Answer to Question 1

Answer: D

Answer to Question 2

Answer: When elements near iron, or iron itself is fused, energy is absorbed by the fusion reaction instead of released. This cools rather than heats the star, and the show is over. The star then undergoes collapse without rekindling. The most massive of these stars may supernova.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
