Should i complain to microsoft ?

The other day my teacher asked me what is the structure of the earth? i said , the earth is shaped like a sphere and is slightly squashed at the poles . The inside of the earth is heated for radioactive elements . The earth has a solid outer crust and a solid mantle and a liquid outer core and a solid inner core . We live on the continental crust and the seafloor is called the oceanic crust the oldest rocks found on earth are about 4000 million years old which means the earth has to be older than this the structure of the earth is continuously chaining , rocks are being weathered(broken down) all the time erosion is when the broken bits of rock are carried by water eventually sedimentation takes place forming new rocks . The problem is my teacher said well done and only gave me four stickers instead of five which I really wanted should i complain to microsoft?
