The primary evidence for an accelerating Universe comes from observations of young stars in the Milky Way.

A.) True, observations show that there were many more young, massive stars in the early Universe. B.) True, massive star supernovae allow us to measure the expansion rate of the Universe. C.) False, in order to measure accelerating expansion, we need to measure the distances of objects billions of light-years away. D.) False, evidence for an accelerating Universe comes from observations of the oldest stars in the Milky Way, white dwarfs. E.) False, we have to look at young stars in other galaxies beyond the Milky Way to measure the acceleration of the Universe.

Joe's toaster broke. He bought a toaster oven to replace it, telling his wife Annie that it is cheaper to make toast in the toaster oven than in the range's oven

Toast takes 5 minutes to cook in the toaster oven while it takes only 3 minutes in the range's oven. Is Joe right or is Annie, who says they've wasted their money? Explain.
