After examining a set of Bronze Age bronze chisels, an archaeologist concluded that they had been used mainly for woodworking, pointing to microscopic wear patterns on their blades that are consistent with cutting wood.

Which finding, if true, would most seriously weaken the archaeologist's conclusion?

  1. Experiments show that cutting bone and antler leaves wear indistinguishable from wear left by cutting wood.
  2. Several of the chisels were found next to wooden objects bearing cut marks that match the chisels' blades.
  3. Bronze was a valuable material in the Bronze Age and was frequently melted down and recast.
  4. No tool used in the Bronze Age is likely to have served only a single purpose.
