Questions and Answers

What is the main purpose of biological classification?

  • To group organisms based on their color
  • To organize organisms based on their size
  • To categorize organisms based on their geographical location
  • To arrange organisms according to their shared traits and evolutionary relationships (correct)

How does the classification of television programs in the example reflect the nature of classification systems?

  • By creating a continuous spectrum of program types
  • By categorizing programs into multiple groups at once
  • By considering all possible categories at once
  • By making a binary decision at each step of the process (correct)

What potential issue might arise when classifying a program like BBC News?

  • It may be too long for any category
  • It may not fit into any category
  • It may have overlapping characteristics (correct)
  • It may not be popular enough for a category
