Which of the following is an example of an observation? a. how much light is needed for plants to grow taller. b. if the speed of a car increases, then it will require more distance to stop. c. based on evidence gathered, i find that movie ticket sales increase steadily until 10 pm, and then decrease for the remember of the evening. d. the width of the rock is 7.6 cm
