Answer 1

The feature of the rock that demonstrates it is a clastic sedimentary rock is **visible rock fragments**. Clastic sedimentary rocks are characterized by the presence of fragments from other rocks and minerals that have been cemented together. In this case, the brown rock containing small pieces of different materials indicates that it includes visible rock fragments, which is a defining characteristic of clastic sedimentary rocks.
