Problem: Start and end dates vary with location and year. Since 1996 European Summer Time has been observed from the last Sunday in March to the last Sunday in October; previously the rules were not uniform across the European Union. Starting in 2007, most of the United States and Canada observe DST from the second Sunday in March to the first Sunday in November, almost two-thirds of the year. The 2007 US change was part of the Energy Policy Act of 2005; previously, from 1987 through 2006, the start and end dates were the first Sunday in April and the last Sunday in October, and Congress retains the right to go back to the previous dates now that an energy-consumption study has been done. Proponents for permanently retaining November as the month for ending DST point to Halloween as a reason to delay the change in order to allow extra daylight for the evening of October 31.
What act in the U.S. brought about the 2007 change in DST policy?
The answer is the following: the Energy Policy Act of 2005

Problem: The States General of the United Provinces were in control of the Dutch East India Company (VOC) and the Dutch West India Company (WIC), but some shipping expeditions were initiated by some of the provinces, mostly Holland and/or Zeeland.
Some shipping expeditions were mostly initiated by which provinces?
The answer is the following: Holland and/or Zeeland

Problem: The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world and brought renewed attention to developing solar technologies. Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the US (SERI, now NREL), Japan (NEDO), and Germany (Fraunhofer Institute for Solar Energy Systems ISE).
What is the name of the solar energy research facility in Japan?
The answer is the following: NEDO

Problem: With the collapse of Roman rule in the early 5th century, London ceased to be a capital and the walled city of Londinium was effectively abandoned, although Roman civilisation continued in the St Martin-in-the-Fields area until around 450. From around 500, an Anglo-Saxon settlement known as Lundenwic developed in the same area, slightly to the west of the old Roman city. By about 680, it had revived sufficiently to become a major port, although there is little evidence of large-scale production of goods. From the 820s the town declined because of repeated Viking invasions. There are three recorded Viking assaults on London; two of which were successful in 851 and 886 AD, although they were defeated during the attack of 994 AD.
By the late 7th century, what was a main function of Lundenwic?
The answer is the following:
a major port
