The problem: Answer a question about this article:
The bipolar junction transistor (BJT) was the most commonly used transistor in the 1960s and 70s. Even after MOSFETs became widely available, the BJT remained the transistor of choice for many analog circuits such as amplifiers because of their greater linearity and ease of manufacture. In integrated circuits, the desirable properties of MOSFETs allowed them to capture nearly all market share for digital circuits. Discrete MOSFETs can be applied in transistor applications, including analog circuits, voltage regulators, amplifiers, power transmitters and motor drivers.
What was the most frequently used transistor in the 1960s and 70s?
****
The answer: bipolar junction transistor


The problem: Answer a question about this article:
The first non-stop transatlantic crossing was made by the British airship R34 in 1919. Regular passenger service resumed in the 1920s and the discovery of helium reserves in the United States promised increased safety, but the U.S. government refused to sell the gas for this purpose. Therefore, H2 was used in the Hindenburg airship, which was destroyed in a midair fire over New Jersey on 6 May 1937. The incident was broadcast live on radio and filmed. Ignition of leaking hydrogen is widely assumed to be the cause, but later investigations pointed to the ignition of the aluminized fabric coating by static electricity. But the damage to hydrogen's reputation as a lifting gas was already done.
Who made the first non stop transatlantic crossing?

The answer: the British


The problem: Answer a question about this article:
Songbirds and their associated symbolism appear throughout the novel. The family's last name of Finch also shares Lee's mother's maiden name. The titular mockingbird is a key motif of this theme, which first appears when Atticus, having given his children air-rifles for Christmas, allows their Uncle Jack to teach them to shoot. Atticus warns them that, although they can "shoot all the bluejays they want", they must remember that "it's a sin to kill a mockingbird". Confused, Scout approaches her neighbor Miss Maudie, who explains that mockingbirds never harm other living creatures. She points out that mockingbirds simply provide pleasure with their songs, saying, "They don't do one thing but sing their hearts out for us." Writer Edwin Bruell summarized the symbolism when he wrote in 1964, "'To kill a mockingbird' is to kill that which is innocent and harmless—like Tom Robinson." Scholars have noted that Lee often returns to the mockingbird theme when trying to make a moral point.
According to Miss Maudie, which bird is never harmful?
****
The answer: mockingbird

Pope St. Gregory stigmatized Judaism and the Jewish People in many of his writings. He described Jews as enemies of Christ: "The more the Holy Spirit fills the world, the more perverse hatred dominates the souls of the Jews." He labeled all heresy as "Jewish", claiming that Judaism would "pollute [Catholics and] deceive them with sacrilegious seduction." The identification of Jews and heretics in particular occurred several times in Roman-Christian law,
Who denounced Jewish People in many of his writings?
****
The answer:
Pope St. Gregory
