A difference in organizational structure between “Will All the Blue Men End Up in Timbuktu?” by Stefan Lovgren and “How to React to Familiar Faces” by Umberto Eco is that— 1) Lovgren develops his main idea through a thorough historical background, while Eco develops his point through personal stories.
2) Lovgren uses the cause and effect structure, while Eco develops his thesis through narrating different scenarios.
3) Both texts use the problem and solution structure, but Lovgren’s text provides multiple solutions.
4) Lovgren uses the cause and effect structure, while Eco compares and contrasts.
