What kinds of conditions would make children want or not want to learn a language spoken by their parents or grandparents?

No, because you are more likely to see volcanic mountains where magma is rising along the mid-ocean ridge spreading to the center.

It should be a because the dilation changes the sides but not angles because in all shapes you have a certain degree number to add up to like for example a triangle is always 180 degrees

Many foreign companies buy/build hotels in areas therefore most of the profit from tourism goes to these companies rather than the local economy or local people. 
also, these foreign companies might only employ foreign workers with experience meaning they receive more pay whereas local people would be employed for low skilled jobs and lower pay. 

thats all i can think hope it : )
