I'm exploring California Revealed and want to understand the main historical categories of content available. Can you list the first three historical themes presented on their 'Themes' page and briefly describe what each theme broadly covers based on the information provided?
Navigate to the homepage of californiarevealed.org. Click the 'Discover' button. Click on the 'Themes' link within the 'Discover' sub-menu. On the 'Themes' page, identify the titles of the first three themes. For each of the first three themes, briefly describe its historical focus based on the accompanying information.
Successfully navigates to the 'Themes' page (https://californiarevealed.org/themes/grid). Lists 'Activism: Anti-War' as the first theme and provides a description indicating its focus on historical anti-war movements/activities. Lists 'Activism: Environmental' as the second theme and provides a description indicating its focus on historical environmental protection/advocacy. Lists 'Architecture' as the third theme and provides a description indicating its focus on historical design/construction of buildings.
