Liberation Army's (PLA) Taiwan invasion force was reorganized into the PLA North East Frontier Force. China justified its entry into the war as a response to "American aggression in the guise of the UN".
What year did China decide to enter the war?

Answer: 1950


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Government revenues largely come from sales of fishing licenses, income from the Tuvalu Trust Fund, and from the lease of its highly fortuitous .tv Internet Top Level Domain (TLD). In 1998, Tuvalu began deriving revenue from the use of its area code for premium-rate telephone numbers and from the commercialisation of its ".tv" Internet domain name, which is now managed by Verisign until 2021. The ".tv" domain name generates around $2.2 million each year from royalties, which is about ten per cent of the government's total revenue. Domain name income paid most of the cost of paving the streets of Funafuti and installing street lighting in mid-2002. Tuvalu also generates income from stamps by the Tuvalu Philatelic Bureau and income from the Tuvalu Ship Registry.
How much money does Tuvalu's tv domain name earn each year?
A: $2.2 million


Context and question: Series of lower mountain ranges run parallel to the main chain of the Alps, including the French Prealps in France and the Jura Mountains in Switzerland and France. The secondary chain of the Alps follows the watershed from the Mediterranean Sea to the Wienerwald, passing over many of the highest and most well-known peaks in the Alps. From the Colle di Cadibona to Col de Tende it runs westwards, before turning to the northwest and then, near the Colle della Maddalena, to the north. Upon reaching the Swiss border, the line of the main chain heads approximately east-northeast, a heading it follows until its end near Vienna.
Where are the French Prealps located? 
Answer: France

Question: The officials in Mexico City reduced the price of corn from six cents to two cents a pound. The northern portion of the state continued to decline economically which led to another revolt led by G. Casavantes in August 1879; Governor Trías was accused of misappropriation of funds and inefficient administration of the state. Casavantes took the state capital and occupied it briefly; he was also successful in forcing Governor Trías to exile. Shortly afterwards, the federal government sent an entourage led by Treviño; Casavantes was immediately ordered to resign his position. Casavantes declared political victory as he was able to publicly accuse and depose Governor Trías. At the same time the states of Durango and Coahuila had a military confrontation over territorial claims and water rights; this altercation between the state required additional federal troops to stabilize the area. Later a dispute ensued again among the states of Coahuila, Durango, and Chihuahua over the mountain range area known as Sierra Mojada, when large deposits of gold ore was discovered. The state of Chihuahua officially submitted a declaration of protest in May 1880 that shortly after was amicably settled. Despite the difficulties at the beginning, Díaz was able to secure and stabilize the state, which earned the confidence and support of the people.
Is there an answer to this question: Who was able to secure and stabilize the state eventually and gain the support of the people?

Answer:
Díaz
