Extract the answer to the question from the following context. Question: What is more independent than something else? Context: LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.
Ans: Zener diode

Extract the answer to the question from the following context. Question: Which of the following is not a street name: Lucas Place, Robert Brookings, or Locust Street? Context: Washington University spent its first half century in downtown St. Louis bounded by Washington Ave., Lucas Place, and Locust Street. By the 1890s, owing to the dramatic expansion of the Manual School and a new benefactor in Robert Brookings, the University began to move west. The University Board of Directors began a process to find suitable ground and hired the landscape architecture firm Olmsted, Olmsted & Eliot of Boston. A committee of Robert S. Brookings, Henry Ware Eliot, and William Huse found a site of 103 acres (41.7 ha) just beyond Forest Park, located west of the city limits in St. Louis County. The elevation of the land was thought to resemble the Acropolis and inspired the nickname of "Hilltop" campus, renamed the Danforth campus in 2006 to honor former chancellor William H. Danforth.
Ans: Robert Brookings

Extract the answer to the question from the following context. Question: Of Halcyon and Space Ace, which was a game console? Context: The format's instant-access capability made it possible for a new breed of LaserDisc-based video arcade games and several companies saw potential in using LaserDiscs for video games in the 1980s and 1990s, beginning in 1983 with Sega's Astron Belt. American Laser Games and Cinematronics produced elaborate arcade consoles that used the random-access features to create interactive movies such as Dragon's Lair and Space Ace. Similarly, the Pioneer Laseractive and Halcyon were introduced as home video game consoles that used LaserDisc media for their software.
Ans: Halcyon
