Advantage and disadvantage of pencil

Answer 1

There are a lot of advantages to pencils. They don't dry up like pens, for one. They're also eraseable and allow for shading. Thinking more abstractly, they are a direct reflection of how much work you've done with them—the shorter the pencil (or the inner lead in a mechanical pencil), the more work you've done. There are disadvantages, too. They are in constant need of maintenence (sharpeners, extra pieces of lead, etc.) and tend to smudge as you run your hands across their markings.
