Problem: Please answer a question about the following article about Exhibition game:
The Arena Football League briefly had a two-game exhibition season in the early 2000s, a practice that ended in 2003 with a new television contract. Exhibition games outside of a structured season are relatively common among indoor American football leagues; because teams switch leagues frequently at that level of play, it is not uncommon to see some of the smaller leagues schedule exhibition games against teams that are from another league, about to join the league as a probational franchise, or a semi-pro outdoor team to fill holes in a schedule.
What type of league commonly plays unstructured exhibition games?
A: indoor American football leagues
Problem: Please answer a question about the following article about Light-emitting diode:
The currentvoltage characteristic of an LED is similar to other diodes, in that the current is dependent exponentially on the voltage (see Shockley diode equation). This means that a small change in voltage can cause a large change in current. If the applied voltage exceeds the LED's forward voltage drop by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED. The typical solution is to use constant-current power supplies to keep the current below the LED's maximum current rating. Since most common power sources (batteries, mains) are constant-voltage sources, most LED fixtures must include a power converter, at least a current-limiting resistor. However, the high resistance of three-volt coin cells combined with the high differential resistance of nitride-based LEDs makes it possible to power such an LED from such a coin cell without an external resistor.
What is a constant-voltage source?
A: batteries
Problem: Please answer a question about the following article about The Legend of Zelda: Twilight Princess:
Ganondorf then revives, and Midna teleports Link and Zelda outside the castle so she can hold him off with the Fused Shadows. However, as Hyrule Castle collapses, it is revealed that Ganondorf was victorious as he crushes Midna's helmet. Ganondorf engages Link on horseback, and, assisted by Zelda and the Light Spirits, Link eventually knocks Ganondorf off his horse and they duel on foot before Link strikes down Ganondorf and plunges the Master Sword into his chest. With Ganondorf dead, the Light Spirits not only bring Midna back to life, but restore her to her true form. After bidding farewell to Link and Zelda, Midna returns home before destroying the Mirror of Twilight with a tear to maintain balance between Hyrule and the Twilight Realm. Near the end, as Hyrule Castle is rebuilt, Link is shown leaving Ordon Village heading to parts unknown.
To what part of his body does Link deliver the killing blow to Ganondorf?
A: chest
Problem: Please answer a question about the following article about Karl Popper:
In a book called Science Versus Crime, Houck writes that Popper's falsificationism can be questioned logically: it is not clear how Popper would deal with a statement like "for every metal, there is a temperature at which it will melt." The hypothesis cannot be falsified by any possible observation, for there will always be a higher temperature than tested at which the metal may in fact melt, yet it seems to be a valid scientific hypothesis. These examples were pointed out by Carl Gustav Hempel. Hempel came to acknowledge that Logical Positivism's verificationism was untenable, but argued that falsificationism was equally untenable on logical grounds alone. The simplest response to this is that, because Popper describes how theories attain, maintain and lose scientific status, individual consequences of currently accepted scientific theories are scientific in the sense of being part of tentative scientific knowledge, and both of Hempel's examples fall under this category. For instance, atomic theory implies that all metals melt at some temperature.
Who wrote the book Science Versus Crime which challenged the logic of falsificationism?
A:
Houck
