Context and question: Three weeks later, on May 5, 1961, Alan Shepard became the first American in space, launched in a ballistic trajectory on Mercury-Redstone 3, in a spacecraft he named Freedom 7. Though he did not achieve orbit like Gagarin, he was the first person to exercise manual control over his spacecraft's attitude and retro-rocket firing. After his successful return, Shepard was celebrated as a national hero, honored with parades in Washington, New York and Los Angeles, and received the NASA Distinguished Service Medal from President John F. Kennedy.
Which president awarded Alan Shepard the NASA Distinguished Service Medal?
Answer: John F. Kennedy
Context and question: Instead, it is often desired to have an antenna whose impedance does not vary so greatly over a certain bandwidth. It turns out that the amount of reactance seen at the terminals of a resonant antenna when the frequency is shifted, say, by 5%, depends very much on the diameter of the conductor used. A long thin wire used as a half-wave dipole (or quarter wave monopole) will have a reactance significantly greater than the resistive impedance it has at resonance, leading to a poor match and generally unacceptable performance. Making the element using a tube of a diameter perhaps 1/50 of its length, however, results in a reactance at this altered frequency which is not so great, and a much less serious mismatch which will only modestly damage the antenna's net performance. Thus rather thick tubes are typically used for the solid elements of such antennas, including Yagi-Uda arrays.
What characteristic would be better if it were steady?
Answer: reactance
Context and question: Kerry was arrested on May 30, 1971, during a VVAW march to honor American POWs held captive by North Vietnam. The march was planned as a multi-day event from Concord to Boston, and while in Lexington, participants tried to camp on the village green. At 2:30 a.m., local and state police arrested 441 demonstrators, including Kerry, for trespassing. All were given the Miranda Warning and were hauled away on school buses to spend the night at the Lexington Public Works Garage. Kerry and the other protesters later paid a $5 fine, and were released. The mass arrests caused a community backlash and ended up giving positive coverage to the VVAW.
Why were the protesters arrested?
Answer:
tried to camp on the village green
