Harry, the swimmer with the fastest time on the Springfield College swim team, routinely hyperventilates before a meet, as he says, "to sock some more oxygen into my lungs so I can swim longer without having to breathe." First of all, what basic fact about oxygen loading has Harry forgotten (a lapse leading to false thinking)? Second, how is Harry jeopardizing not only his time but his life?

From the question, Harry seem to have forgotten that It's the CO2 (carbondioxide) level not the O2 (oxygen)level that gives rise to the urge to breathe. That is to say that once the CO2 level in the blood is high, the brain will trigger a breathing response, that will cause the person(Harry) to try to gasp for air. Also, Harry is jeopardizing his time and life because Hyperventilation itself reduces the CO2 concentration of the blood to below normal level, this makes the bloods pH value to raise, this in turn causes the constriction of the blood vessels that supply the brain, and prevents the transportation of certain electrolytes necessary for the function of the nervous system.

The correct explanation to the facts about oxygen loading has Harry forgotten and risking his life is as follows:

Harry has forgotten that It's the CO2 level, and not the O2 level, that causes a person to have the urge to breathe.

once the CO2 level in the blood is high enough, the brain will trigger a breathing response, causing the person to try to gasp for air.
Harry is jeopardizing his time and life as Hyperventilation itself reduces the carbon dioxide concentration of the blood to below its normal level
which causes raising the bloods pH value, initiating constriction of the blood vessels
Leads to supply the brain, and preventing the transport of certain electrolytes necessary for the function of the nervous system.

Thus, above given facts tells how life of Harry is in risk due to his lack of knowledge abut oxygen.
