hard · LSAT Logical Reasoning
A historian dates an undated chart by a catalog whose dates were assigned from handwriting similarities to dated charts. The historian then argues that those dated charts are correctly dated because their handwriting matches the undated chart, now treated as securely dated by the catalog.
The historian's reasoning is most vulnerable to criticism because it
- rejects catalog evidence merely because it is not numerical
- assumes that handwriting never changes over a person's lifetime
- treats every chart in the catalog as undated
- infers that two historical charts displaying noticeably different handwriting must have been produced by different authors working in different catalog periods
- uses the catalog-based date to validate the charts that supplied the catalog's dating basis, creating circular support
