Question 2
When Angel was walking down the dark alley, a dog came out and started to growl at him. However, it was too dark for him to see the dog clearly. What would have helped Angel in this situation?
◦ He should have looked directly at the dog, to activate his cones so he could see it more clearly.
◦ Since it was dark, he should have looked slightly off to the side of the dog so his rods could help him see.
◦ It would have been best for him to blink several times so his eyes could bring in more light.
◦ He should have closed his eyes and relied on his hearing to avoid the dog.
