Hello, I believe its because of didnt want the money the work offered. He did the job for satisfaction and not for money.
I would say a hero is someone who stands out from the crowd and exceeds expectations to change the world. A hero is someone who perseveres to help society. During these dark days, for sure, all nurses, doctors, paramedics, firefighters are defined as heroes. They fight to save a life. To save a life that is crucial to its surroundings and community. With all their might, these heroes push and push and push the dark door away from the way to hopefully see the light that we are all waiting for.
I believe it is option "D.) The flu vaccine is not reliable enough to be worthwhile"
It would have a negative impact on the economy due to people not spending money to have the flu vaccine.
