Suppose Venus were moved to Earth's orbit. Would it still have a runaway greenhouse effect?

  C) No, it is much cooler where the Earth is, so Venus would also cool down and eventually regain its riverbeds.

Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
