Problem: Please answer a question about the following article about Warsaw Pact:
The eight member countries of the Warsaw Pact pledged the mutual defense of any member who would be attacked. Relations among the treaty signatories were based upon mutual non-intervention in the internal affairs of the member countries, respect for national sovereignty, and political independence. However, almost all governments of those member states were indirectly controlled by the Soviet Union.
How many countries formed the initial Warsaw Pact membership?
A: eight
Problem: Please answer a question about the following article about New Delhi:
Soon Lutyens started considering other places. Indeed, the Delhi Town Planning Committee, set up to plan the new imperial capital, with George Swinton as chairman and John A. Brodie and Lutyens as members, submitted reports for both North and South sites. However, it was rejected by the Viceroy when the cost of acquiring the necessary properties was found to be too high. The central axis of New Delhi, which today faces east at India Gate, was previously meant to be a north-south axis linking the Viceroy's House at one end with Paharganj at the other. During the project's early years, many tourists believed it was a gate from Earth to Heaven itself. Eventually, owing to space constraints and the presence of a large number of heritage sites in the North side, the committee settled on the South site. A site atop the Raisina Hill, formerly Raisina Village, a Meo village, was chosen for the Rashtrapati Bhawan, then known as the Viceroy's House. The reason for this choice was that the hill lay directly opposite the Dinapanah citadel, which was also considered the site of Indraprastha, the ancient region of Delhi. Subsequently, the foundation stone was shifted from the site of Delhi Durbar of 19111912, where the Coronation Pillar stood, and embedded in the walls of the forecourt of the Secretariat. The Rajpath, also known as King's Way, stretched from the India Gate to the Rashtrapati Bhawan. The Secretariat building, the two blocks of which flank the Rashtrapati Bhawan and houses ministries of the Government of India, and the Parliament House, both designed by Herbert Baker, are located at the Sansad Marg and run parallel to the Rajpath.
Raisina Hill lay directly opposite what religious site?
A: Dinapanah citadel
Problem: Please answer a question about the following article about Printed circuit board:
The printed circuit board industry defines heavy copper as layers exceeding three ounces of copper, or approximately 0.0042 inches (4.2 mils, 105 m) thick. PCB designers and fabricators often use heavy copper when design and manufacturing circuit boards in order to increase current-carrying capacity as well as resistance to thermal strains. Heavy copper plated vias transfer heat to external heat sinks. IPC 2152 is a standard for determining current-carrying capacity of printed circuit board traces.
About how thick would a PCB layer be if it contained three oz. of copper?
A: 0.0042 inches
Problem: Please answer a question about the following article about Alps:
High levels of precipitation cause the glaciers to descend to permafrost levels in some areas whereas in other, more arid regions, glaciers remain above about the 3,500 m (11,483 ft) level. The 1,817 square kilometres (702 sq mi) of the Alps covered by glaciers in 1876 had shrunk to 1,342 km2 (518 sq mi) by 1973, resulting in decreased river run-off levels. Forty percent of the glaciation in Austria has disappeared since 1850, and 30% of that in Switzerland.
What cause the glaciers to descend to permafrost levels in some areas?
A:
High levels of precipitation
