Compressions should be done at a rate of 100 to 120 compressions per minute at a depth of about 1.5 inches for infants, about 2 inches for children and at least 2 inches but no greater than 2.4 inches for adolescents.

Savannas can be found anywhere but must be located in a tropical climate to thrive.
The U.S.A. has a very moderate climate, and for the most part is the same overall. Thus, a savanna wouldn't be able to exist in the U.S.A without the tropical climate, which means all 12 months have temperatures around 64 degrees Fahrenheit, and there are only two seasons: wet and dry.
As opposed to the U.S.A's Moderate Springs, Blazing summers, chilly falls, and cold winters (may fluctuate depending on the state), a savanna wouldn't be able to thrive.
Your answer is D: they exist only in the tropics.
