Question: A lone naked human is at a physical disadvantage to other comparable apex predators in areas such as speed, bone density, weight, and physical strength. Humans also lack innate weaponry such as claws. Without crafted weapons, society, or cleverness, a lone human can easily be defeated by fit predatory animals, such as wild dogs, big cats and bears (see Man-eater). However, humans are not solitary creatures; they are social animals with highly developed social behaviors. Early humans, such as Homo erectus, have been using stone tools and weapons for well over a million years. Anatomically modern humans have been apex predators since they first evolved, and many species of carnivorous megafauna actively avoid interacting with humans; the primary environmental competitor for a human is other humans. The one subspecies of carnivorous megafauna that does interact frequently with humans in predatory roles is the domestic dog, but usually as a partner in predation especially if they hunt together. Cannibalism has occurred in various places, among various cultures, and for various reasons. At least a few people, such as the Donner party, are said to have resorted to it in desperation.
Is there an answer to this question: How long have bears been apex predators?

Answer: unanswerable


Question: Described as being "sexy, seductive and provocative" when performing on stage, Beyoncé has said that she originally created the alter ego "Sasha Fierce" to keep that stage persona separate from who she really is. She described Sasha as being "too aggressive, too strong, too sassy [and] too sexy", stating, "I'm not like her in real life at all." Sasha was conceived during the making of "Crazy in Love", and Beyoncé introduced her with the release of her 2008 album I Am... Sasha Fierce. In February 2010, she announced in an interview with Allure magazine that she was comfortable enough with herself to no longer need Sasha Fierce. However, Beyoncé announced in May 2012 that she would bring her back for her Revel Presents: Beyoncé Live shows later that month.
Is there an answer to this question: Sasha Fierce was created during the making of what song?

Answer: Crazy in Love


Question: Many other databases have application software that accesses the database on behalf of end-users, without exposing the DBMS interface directly. Application programmers may use a wire protocol directly, or more likely through an application programming interface. Database designers and database administrators interact with the DBMS through dedicated interfaces to build and maintain the applications' databases, and thus need some more knowledge and understanding about how DBMSs operate and the DBMSs' external interfaces and tuning parameters.
Is there an answer to this question: How are many databases accessed?

Answer:
application software
