Problem: Law of the United States:

Notably, the most broadly influential innovation of 20th-century American tort law was the rule of strict liability for defective products, which originated with judicial glosses on the law of warranty. In 1963, Roger J. Traynor of the Supreme Court of California threw away legal fictions based on warranties and imposed strict liability for defective products as a matter of public policy in the landmark case of Greenman v. Yuba Power Products. The American Law Institute subsequently adopted a slightly different version of the Greenman rule in Section 402A of the Restatement (Second) of Torts, which was published in 1964 and was very influential throughout the United States. Outside the U.S., the rule was adopted by the European Economic Community in the Product Liability Directive of July 1985 by Australia in July 1992 and by Japan in June 1994.

What is one of the most influential changes to tort law?

A: rule of strict liability for defective products

Nasser's involvement in political activity increased throughout his school years, such that he only attended 45 days of classes during his last year of secondary school. Despite it having the almost unanimous backing of Egypt's political forces, Nasser strongly objected to the 1936 Anglo-Egyptian Treaty because it stipulated the continued presence of British military bases in the country. Nonetheless, political unrest in Egypt declined significantly and Nasser resumed his studies at al-Nahda, where he received his leaving certificate later that year.
How many days did Nasser attend classes in his senior year?
A: 45


Context and question: Canadian bitumen does not differ substantially from oils such as Venezuelan extra-heavy and Mexican heavy oil in chemical composition, and the real difficulty is moving the extremely viscous bitumen through oil pipelines to the refinery. Many modern oil refineries are extremely sophisticated and can process non-upgraded bitumen directly into products such as gasoline, diesel fuel, and refined asphalt without any preprocessing. This is particularly common in areas such as the US Gulf coast, where refineries were designed to process Venezuelan and Mexican oil, and in areas such as the US Midwest where refineries were rebuilt to process heavy oil as domestic light oil production declined. Given the choice, such heavy oil refineries usually prefer to buy bitumen rather than synthetic oil because the cost is lower, and in some cases because they prefer to produce more diesel fuel and less gasoline. By 2015 Canadian production and exports of non-upgraded bitumen exceeded that of synthetic crude oil at over 1.3 million barrels (210×10^3 m3) per day, of which about 65% was exported to the United States.
What industry is capable of refining bitumen directly into gasoline without preprocessing?
Answer: modern oil refineries

QUES: In 1768 Russian-backed Ukrainian Haidamaks, pursuing Polish confederates, entered Balta, an Ottoman-controlled town on the border of Bessarabia in Ukraine, and massacred its citizens and burned the town to the ground. This action provoked the Ottoman Empire into the Russo-Turkish War of 1768–1774. The Treaty of Küçük Kaynarca of 1774 ended the war and provided freedom to worship for the Christian citizens of the Ottoman-controlled provinces of Wallachia and Moldavia. By the late 18th century, a number of defeats in several wars with Russia led some people in the Ottoman Empire to conclude that the reforms of Peter the Great had given the Russians an edge, and the Ottomans would have to keep up with Western technology in order to avoid further defeats.

During what years was the Russo-Turkish war?
What is the answer?
ANS:
1768–1774
