Answer: d. AIDS
Step-by-step explanation:
In the 1980s, AIDS had come to prominence and was running rampant in the United States, ravaging it as well as the rest of the world. Thousands died and thousands more were infected. People watched as their loved ones became mere shadows of themselves before they passed on from this life and medical science could not stop it.
Young people have always been at the forefront of social change and innovation and saw AIDS as a challenge that needed to be dealt with quickly and decisively. They therefore tried to help out where they could which led to many joining large non-profits to assist them in raising the millions of dollars required to combat AIDS by finding it's cure.
