Problem: The two main denominations of Islam are the Sunni and Shia sects. They differ primarily upon of how the life of the ummah ("faithful") should be governed, and the role of the imam. These two main differences stem from the understanding of which hadith are to interpret the Quran. Sunnis believe the true political successor of the Prophet in Sunnah is based on ٍShura (consultation) at the Saqifah which selected Abu Bakr, father of the Prophet's favourite wife, 'A'ishah, to lead the Islamic community while the religious succession ceased to exist on account of finality of Prophethood. Shia on the other hand believe that the true political as well as religious successor is Ali ibn Abi Talib, husband of the Prophet's daughter Fatimah (designated by the Prophet).
What type of sucessor do the Shia believe Abu Bakr was?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
It has been observed that well-fed predator animals in a lax captivity (for instance, pet or farm animals) will usually differentiate between putative prey animals who are familiar co-inhabitants in the same human area from wild ones outside the area. This interaction can range from peaceful coexistence to close companionship; motivation to ignore the predatory instinct may result from mutual advantage or fear of reprisal from human masters who have made clear that harming co-inhabitants will not be tolerated. Pet cats and pet mice, for example, may live together in the same human residence without incident as companions. Pet cats and pet dogs under human mastership often depend on each other for warmth, companionship, and even protection, particularly in rural areas.
What can people from rural areas differentiate captive animals from?
A: unanswerable

Question: Kinect is a "controller-free gaming and entertainment experience" for the Xbox 360. It was first announced on June 1, 2009 at the Electronic Entertainment Expo, under the codename, Project Natal. The add-on peripheral enables users to control and interact with the Xbox 360 without a game controller by using gestures, spoken commands and presented objects and images. The Kinect accessory is compatible with all Xbox 360 models, connecting to new models via a custom connector, and to older ones via a USB and mains power adapter. During their CES 2010 keynote speech, Robbie Bach and Microsoft CEO Steve Ballmer went on to say that Kinect will be released during the holiday period (November–January) and it will work with every 360 console.

Problem: Iran:

On November 4, 1979, a group of students seized the United States Embassy and took the embassy with 52 personnel and citizens hostage, after the United States refused to return Mohammad Reza Pahlavi to Iran to face trial in the court of the new regime. Attempts by the Jimmy Carter administration to negotiate for the release of the hostages, and a failed rescue attempt, helped force Carter out of office and brought Ronald Reagan to power. On Jimmy Carter's final day in office, the last hostages were finally set free as a result of the Algiers Accords.
