I'm interested in understanding the types of historical content available on California Revealed. Can you tell me what the first three main historical themes are, as categorized on their website, and provide a brief description of what each theme covers?
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.
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.
