Final answer:
The Expressionist group The Bridge did not rely most heavily on the lessons of Paul Cézanne; they were more inclined toward conveying emotions and inner feelings through bold colors and exaggerated images, unlike Cézanne's structured approach.
Step-by-step explanation:
The assertion that The Bridge group relied most heavily on the lessons of Paul Cézanne is false. While Cézanne, known for his Post-Impressionist works, did have a significant impact on later movements such as Cubism, it was not the primary influence for the Expressionist group Die Brücke. The Expressionists were more focused on conveying emotional experiences and inner feelings through their art, utilizing bold colors and unusual forms. The artists within Die Brücke aimed to express these through exaggerated and expressive images, which is quite distinct from Cézanne's more structured and analytical approach to depicting nature and form with color. Therefore, the answer to the question is b. False.
