When Louise Meyer was five years old, her mother took her to a science museum. That day, young Louise encountered her first snakes, and she's been fascinated with the reptiles ever since. Meyer now breeds snakes for educational programs. She takes her slinky friends to schools, malls, museums, and special events. She teaches onlookers why snakes are important and describes how to handle them and how to distinguish between poisonous and nonpoisonous species. Wherever Louise sets up an exhibit, curious crowds gather. An effective summary of this entire passage would describe

a how a girl became interested in snakes.
b a woman with an unusual job working with snakes.
c how important it is to understand and appreciate snakes.
d the variety of places where snakes can be found in today's cities.
