Answer: the birth of Arabian civilization can be dated to 7th century A.D. Then Islam was spreading westwards to northern Africa...from Egypt to Maroccos. From Maroccos Muslims spread to Iberian peninsula. But they were not able to move more northwards ....beyond Pyrenees. Christian states were stable, well-organized and were able to organize their armies and protect themselves.
Explanation: they were not able to move beyond Pyrenees because already in the north of Iberian peninsula there were well-organized Christian kingdom. They were small but they constituted a barrier. The only significan Arabian invasion to Europe consitutes "battle of Poitiers" (sometimes called "battle of Tours) in 732 A.D. There Franks led by Charles Martel were victorious and Arabians had to retreat behind Pyrenees. Later on Arabians were expulsed from Iberian peninsula (first from Portugal, then from Spain).
Those are all plateaus, though you could figure this out with elimination, too. Peninsulas are land forms with 3 sides water, mountains generally form in mountain ranges, and usually deserts are larger than the two small cells on the right side.
