Consider the following statements when answering this question: I. Waiting lists for kidney transplants have been caused by a 1984 congressional law forbidding humans to sell their kidneys.
II) Randomly choosing citizens to serve on juries is an efficient mechanism for selecting jurors.

A) I and II are true.
B) I is true, and II is false.
C) I is false, and II is true.
D) I and II are false.

Statement I is true. In 1984, the National Organ Transplantation Act was passed, which made it illegal to buy and sell organs in the United States. This means that organs, including kidneys, must be donated. As a result, there is a shortage of kidneys available for transplantation, leading to waiting lists. Statement II is false, as randomly choosing citizens for jury duty is not always an efficient mechanism for selecting jurors. It can lead to bias and exclude groups of people who may be less likely to be selected through random selection. Other methods of selecting jurors, such as using voter registration lists or driver's license records, may be more efficient and effective.
