Why is the majority of earth’s freshwater not readily available for our use?
select one:
a. it is in the atmosphere.
b. it is locked up in glaciers and ice caps.
c. it is in rivers far from major human population centers.
d. it is in the ground.

I would go with A because it is in the atmosphere and cannot be used 

and maybe D because its and under water source aquifer  but groundwater for short  

don't hate me if its wrong

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
