The diagram below represents several sedimentary layers of Earth’s crust after erosion from a river has exposed some of the lower layers. 
Which would be the most significant benefit to a scientist studying Earth’s past at this location?

• Scientists would be able to determine that volcanic activity was present during the time of the oldest exposed sediment layer.

• Scientists would be able to determine if the rocks were metamorphic or igneous.

• Scientists would be able to determine if there was water at this location.

• Scientists would be able to look at fossilized remains of past life dating back to the oldest exposed layer of sediment.

The diagram below shows a stack of rock layers.  
Layer R contains a well-known index fossil that is 100 million years old. Based on this information and the law of superposition, you can make the following claim.

• Layers T and M are younger than 100 million years.Layers X and G are older than 100 million years.

• Layers T, M, X, and G are all younger than 100 million years.

• Layers T, M, X, and G are all older than 100 million years.

• Layers T and M are older than 100 million years.Layers X and G are younger than 100 million years.
