In the 1950s, the Ethiopian feudal administration under Emperor Haile Selassie sought to annex Eritrea and Italian Somaliland. He laid claim to both territories in a letter to Franklin D. Roosevelt at the Paris Peace Conference and at the First Session of the United Nations. In the United Nations, the debate over the fate of the former Italian colonies continued. The British and Americans preferred to cede all of Eritrea except the Western province to the Ethiopians as a reward for their support during World War II. The Independence Bloc of Eritrean parties consistently requested from the UN General Assembly that a referendum be held immediately to settle the Eritrean question of sovereignty.
What did Emperor Haile Selassie seek to annex in the 1950's?

Most electrification systems use overhead wires, but third rail is an option up to about 1,200 V. Third rail systems exclusively use DC distribution. The use of AC is not feasible because the dimensions of a third rail are physically very large compared with the skin depth that the alternating current penetrates to (0.3 millimetres or 0.012 inches) in a steel rail). This effect makes the resistance per unit length unacceptably high compared with the use of DC. Third rail is more compact than overhead wires and can be used in smaller-diameter tunnels, an important factor for subway systems.
What type is mostly used third rail or overhead wires?
****
The answer: overhead wires

The problem: Answer a question about this article:
In France during the Middle Ages, there were two Great Officers of the Crown of France with police responsibilities: The Marshal of France and the Constable of France. The military policing responsibilities of the Marshal of France were delegated to the Marshal's provost, whose force was known as the Marshalcy because its authority ultimately derived from the Marshal. The marshalcy dates back to the Hundred Years' 'War, and some historians trace it back to the early 12th century. Another organisation, the Constabulary (French: Connetablie), was under the command of the Constable of France. The constabulary was regularised as a military body in 1337. Under King Francis I (who reigned 15151547), the Marechaussee was merged with the Constabulary. The resulting force was also known as the Marechaussee, or, formally, the Constabulary and Marshalcy of France.
Which two entities in Medieval France had police duties?
****
The answer:
The Marshal of France and the Constable of France
