Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Infants do not have the language ability to report on their memories and so verbal reports cannot be used to assess very young children's memory. Throughout the years, however, researchers have adapted and developed a number of measures for assessing both infants' recognition memory and their recall memory. Habituation and operant conditioning techniques have been used to assess infants' recognition memory and the deferred and elicited imitation techniques have been used to assess infants' recall memory.
What techniques have not been used to assess infants' recognition memory?
A: unanswerable

Context and question: Whittaker was unsuited for the role and soon retired. Stewart and Harlan were conservative Republicans, while Brennan was a Democrat who became a leading voice for liberalism. In selecting a Chief Justice, Eisenhower looked for an experienced jurist who could appeal to liberals in the party as well as law-and-order conservatives, noting privately that Warren "represents the kind of political, economic, and social thinking that I believe we need on the Supreme Court ... He has a national name for integrity, uprightness, and courage that, again, I believe we need on the Court". In the next few years Warren led the Court in a series of liberal decisions that revolutionized the role of the Court.
What party did Brennan belong to?
Answer: Democrat

Question: The first Sky television rights agreement was worth 304 million over five seasons. The next contract, negotiated to start from the 199798 season, rose to 670 million over four seasons. The third contract was a 1.024 billion deal with BSkyB for the three seasons from 200102 to 200304. The league brought in 320 million from the sale of its international rights for the three-year period from 200405 to 200607. It sold the rights itself on a territory-by-territory basis. Sky's monopoly was broken from August 2006 when Setanta Sports was awarded rights to show two out of the six packages of matches available. This occurred following an insistence by the European Commission that exclusive rights should not be sold to one television company. Sky and Setanta paid a total of 1.7 billion, a two-thirds increase which took many commentators by surprise as it had been widely assumed that the value of the rights had levelled off following many years of rapid growth. Setanta also hold rights to a live 3 pm match solely for Irish viewers. The BBC has retained the rights to show highlights for the same three seasons (on Match of the Day) for 171.6 million, a 63 per cent increase on the 105 million it paid for the previous three-year period. Sky and BT have agreed to jointly pay 84.3 million for delayed television rights to 242 games (that is the right to broadcast them in full on television and over the internet) in most cases for a period of 50 hours after 10 pm on matchday. Overseas television rights fetched 625 million, nearly double the previous contract. The total raised from these deals is more than 2.7 billion, giving Premier League clubs an average media income from league games of around 40 million-a-year from 2007 to 2010.
Is there an answer to this question: How much was the second contract worth over a three season period?

Answer: unanswerable

Question: On 1 September 1939, two days before Britain declared war on Germany, the station was taken off air with little warning; the government was concerned that the VHF transmissions would act as a beacon to enemy aircraft homing in on London. Also, many of the television service's technical staff and engineers would be needed for the war effort, in particular on the radar programme. The last programme transmitted was a Mickey Mouse cartoon, Mickey's Gala Premier (1933), which was followed by test transmissions; this account refuted the popular memory according to which broadcasting was suspended before the end of the cartoon.
Is there an answer to this question: What were many of the television service's technical radar staff needed for in the war effort?

Answer:
unanswerable
