Here is a question about this article: The city is home to 15 am and FM radio stations, two of which are French-language stations. St. John's is the only Canadian city served by radio stations whose call letters do not all begin with the letter C. The ITU prefix VO was assigned to the Dominion of Newfoundland before the province joined Canadian Confederation in 1949, and three AM stations kept their existing call letters. However, other commercial radio stations in St. John's which went to air after 1949 use the same range of prefixes (CFCK) currently in use elsewhere in Canada, with the exception of VOCM-FM, which was permitted to adopt the VOCM callsign because of its corporate association with the AM station that already bore that callsign. VO also remains in use in amateur radio.
What is the answer to this question: How many French-language stations does the city have?
****
So... two

The problem: Answer a question about this article:
On the domestic front, he covertly opposed Joseph McCarthy and contributed to the end of McCarthyism by openly invoking the modern expanded version of executive privilege. He otherwise left most political activity to his Vice President, Richard Nixon. He was a moderate conservative who continued New Deal agencies and expanded Social Security. He also launched the Interstate Highway System, the Defense Advanced Research Projects Agency (DARPA), the establishment of strong science education via the National Defense Education Act, and encouraged peaceful use of nuclear power via amendments to the Atomic Energy Act.
Who served as Eisenhower's vice president?
****
The answer: Nixon

Problem: Please answer a question about the following article about Biodiversity:
A 2007 study conducted by the National Science Foundation found that biodiversity and genetic diversity are codependentthat diversity among species requires diversity within a species, and vice versa. "If any one type is removed from the system, the cycle can break down, and the community becomes dominated by a single species." At present, the most threatened ecosystems are found in fresh water, according to the Millennium Ecosystem Assessment 2005, which was confirmed by the "Freshwater Animal Diversity Assessment", organised by the biodiversity platform, and the French Institut de recherche pour le developpement (MNHNP).
In which year was the study published that found biodiversity and genetic diversity are codependent?
A: 2007

One of the major developments in the military sphere during the Late Middle Ages was the increased use of infantry and light cavalry. The English also employed longbowmen, but other countries were unable to create similar forces with the same success. Armour continued to advance, spurred by the increasing power of crossbows, and plate armour was developed to protect soldiers from crossbows as well as the hand-held guns that were developed. Pole arms reached new prominence with the development of the Flemish and Swiss infantry armed with pikes and other long spears.

What influenced the increasing development of armor?
Answer: the increasing power of crossbows

Problem: Ashkenazi Jews represent the bulk of modern Jewry, with at least 70% of Jews worldwide (and up to 90% prior to World War II and the Holocaust). As a result of their emigration from Europe, Ashkenazim also represent the overwhelming majority of Jews in the New World continents, in countries such as the United States, Canada, Argentina, Australia, and Brazil. In France, the immigration of Jews from Algeria (Sephardim) has led them to outnumber the Ashkenazim. Only in Israel is the Jewish population representative of all groups, a melting pot independent of each group's proportion within the overall world Jewish population.
Why does Ashkenazim represent the overwhelming majority of Jews in the New World continents?
The answer is the following: As a result of their emigration from Europe

Input: Article: The net quality of a ground reflection depends on the topography of the surface. When the irregularities of the surface are much smaller than the wavelength, we are in the regime of specular reflection, and the receiver sees both the real antenna and an image of the antenna under the ground due to reflection. But if the ground has irregularities not small compared to the wavelength, reflections will not be coherent but shifted by random phases. With shorter wavelengths (higher frequencies), this is generally the case.

Now answer this question: What is the reason for the receiver seeing both the ral antenna and image of the antenna?

Output:
reflection
