Question: West's controversial incident the following year at the 2009 MTV Video Music Awards was arguably his biggest controversy, and led to widespread outrage throughout the music industry. During the ceremony, West crashed the stage and grabbed the microphone from winner Taylor Swift in order to proclaim that, instead, Beyoncé's video for "Single Ladies (Put a Ring on It)", nominated for the same award, was "one of the best videos of all time". He was subsequently withdrawn from the remainder of the show for his actions. West's tour with Lady Gaga was cancelled in response to the controversy, and it was suggested that the incident was partially responsible for 808s & Heartbreak's lack of nominations at the 52nd Grammy Awards.
Is there an answer to this question: What awards ceremony did Kanye not receive any nominations for after the MTV controversy?

Answer: 52nd Grammy Awards


Question: After the creation of the Commonwealth of Australia in 1901, Norfolk Island was placed under the authority of the new Commonwealth government to be administered as an external territory. During World War II, the island became a key airbase and refuelling depot between Australia and New Zealand, and New Zealand and the Solomon Islands. The airstrip was constructed by Australian, New Zealand and United States servicemen during 1942. Since Norfolk Island fell within New Zealand's area of responsibility it was garrisoned by a New Zealand Army unit known as N Force at a large Army camp which had the capacity to house a 1,500 strong force. N Force relieved a company of the Second Australian Imperial Force. The island proved too remote to come under attack during the war and N Force left the island in February 1944.
Is there an answer to this question: What minor event did Norfolk Island become an important airbase and refueling station during?

Answer: unanswerable


Question: Among his contributions to philosophy is his claim to have solved the philosophical problem of induction. He states that while there is no way to prove that the sun will rise, it is possible to formulate the theory that every day the sun will rise; if it does not rise on some particular day, the theory will be falsified and will have to be replaced by a different one. Until that day, there is no need to reject the assumption that the theory is true. Nor is it rational according to Popper to make instead the more complex assumption that the sun will rise until a given day, but will stop doing so the day after, or similar statements with additional conditions.
Is there an answer to this question: What parts of a theory are unnecessary before the simple theory is falsified?

Answer: additional conditions


Question: A DBMS has evolved into a complex software system and its development typically requires thousands of human years of development effort.[a] Some general-purpose DBMSs such as Adabas, Oracle and DB2 have been undergoing upgrades since the 1970s. General-purpose DBMSs aim to meet the needs of as many applications as possible, which adds to the complexity. However, the fact that their development cost can be spread over a large number of users means that they are often the most cost-effective approach. However, a general-purpose DBMS is not always the optimal solution: in some cases a general-purpose DBMS may introduce unnecessary overhead. Therefore, there are many examples of systems that use special-purpose databases. A common example is an email system that performs many of the functions of a general-purpose DBMS such as the insertion and deletion of messages composed of various items of data or associating messages with a particular email address; but these functions are limited to what is required to handle email and don't provide the user with all of the functionality that would be available using a general-purpose DBMS.
Is there an answer to this question: Name three DBMSs that have been used since the 1970s.

Answer:
Adabas, Oracle and DB2
