5. READ THIS STORY AND ANSWER THE QUESTIONS:
Jill baked a cake for her mother's birthday. When she removed the cake from the oven,
Jill noticed that the cake had not risen. Jill guessed that the baking powder she had
used was too old. She designed the following experiment to test his idea. Jill prepared
two cakes – one using the same ingredients as her first cake and one using fresh baking
powder. After preheating oven to 350°F, she placed both cakes in the oven for 30
minutes. After 30 minutes, she removed both cakes and noticed that neither one had
risen. She decided that the baking powder wasn’t the cause of his problem.
