Problem: Dutch Republic:

The Dutch Republic, also known as the Republic of the Seven United Netherlands (Republiek der Zeven Verenigde Nederlanden), Republic of the United Netherlands or Republic of the Seven United Provinces (Republiek der Zeven Verenigde Provinciën), was a republic in Europe existing from 1581, when part of the Netherlands separated from Spanish rule, until 1795. It preceded the Batavian Republic, the Kingdom of Holland, the United Kingdom of the Netherlands, and ultimately the modern Kingdom of the Netherlands. Alternative names include the United Provinces (Verenigde Provinciën), Federated Dutch Provinces (Foederatae Belgii Provinciae), and Dutch Federation (Belgica Foederata).

Problem: Russian language:

Russian is one of the official languages (or has similar status and interpretation must be provided into Russian) of the United Nations, International Atomic Energy Agency, World Health Organization, International Civil Aviation Organization, UNESCO, World Intellectual Property Organization, International Telecommunication Union, World Meteorological Organization, Food and Agriculture Organization, International Fund for Agricultural Development, International Criminal Court, International Monetary Fund, International Olympic Committee, Universal Postal Union, World Bank, Commonwealth of Independent States, Organization for Security and Co-operation in Europe, Shanghai Cooperation Organisation, Eurasian Economic Community, Collective Security Treaty Organization, Antarctic Treaty Secretariat, International Organization for Standardization, GUAM Organization for Democracy and Economic Development, International Mathematical Olympiad. The Russian language is also one of two official languages aboard the International Space Station - NASA astronauts who serve alongside Russian cosmonauts usually take Russian language courses. This practice goes back to the Apollo-Soyuz mission, which first flew in 1975.

Problem: Qing dynasty:

In the wake of these external defeats, the Guangxu Emperor initiated the Hundred Days' Reform of 1898. Newer, more radical advisers such as Kang Youwei were given positions of influence. The emperor issued a series of edicts and plans were made to reorganize the bureaucracy, restructure the school system, and appoint new officials. Opposition from the bureaucracy was immediate and intense. Although she had been involved in the initial reforms, the empress dowager stepped in to call them off, arrested and executed several reformers, and took over day-to-day control of policy. Yet many of the plans stayed in place, and the goals of reform were implanted.

Name an advisor to Guangxu?

A: Kang Youwei


Problem: Hydrogen:

The electrolysis of water is a simple method of producing hydrogen. A low voltage current is run through the water, and gaseous oxygen forms at the anode while gaseous hydrogen forms at the cathode. Typically the cathode is made from platinum or another inert metal when producing hydrogen for storage. If, however, the gas is to be burnt on site, oxygen is desirable to assist the combustion, and so both electrodes would be made from inert metals. (Iron, for instance, would oxidize, and thus decrease the amount of oxygen given off.) The theoretical maximum efficiency (electricity used vs. energetic value of hydrogen produced) is in the range 80–94%.

Where does the gaseous hydrogen form at?

A:
cathode
