Several studies have suggested that DST increases motor fuel consumption. The 2008 DOE report found no significant increase in motor gasoline consumption due to the 2007 United States extension of DST.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What happened regarding DST in 2007 in the United States that probably led to the DOE investigation?
Ah, so.. extension of DST

In the political realm, historians debate whether Napoleon was "an enlightened despot who laid the foundations of modern Europe or, instead, a megalomaniac who wrought greater misery than any man before the coming of Hitler." Many historians have concluded that he had grandiose foreign policy ambitions. The Continental powers as late as 1808 were willing to give him nearly all of his remarkable gains and titles, but some scholars maintain he was overly aggressive and pushed for too much, until his empire collapsed.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How have many historians described Napoleon's foreign policy ambitions?
Ah, so.. grandiose

From 1988 to 1997, the BBC and Sky Sports had coverage of the FA Cup, the BBC had highlights on Match of the Day and usually one match per round while Sky had the same deal. From 1997 to 2001, ITV and Sky shared live coverage with both having two matches per round and BBC continuing with highlights on Match of the Day. From 2002 to 2008, BBC and Sky again shared coverage with BBC having two or three matches per round and Sky having one or two. From 200809 to 201314, FA Cup matches are shown live by ITV across England and Wales, with UTV broadcasting to Northern Ireland but STV refusing to show them. ITV shows 16 FA Cup games per season, including the first pick of live matches from each of the first to sixth rounds of the competition, plus one semi-final exclusively live. The final is also shown live on ITV. Under the same 2008 contract, Setanta Sports showed three games and one replay in each round from round three to five, two quarter-finals, one semi-final and the final. The channel also broadcast ITV's matches exclusively to Scotland, after the ITV franchise holder in Scotland, STV, decided not to broadcast FA Cup games. Setanta entered administration in June 2009 and as a result the FA terminated Setanta's deal to broadcast FA-sanctioned competitions and England internationals. As a result of Setanta going out of business ITV showed the competition exclusively in the 200910 season with between three and four matches per round, all quarter finals, semi-finals and final live as the FA could not find a pay TV broadcaster in time. ESPN bought the competition for the 201011 to 201213 season and during this time Rebecca Lowe became the first woman to host the FA Cup Final in the UK.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What network has never refused to show a match?
Ah, so..
unanswerable
