Read the following scenario and answer the question(s) below.
the formation of sinkholes has become a fairly common phenomenon in the state of florida. most sinkholes are small, but some sinkholes have led to catastrophic property damage and loss of life. one september day in 1999, folks began to notice that lake jackson in the panhandle region was shrinking. within a few days, it was almost gone. a sinkhole had opened beneath the lake and drained it, along with all of the fish and alligators. another sinkhole formed just 10 miles from walt disney world in august 2013, swallowing a 48-unit villa at summer bay resort.
as aquifers lose water, their substrates can become weaker and less capable of supporting overlying strata and any human structures built upon them. in such cases, the land surface above may subside. sometimes subsidence can occur locally and suddenly, in the form of sinkholes, areas where the ground gives way with little warning. once the ground subsides, soil becomes compacted, losing the porosity that enabled it to hold water. recharging a depleted aquifer may therefore become more difficult.
one reasonable way to prevent sinkholes might be to

in addition to spreading humanist ideas, erasmus has contributed to criticism of corruption in the church.

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.  

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
