QUES: Multi-layer printed circuit boards have trace layers inside the board. This is achieved by laminating a stack of materials in a press by applying pressure and heat for a period of time. This results in an inseparable one piece product. For example, a four-layer PCB can be fabricated by starting from a two-sided copper-clad laminate, etch the circuitry on both sides, then laminate to the top and bottom pre-preg and copper foil. It is then drilled, plated, and etched again to get traces on top and bottom layers.
If you started with a two-sided laminate etched on either side, laminated to the top and bottom, and processed it again to get traces on the outside layers, how many layers would your final PCB have?

ANS: four

QUES: His next relationship was with Herta Haas, whom he married in 1940. Broz left for Belgrade after the April War, leaving Haas pregnant. In May 1941, she gave birth to their son, Aleksandar "Miso" Broz.

Haas and Tito suddenly parted company in 1943 in Jajce during the second meeting of AVNOJ after she reportedly walked in on him and Davorjanka. The last time Haas saw Broz was in 1946. Davorjanka died of tuberculosis in 1946 and Tito insisted that she be buried in the backyard of the Beli Dvor, his Belgrade residence.

QUES: Prior to 1871, the government of the United States regularly entered into treaties with Native Americans but the Indian Appropriations Act of March 3, 1871 (ch. 120, 16 Stat. 563) had a rider (25 U.S.C. 71) attached that effectively ended the President's treaty making by providing that no Indian nation or tribe shall be acknowledged as an independent nation, tribe, or power with whom the United States may contract by treaty. The federal government continued to provide similar contractual relations with the Indian tribes after 1871 by agreements, statutes, and executive orders.
A rider to the Indian Appropriations Act of 1871 provided that the US government could not do what with an Indian nation?

ANS: contract by treaty

QUES: During the late 19th Century the Jadidists established themselves as an Islamic social movement throughout the region. Although the Jadidists were pro-modernization and not necessarily anti-Russian the Russians viewed the movement as a threat.[citation needed] Russian troops were required to restore order during uprisings against the Khanate of Kokand between 1910 and 1913. Further violence occurred in July 1916 when demonstrators attacked Russian soldiers in Khujand over the threat of forced conscription during World War I. Despite Russian troops quickly bringing Khujand back under control, clashes continued throughout the year in various locations in Tajikistan.[citation needed]
Which group was anti-modernization?
