Problem: Please answer a question about the following article about Israel:
In 1950 Egypt closed the Suez Canal to Israeli shipping and tensions mounted as armed clashes took place along Israel's borders. During the 1950s, Israel was frequently attacked by Palestinian fedayeen, nearly always against civilians, mainly from the Egyptian-occupied Gaza Strip, leading to several Israeli counter-raids. In 1956, Great Britain and France aimed at regaining control of the Suez Canal, which the Egyptians had nationalized (see the Suez Crisis). The continued blockade of the Suez Canal and Straits of Tiran to Israeli shipping, together with the growing amount of Fedayeen attacks against Israel's southern population, and recent Arab grave and threatening statements, prompted Israel to attack Egypt. Israel joined a secret alliance with Great Britain and France and overran the Sinai Peninsula but was pressured to withdraw by the United Nations in return for guarantees of Israeli shipping rights in the Red Sea via the Straits of Tiran and the Canal[citation needed]. The war resulted in significant reduction of Israeli border infiltration.
When did Egypt close the Suez Canal to Israel?
A: 1950
Problem: Please answer a question about the following article about Detroit:
Jobs expanded so rapidly that 400,000 people were attracted to the city from 1941 to 1943, including 50,000 blacks in the second wave of the Great Migration, and 350,000 whites, many of them from the South. Some European immigrants and their descendants feared black competition for jobs and housing. The federal government prohibited discrimination in defense work but when in June 1943, Packard promoted three blacks to work next to whites on its assembly lines, 25,000 whites walked off the job. The Detroit race riot of 1943 took place three weeks after the Packard plant protest. Over the course of three days, 34 people were killed, of whom 25 were African American, and approximately 600 were injured, 75% black people.
How many people were killed in the race riot of 1943?
A: 34
Problem: Please answer a question about the following article about High-definition television:
PAL, SECAM and NTSC frame rates technically apply only to analogue standard definition television, not to digital or high definition broadcasts. However, with the roll out of digital broadcasting, and later HDTV broadcasting, countries retained their heritage systems. HDTV in former PAL and SECAM countries operates at a frame rate of 25/50 Hz, while HDTV in former NTSC countries operates at 30/60 Hz.
In former NTSC countries, what frame rate does HDTV operate at?
A: 30/60 Hz
Problem: Please answer a question about the following article about Tuberculosis:
It is the most widely used vaccine worldwide, with more than 90% of all children being vaccinated. The immunity it induces decreases after about ten years. As tuberculosis is uncommon in most of Canada, the United Kingdom, and the United States, BCG is administered only to those people at high risk. Part of the reasoning against the use of the vaccine is that it makes the tuberculin skin test falsely positive, reducing the test's use in screening. A number of new vaccines are currently in development.
In addition to the U.S. and Canada, what European country sees very few tuberculosis infections?
A:
the United Kingdom
