Despite previous technical issues, explore CliffsNotes.com to determine the full range of academic subjects covered by its study guides beyond just literature. Specifically, identify at least three distinct subject categories other than 'Literature Notes' (e.g., History, Math, Science, Social Sciences, etc.). If the 'Study Guides' link continues to be blocked, try to navigate through 'Lit Notes' or other available links to find subject categories.
Navigate to 'https://www.cliffsnotes.com/'. Attempt to click on the 'Study Guides' link (ID 15) to access the main study guide directory. If the 'Study Guides' link fails due to an Incapsula error, attempt to click on the 'Lit Notes' link (ID 14) as an alternative entry point. From whichever page successfully loads (Study Guides or Lit Notes), look for a navigation menu, sidebar, or section that lists various academic subjects. Identify and list at least three distinct subject categories for study guides that are not 'Literature' or 'Lit Notes'. If only literature categories are visible, identify at least three different literary sub-genres or authors if broad subjects are not available.
The agent successfully navigates beyond the homepage to a page listing study guide categories. The agent identifies and states at least three distinct academic subject categories for study guides (e.g., 'History', 'Math', 'Science', 'Social Sciences', 'AP Exams', 'ACT', 'SAT'), or if only literature is accessible, three distinct literary sub-genres or authors (e.g., 'Shakespeare', 'American Literature', 'Poetry'). The agent clearly states the path taken to find these categories (e.g., 'via Study Guides link' or 'via Lit Notes and then navigating sidebar').
