What does the map tell you about a difference between strategies of the Magyars and the Vikings?

The Magyars preferred to invade without settling.
The Vikings preferred to invade by land.
The Vikings preferred to settle along the coast.
The Magyars preferred to invade by land.

The correct answer is answer D ("Relatively brief").

If we look at unemployment statistics in post-great depression-era as a whole, most categories show an improvement in comparisson to the numbers of the Great Depression, including length of unemployment.

However, this particular statistic has seen various peaks throughout modern U.S. economy's history. That's why saying that now is more brief has to be taken as a relative statement. For example, as noted by the Wall Street Journal in July of 2009 "The average length of unemployment is higher than it’s been since government began tracking the data in 1948".

Hope this helps!
