You are presented with the question "an object will sink in what if it's more dense?" and the following answer choices: 
- water
 - gravity
 - calcite
 - wood
 - liquid
 - rain
 - outer space
 - crust

Now knowing that if an object in a fluid is more dense than that fluid then that object will sink in that fluid because of gravity and water is usually the best fluid, choose the best answer.
