**Question 11**

Based on rock type, which paleoenvironment did *Pseudoatrypa devonica* live in?  
- ○ clean, clear water, fast-moving currents or waves, and hard, sandy substrates.
- ○ turbid water, little current activity, and soft, muddy substrates.

**Question 12**

![Image of three brachiopod shells with labels: Pseudoatrypa devonica, Spinatrypa spinosa, Tropidoleptus carinatus](image)

**Explanation of Image**:  
The image depicts three different types of brachiopod shells, each labeled with its scientific name:  
- On the left is *Pseudoatrypa devonica*, which has a larger, more rounded shell.  
- In the middle is *Spinatrypa spinosa*, showing a smaller, elongated shell.  
- On the right is *Tropidoleptus carinatus*, featuring a small, compact shell.

**Question 12 Continued**

Why would a larger, more rounded shell develop in the lineage of this brachiopod?  
- ○ To prevent its feeding filter from clogging
- ○ To protect itself from predatory attack
- ○ To secure itself in an environment with fast moving currents

### Question 9

"The _______ interval is the time difference between the arrival of the primary and secondary waves, this is then used to calculate the distance from the seismograph to the earthquake."

- P - S
- S - P
- I K G
- Seismic

### Question 10

"On the circle that is drawn using the distance calculated from the difference of the arrival of primary and secondary waves, gives you the __________ of the circle."

- circumference
- area
- radius
- diameter

These questions focus on understanding the principles of seismology related to the time interval between seismic waves and how they aid in calculating distances relative to earthquake activity.
