Problem: Development of the methods used in modern printed circuit boards started early in the 20th century. In 1903, a German inventor, Albert Hanson, described flat foil conductors laminated to an insulating board, in multiple layers. Thomas Edison experimented with chemical methods of plating conductors onto linen paper in 1904. Arthur Berry in 1913 patented a print-and-etch method in Britain, and in the United States Max Schoop obtained a patent to flame-spray metal onto a board through a patterned mask. Charles Ducas in 1927 patented a method of electroplating circuit patterns.
Who was the German inventor who wrote in 1903 about conductors being laminated in layers to a board?
The answer is the following: Albert Hanson

Problem: Throughout his presidency, Eisenhower adhered to a political philosophy of dynamic conservatism. A self-described "progressive conservative," he continued all the major New Deal programs still in operation, especially Social Security. He expanded its programs and rolled them into a new cabinet-level agency, the Department of Health, Education and Welfare, while extending benefits to an additional ten million workers. He implemented integration in the Armed Services in two years, which had not been completed under Truman.
How many people were added to the Social Security rolls by Eisenhower?
The answer is the following: ten million

Problem: The meaning of federalism, as a political movement, and of what constitutes a 'federalist', varies with country and historical context.[citation needed] Movements associated with the establishment or development of federations can exhibit either centralising or decentralising trends.[citation needed] For example, at the time those nations were being established, factions known as "federalists" in the United States and Australia advocated the formation of strong central government. Similarly, in European Union politics, federalists mostly seek greater EU integration. In contrast, in Spain and in post-war Germany, federal movements have sought decentralisation: the transfer of power from central authorities to local units. In Canada, where Quebec separatism has been a political force for several decades, the "federalist" impulse aims to keep Quebec inside Canada.
What countries advocate for a strong central government?
The answer is the following: United States and Australia

Problem: The Houston area is a leading center for building oilfield equipment. Much of its success as a petrochemical complex is due to its busy ship channel, the Port of Houston. In the United States, the port ranks first in international commerce and tenth among the largest ports in the world. Unlike most places, high oil and gasoline prices are beneficial for Houston's economy, as many of its residents are employed in the energy industry. Houston is the beginning or end point of numerous oil, gas, and products pipelines:
What lines begin or end in Houston?
The answer is the following:
pipelines
