Analogies evaluation, how do they work?

Think more about how analogies look and how they work.  The purpose of the prompt is to get you thinking about how we form comparisons (analogies) and the mistakes that are commonly made in doing so.  Below are three analogies – analyze them for form, and then evaluate their strength.

1.  Astrology studies the stars and has been around for hundreds of years.  Astronomy also studies the stars and has been around for hundreds of years.  We know astronomy is worthy of being called a science.  Therefore, astrology is also worthy of being called a science.
           a.  analyze the form of the analogy
            b.  evaluate the analogy
Just as  the leader of an athletic team must have a management style that facilitates the group working together, so too  the manager of a business must be able to help his or her employees to work well together. This is because  a manager of a business is like an athletic team coach given that  each has to work well with people of all different backgrounds and personalities.
           a.  analyze the form of the analogy
            b.  evaluate the analogy
2.  Plants are a lot like animals, because they both transfer energy of one kind to energy of another.  Since most plants get their energy directly or indirectly from sunlight, animals, too, must get their energy from sunlight.
          a.  analyze the form of the analogy
            b.  evaluate the analogy
