The evolution of the eohippus into the modern day horse is an example of metamorphosis.
A character change would be internal, stasis means to remain the same and extinction is the end of an organism, the eohippus is extinct, but the question is asking specifically about it's change. Therefore choice 4 is the correct answer.
People believe that being a man means you need to have a deep voice,beard,and spread you legs when you sit to take up space, but being a man actually means being yourself and not letting anyone tear you down. Being a REAL man means to be kind and show the world that you are not going to let anyone tear you down.
Does that answer your question?
Animal Farm was published on the heels of World War II, in England in 1945 and in the United States in 1946. George Orwell wrote the book during the war as a cautionary fable in order to expose the seriousness of the dangers posed by Stalinism and totalitarian government.
hope this helped :)
