What was peculiar about the "pencil lady" during the tests?

The peculiar characteristic of the "pencil lady" during the tests that stands out is her loud eating habits. This behavior was distracting and contrasted sharply with the intense atmosphere of the testing environment. It also helps to highlight her unusual presence and contributes to the overall theme of unexpected and unconventional elements within the story. The other choices may have their own significance but do not carry the same weight in terms of impacting the moment or contributing to the reader's understanding of the tests' environment. The loud eating not only defines her character but also serves to emphasize the quirky and sometimes absurd nature of the events surrounding the tests undertaken by the candidates.
