<u>Answer:
</u>
Neither rock A nor B could become metamorphic rocks.
<u>Explanation:
</u>
- Magma is the molten rock under the surface hardens into igneous rock. This rock breaks down over time under the process of weathering.
- These pieces of "igneous rocks" are cemented together with other bits of rocks to form sedimentary rocks.
- These rocks get buried under the geological processes like earthquakes. Now, coming in contact with high temperatures and magma, these rocks get changed into metamorphic rocks.
- So, from option A, igneous rock is formed. When combined with rock B and other rocks, sedimentary rocks are formed.
- Metamorphic rocks are formed in the next process. Therefore, neither of the two rocks could become "metamorphic rocks".

Answer:
The correct option is:
This scale rates an earthquake according to how much damage it causes.
Explanation:
The Mercalli Scale was invented by Giuseppe Mercalli in 1902. It is not considered that much of a scientific method to measure to measure strength of an earthquake.
Mercalli scale uses the observation of people who experienced the earthquake, to estimate the intensity. Its measurement is based on how much effect or damage it causes to the humans, objects, buildings, and other man made things.
It is not considered a good way to measure intensity of earthquakes because some witnesses may exaggerate the effects while some may consider it nominal.
