The "Donghulin people" site is an early human cultural site in the Neolithic period. The human bone fossils found in the site have been identified as belonging to two adult males and one young female. The neck of the young girl's remains is stringed with small spiral shells. Necklaces and bone bracelets made of beef ribs on the wrists indicate that in the early Neolithic era, human aesthetic consciousness had begun to sprout. Which of the following, if true, would most weaken the judgment? ['Neolithic ornaments are usually stone tools.', 'The unearthed necklace and bone bracelet are very rough.', 'The role of necklaces and bone bracelets is mainly to indicate social status.', 'Two adult male remains have larger necklaces on their necks.']
