The SAT Reading Comprehension: Basic Principles
In This Article: | |
- The nation's health system requires a continual
supply of new blood from donors to replenish its
stockpiles. Freezing blood for long-term storage is
a delicate, expensive, and time-consuming process;
moreover, many doctors believe that the resulting
product is unreliable. When stored in a solution of
plasma and nutritive dextrose (a sugar), fresh red
blood cells can survive and remain viable for
transfusion for only six weeks.
- Additional facilities must be created to prepare and store blood for future transfusions.
- Without special storage procedures, red blood cells cannot exist for long outside the human body.
- The public should be reminded frequently of the need to donate blood, not merely appealed to in times of crisis.
- The nation's stockpile of blood is dangerously low and needs an immediate infusion of donations.
- The nation's stockpile of blood supplies is exhausted on average once every six weeks.
Don't be discouraged if you found this drill difficult. I designed it to underscore how easy it is to be fooled by the apparent simplicity of even a few words, and to demonstrate why you have to slow down on the questions rather than the passage.
