Input: Read this: For maximum life, capacitors usually need to be able to handle the maximum amount of reversal that a system will experience. An AC circuit will experience 100% voltage reversal, while under-damped DC circuits will experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can dramatically shorten the life expectancy of the capacitor. Reversal ratings will often affect the design considerations for the capacitor, from the choice of dielectric materials and voltage ratings to the types of internal connections used.
Question: What does excess electric field present in the dielectric lead to?

Output: heating of both the dielectric and the conductors


Input: Read this: At Buya in Eritrea, one of the oldest hominids representing a possible link between Homo erectus and an archaic Homo sapiens was found by Italian scientists. Dated to over 1 million years old, it is the oldest skeletal find of its kind and provides a link between hominids and the earliest anatomically modern humans. It is believed that the section of the Danakil Depression in Eritrea was also a major player in terms of human evolution, and may contain other traces of evolution from Homo erectus hominids to anatomically modern humans.
Question: How far back can anatomically modern human bones be found?

Output: unanswerable


Input: Read this: Congress acted defiantly toward the Supreme Court by passing the Drug Kingpin Act of 1988 and the Federal Death Penalty Act of 1994 that made roughly fifty crimes punishable by death, including crimes that do not always involve the death of someone. Such non-death capital offenses include treason, espionage (spying for another country), and high-level drug trafficking. Since no one has yet been sentenced to death for such non-death capital offenses, the Supreme Court has not ruled on their constitutionality.
Question:  What is another term for the act of spying on another country?

Output: unanswerable


Input: Read this: Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dogs are predators and scavengers, and like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.
Question: What are a dog's teeth mainly used for?

Output:
catching and tearing
