Question

the illustration shows rock layers from 3 different locations. which conclusion can be drawn from the picture?location 1auritimidaeremopleiridaeceratopigidaecyclopygidaelocation 2auritimidaeceratopigidaelocation 3ceratopigidaecyclopygidaeasaphidaethe trilobite cyclopygidae appeared most recently of those shown here.the trilobite ceratopigidae appeared before all the others.the trilobite remopleiridae is the oldest of all the trilobites.the trilobite asaphidae appeared most recently of those shown here.

Explanation:

Using the principle of superposition (oldest rock layers are at the bottom, youngest at the top) across all three locations:

1. Auritimidae is at the bottom (oldest) in Location 1 and 2, so it is the oldest trilobite group here, eliminating options about Ceratopigidae or Remopleiridae being the oldest.
2. Cyclopygidae is at the top (youngest) in Location 1 and 3, while Asaphidae is only at the top in Location 3. Comparing all groups, Cyclopygidae appears in the uppermost layers across multiple locations, meaning it is the most recently appearing group.

Answer:

The trilobite Cyclopygidae appeared most recently of those shown here.
