Final answer:
The example of bread does not tell the difference between rocks and minerals.
Step-by-step explanation:
Rocks are made of minerals. When you split a rock into very small pieces, the pieces are different from each other. This is because rocks can be a mixture of different kinds of minerals or a mixture of different grains of rocks. On the other hand, when you split a mineral into pieces, you still have pieces of the same mineral. Therefore, the example of bread does not tell the difference between rocks and minerals, as bread is made by mixing different ingredients together, whereas rocks and minerals have different properties and compositions.
