Problem: The Chronicle provides a mythic tale of Oleg's death. A sorcerer prophesies that the death of the Grand Prince would be associated with a certain horse. Oleg has the horse sequestered, and it later dies. Oleg goes to visit the horse and stands over the carcass, gloating that he had outlived the threat, when a snake strikes him from among the bones, and he soon becomes ill and dies. The Chronicle reports that Prince Igor succeeded Oleg in 913, and after some brief conflicts with the Drevlians and the Pechenegs, a period of peace ensued for over twenty years.
What does Oleg do to his horse?
The answer is the following: has the horse sequestered

Problem: The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). Early carbon filaments had a negative temperature coefficient of resistance — as they got hotter, their electrical resistance decreased. This made the lamp sensitive to fluctuations in the power supply, since a small increase of voltage would cause the filament to heat up, reducing its resistance and causing it to draw even more power and heat even further. In the "flashing" process, carbon filaments were heated by current passing through them while in an evacuated vessel containing hydrocarbon vapor (usually gasoline). The carbon deposited on the filament by this treatment improved the uniformity and strength of filaments as well as their efficiency. A metallized or "graphitized" filament was first heated in a high-temperature oven before flashing and lamp assembly. This transformed the carbon into graphite which further strengthened and smoothed the filament. This also changed the filament to have a positive temperature coefficient, like a metallic conductor, and helped stabilize the lamp's power consumption, temperature and light output against minor variations in supply voltage.
What material were the first light bulb filaments made from?
The answer is the following: carbon

Problem: The GameCube and Wii versions feature several minor differences in their controls. The Wii version of the game makes use of the motion sensors and built-in speaker of the Wii Remote. The speaker emits the sounds of a bowstring when shooting an arrow, Midna's laugh when she gives advice to Link, and the series' trademark "chime" when discovering secrets. The player controls Link's sword by swinging the Wii Remote. Other attacks are triggered using similar gestures with the Nunchuk. Unique to the GameCube version is the ability for the player to control the camera freely, without entering a special "lookaround" mode required by the Wii; however, in the GameCube version, only two of Link's secondary weapons can be equipped at a time, as opposed to four in the Wii version.[g]
Aside from the sword, what is another weapon that Link can use?
The answer is the following: Nunchuk

Problem: When the Xbox 360 was released, Microsoft's online gaming service Xbox Live was shut down for 24 hours and underwent a major upgrade, adding a basic non-subscription service called Xbox Live Silver (later renamed Xbox Live Free) to its already established premium subscription-based service (which was renamed Gold). Xbox Live Free is included with all SKUs of the console. It allows users to create a user profile, join on message boards, and access Microsoft's Xbox Live Arcade and Marketplace and talk to other members. A Live Free account does not generally support multiplayer gaming; however, some games that have rather limited online functions already, (such as Viva Piñata) or games that feature their own subscription service (e.g. EA Sports games) can be played with a Free account. Xbox Live also supports voice the latter a feature possible with the Xbox Live Vision.
What key feature is not supported by the free version of Live?
The answer is the following:
multiplayer gaming
