Cathy just bought a hang glider. Which of these could have been an internal factor that influenced Cathy's decision?
A. Cathy just loves the way hang gliders float through the air.
B. Everyone else who lives on Cathy's block has a hang glider.
C. Cathy recently read an article in a magazine about hang gliders.
D. Cathy just saw a movie in which the star flew with a hang glider
Internal factors are things such as needs, motives, and perceptions, while external factors include things such as family, friends, or social media. Options B, C, and D are external factors because the decision to buy would be based on the people on her block, a magazine article, or a movie. Only option A is based on Cathy's own perception.
