Two tools are found at different sites. Each was buried shortly after it was made.
Table
| Tool | Age of burial layer / million years | Description |
|---|---|---|
| P | 1.1 | finely shaped on both sides |
| Q | 0.7 | roughly shaped on one side |
Which conclusion is supported?
P is older, so the more refined tool must be more recent
P is younger, so refinement alone cannot give a reliable age
P is younger, so the more refined tool must be more recent
P is older, so refinement alone cannot give a reliable age
