What parts of the region fall within the fertile crescent?

I don't know whether there were some options, but I can tell you what regions fall into the Fertile Crescent (understood as the cradle of human western civilisation):

Egypt
Palestine/Israel
The area in Turkey/Iraq/Syria/Iran and Kuwait between the rivers Euphrates and Tigris.

Dall of the above all of the choices make sense

Humid continental climate is found in the interior of continents between the 30 and 60 degrees latitude, but usually above the 40 degree line.   40 degrees north of the equator means less direct sunlight and therefore less warmth.   this climate is mainly found in the northern hemisphere since there are no major landmasses in the southern hemisphere.  if you live in northern indiana, you know all about humid continental because that is the climate type you have!
