In central portions of the U.S., tornadoes are more common than anywhere else on Earth and touch down most commonly in the spring and summer. Deadly and destructive hurricanes occur almost every year along the Atlantic seaboard and the Gulf of Mexico. The Appalachian region and the Midwest experience the worst floods, though virtually no area in the U.S. is immune to flooding. The Southwest has the worst droughts; one is thought to have lasted over 500 years and to have hurt Ancestral Pueblo peoples. The West is affected by large wildfires each year.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Destructive hurricanes occur along the West Coast and where else?
Ah, so.. unanswerable

Race was asked differently in the Census 2000 in several other ways than previously. Most significantly, respondents were given the option of selecting one or more race categories to indicate racial identities. Data show that nearly seven million Americans identified as members of two or more races. Because of these changes, the Census 2000 data on race are not directly comparable with data from the 1990 census or earlier censuses. Use of caution is therefore recommended when interpreting changes in the racial composition of the US population over time.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many American reported being of more than one race in the Census 2000?
Ah, so.. nearly seven million

Beginning in 2005, the CBC has contributed production funds for the BBC Wales revival of Doctor Who, for which it received a special credit at the end of each episode. This arrangement continued until the end of fourth season, broadcast in 2008. The CBC similarly contributed to the first season of the spin-off series, Torchwood. More recently, the network has also begun picking up Canadian rights to some Australian series, including the drama series Janet King and Love Child, and the comedy-drama series Please Like Me.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What year did the CBC begin contributing funds to the show Doctor Who?
Ah, so..
2005
