Question

Which conclusion does this diagram BEST support?

A.
The earthquake that caused the fault most likely killed both organisms because the fossils formed during the time of the earthquake.


B.
The fault formed while Organism X was living and after Organism Y had died because the fault is located between the two fossils.


C.
Both organisms lived at the same time because the fossils they formed were found in rock layers of about the same depth.


D.
Organism Y lived before Organism X because Organism Y was found in an older rock layer

To determine which conclusion the diagram best supports, we need to analyze the options based on the provided information about the fossils and the fault.

- **A** suggests the earthquake that caused the fault impacted both organisms. However, without more information about the timing of the fossils relative to the earthquake, we cannot confirm this.

- **B** states that the fault formed while Organism X was living and after Organism Y had died, based on the positioning of the fossils. This is a reasonable conclusion if the diagram shows that the fault is indeed between the two fossils and indicates their relative ages.

- **C** implies that both organisms lived at the same time because they were found in rock layers of similar depth. This would only be true if the fossil layers are contemporaneous, but it doesn’t directly ensure they lived simultaneously.

- **D** claims that Organism Y lived before Organism X because it was found in an older rock layer. This conclusion would depend on the specific arrangement of the rocks and fossils, but is a common interpretation if layers are distinct.

Based on these analyses, the conclusion that best aligns with geological principles and is most supported by the information provided appears to be:

**B. The fault formed while Organism X was living and after Organism Y had died because the fault is located between the two fossils.**

This option directly connects the formation of the fault with the relative timing of the two organisms based on their fossil positions.
