input question: Extract the answer to the question from the following context. Question: What is Pacala studying? Context: The incentive to use 100% renewable energy, for electricity, transport, or even total primary energy supply globally, has been motivated by global warming and other ecological as well as economic concerns. The Intergovernmental Panel on Climate Change has said that there are few fundamental technological limits to integrating a portfolio of renewable energy technologies to meet most of total global energy demand. In reviewing 164 recent scenarios of future renewable energy growth, the report noted that the majority expected renewable sources to supply more than 17% of total energy by 2030, and 27% by 2050; the highest forecast projected 43% supplied by renewables by 2030 and 77% by 2050. Renewable energy use has grown much faster than even advocates anticipated. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply. Also, Professors S. Pacala and Robert H. Socolow have developed a series of "stabilization wedges" that can allow us to maintain our quality of life while avoiding catastrophic climate change, and "renewable energy sources," in aggregate, constitute the largest number of their "wedges."???
output answer: a series of "stabilization wedges" that can allow us to maintain our quality of life while avoiding catastrophic climate change

Context: In Britain, Willett's 1907 proposal used the term daylight saving, but by 1911 the term summer time replaced daylight saving time in draft legislation. Continental Europe uses similar phrases, such as Sommerzeit in Germany, zomertijd in Dutch-speaking regions, kesaaika in Finland, horario de verano or hora de verano in Spain and heure d'ete in France, whereas in Italy the term is ora legale, that is, legal time (legally enforced time) as opposed to "ora solare", solar time, in winter.???
output answer: Sommerzeit in Germany, zomertijd in Dutch-speaking regions, kesaaika in Finland, horario de verano or hora de verano in Spain and heure d'ete in France, whereas in Italy the term is ora legale

input question: Extract the answer to the question from the following context. Question: What policy changed Context: The largest expansion of comprehensive schools in 1965 resulted from a policy decision taken in 1965 by Anthony Crosland, Secretary of State for Education in the 19641970 Labour government. The policy decision was implemented by Circular 10/65, an instruction to local education authorities to plan for conversion. Students sat the 11+ examination in their last year of primary education and were sent to one of a secondary modern, secondary technical or grammar school depending on their perceived ability. Secondary technical schools were never widely implemented and for 20 years there was a virtual bipartite system which saw fierce competition for the available grammar school places, which varied between 15% and 25% of total secondary places, depending on location.[citation needed]???

Circular 10/65
