The answer is 2. The fact that mechanized agriculture has replaced manual labor. Hope this helps :)
It has increased by 1.4 fahrenheit
I’m not sure why you’re having trouble with this simple question.. but I’ll help.
All you have to do is add both degrees to each other if they’re on the opposite side of the equator. (0 degrees)
And if they’re on the same side of the equator subtract the smaller number from the bigger number.
So the answers in order should be
120 degrees
130 degrees
30 degrees
Hopefully this helps!
