Any ideas for a solar cooker? any info or instruction would be greatly appreciated!

I learned that you can bake anything in the sun with these instructions:

If you get a pizza box, put aluminum foil inside so the light of the sun reflects off of it and hits the food inside. So no bugs or anything gets into the food, put a sheet of plastic over it and make sure the sun is shining bright and hot so your food gets warm :) hope this helps I only got it from TV

it is either c or d and i know for sure it is not a or b

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
