What changes? Which direction?

a. Hot springs are discovered outside of Golden, Colorado, resulting in the construction of several new ski resorts. The resorts offer many personalized services and require a large staff to accommodate customer needs.

b. The Federal government decides to adopt a new visa policy for guest workers seeking to immigrate to the United States in order to find jobs. As a result, 30% more work visas are given out than had previously been granted. The change is expected to be permanent.

c. A new diet is popularized by health expert Richardo Simmonetz that requires people to eat only fried chicken for six weeks. The popularity of the diet results in more chicken plants being built nationwide to handle the increased demand for chicken.

d. Due to low ticket sales, the Broadway production of the musical Mister Saigon decides to have its main actors double up on roles, train them on stagecraft, and have them sell concessions during the intermission, instead of having individual workers for each of these roles.
