In the 1800s, every county in the United States may have boasted its own farrier. Now, if someone wants to own a horse, they must search hard for a farrier who will be able to shoe and maintain the horse’s hooves. Which statement BEST explains the reason that farriers are less available today than they were in the past?
A.
Technology has advanced to where much of a farrier’s duties can be done by owners themselves.
B.
When horses and buggies were replaced by automobiles, less people needed the services of farriers.
C.
Veterinary scientists have found that the methods used by farriers, such as nailing horseshoes on, cause more harm than good to a horse.
D.
The work is hard because of the heat and danger involved and fewer people are interested in pursuing such a career.
