Every day, people are diagnosed with serious medical conditions that lead medical practitioners to infer that they need a new heart, liver, or kidney to survive. The patient is then added to the Organ Procurement and Transplantation Network (OPTN) database, which is used to evaluate which patient on the waitlist is the best match for each donated organ. In addition to medical factors like blood type, the system looks at how far away patients live from the donor. Once organs are removed, they must be transplanted quickly, so the distance to the transplant patient is very important. The heart and lungs, for instance, have to be transplanted within 4-6 hours after removal. Medical technology has improved significantly, so organ transplants are more common and more likely to be successful. However, the number of people on the waitlist for organ transplants still far exceeds the number of organ transplants completed each year.

Option 1:

In 1991, 23,198 people were on the waitlist for an organ. By 2019, this number had grown to 112,568. As the number of people waiting for an organ has grown, the number of organ transplants has also increased. In 2019, a record 39,718 organs were transplanted in the U.S. How many more people were there on the waitlist for an organ than there were organs transplanted in 2019?

A. 70,285

B. 89,370

C. 72,850

D. 702,850

Option 2:

Many people in the U.S. need organ transplants in order to survive, but they are kept on a waitlist because organs are scarce commodities. In December 2020, 108,499 people were waiting for an organ transplant. Of these, 91,752 were waiting for a kidney, while only 3,512 were waiting for a heart.

Approximately what percentage of people waiting for a transplant were waiting for a kidney?

Approximately what percentage of people waiting for a transplant were waiting for a heart?
