The stars can only be seen at night.

Absolute or Qualified?

The correct answer is:

Absolute

Explanation:

It is possible to establish this statement as absolute, since absolute statements are sentences that express or reaffirm a specific kind of information without letting space to have any modifier for the given information. e. g. "The stars can only be seen at night."

On the other hand, it is probable to find qualified statements that normally include words that qualify or suggest something about the given information in the statement. e. g. "Sometimes, it is possible to see the stars at night"
