Self-study
Wood that is waterlogged or desiccated can be preserved for a significant period, but, under normal conditions, wood usually disintegrates within a century or two. ███ ████ ███████ ██████████████ ████ ████ ██████ ██ ████ ████ ███████ ██ █████ ███████ ████████ ██ ████████ ████████ ██████████████ ████ █████ █████ ███████ ██████ ██ ███████ ████████ ████ ██ █████████████ ███ ████ ████ ██ █████ █████ █████████ █████ █████ ██████ ████ ████ ████ ████ ███████████ ██ ██████████████ ████ ███ ████████ ███████████ ███ ████ ████████ █████████ █████ ███████ ████████ ███ ████ ████ █████ ███████
Summary
Wood normally disintegrates within a century or two, although wood lasts significantly longer if it is waterlogged or desiccated. For this reason, archaeologists have not found many remains of early wheeled vehicles. However, archaeologists have found small ceramic models of wheeled vehicles made around the same time as early vehicles. These ceramic models have served as the main evidence for early wheeled vehicles because they are less susceptible to disintegration.
Strongly Supported Conclusions
Early wheeled vehicles tended to be made of wood rather than of materials that were not susceptible to disintegration.

This answer is unsupported. We don’t know anything about who made the early wheeled vehicles or the ceramic models.

This answer is unsupported. We don’t know if few models were wooden. We only know archaeologists found ceramic models. It is possible that many models were made from wood, and just disintegrated. We can't assume something about all models based only on the models archaeologists found.

This answer is unsupported. We don’t know from the stimulus which artifacts are more difficult to find. We can't assume that waterlogged or dessicated wooden vehicles exist but weren't found—we just don't know one way or the other.

This answer is strongly supported. The stimulus says that the reason archaeologists haven't found many vehicles is because wood disintegrates over time. The only way that makes sense is if more early wheeled vehicles were made from wood than from materials like ceramic.
