Teresa would like to begin eating healthier and has created a plan of action to help reach that goal. Her study group meets at a fast food restaurant twice a week, and she has asked them to meet at the library instead. Teresa understands that to meet her goal, she needs to:. a. reward herself.
b. create a measureable goal.
c. modify her environment.
d. create a realistic time frame.

The correct answer is c. modify her environment.

Explanation:

As Teresa is preparing herself to eat healthier and has created a plan of action to help reach that goal so meeting with her friends at the fast-food restaurant should be avoided because if she will go to fast food restaurant than there will be chances to eat fast food by her which will obstruct her to reach the goal.

Therefore Teresa knows that she needs to modify her environment from fast-food restaurants to the library so that she can meet her goal by avoiding fast food. Therefore the correct answer is c.  modify her environment.
