Reading the passage
We need a question the information actually helps us answer. The final two paragraphs describe rain-triggered debris flows and then use observations of modern dunes to explain the conditions that permit them. By contrast, they don't catalog the ancient mammal species or report a discovery of plant fossils.
Working the answers
- A
We are told that mammal fossils exist, but not what kinds of mammals they represent. Mammals is the category, not an identification of the animals within it.
- B
The three sandstone types are ancient deposits. Nothing tells us which kind is currently forming at the site. The word currently changes the information we would need.
- C
Vegetation is inferred from the conditions needed for clay buildup. That is not a report that fossilized plants have been found. A conclusion about past plant life and a discovery of plant fossils are different forms of evidence.
- D
The author doesn't describe sandstorm-killed skeletons at another site. We shouldn't fill in that missing history just because sandstorms elsewhere sound plausible.
- ECorrect
The third paragraph describes the phenomenon in which heavy rain drenches a dune and triggers an avalanche of sand. The fourth connects the process to observations of modern dunes. Together, those details help answer yes: present-day dunes can undergo sudden, violent, rain-caused sandslides. That known process is what makes the proposed explanation of the ancient remains plausible.
