I am a prospective student interested in the academic achievements and research at Merton College. Using the news section's filter functionality, find any news articles related to 'Computer Science' or 'Mathematics'. For the most recent article found in either of these categories, state its title and publication date. If no articles are found in these specific categories, state that and then identify the title and publication date of the oldest news article currently displayed on the main 'News' page.
Navigate to 'https://www.merton.ox.ac.uk/news'. Click on the subject filter dropdown (ID 268). Select 'Computer Science' from the dropdown. Click the 'Apply' button (ID 299). Check if any articles are displayed for 'Computer Science'. If an article is found, state its title and publication date as the most recent. If not, proceed to the next step. Click on the subject filter dropdown (ID 268). Select 'Mathematics' from the dropdown. Click the 'Apply' button (ID 299). Check if any articles are displayed for 'Mathematics'. If an article is found, state its title and publication date as the most recent. If an article was already found for Computer Science, prioritize the most recent of the two. If no articles are found for either, state that no articles were found for these subjects. If no articles were found for 'Computer Science' or 'Mathematics', scroll down the main 'News' page (after clearing any filters if necessary) to identify the title and publication date of the oldest news article displayed.
The agent successfully navigates to the 'News' section. The agent attempts to filter by 'Computer Science' and 'Mathematics'. If an article related to 'Computer Science' or 'Mathematics' is found, the agent states the title and publication date of the most recent one. If no articles are found for 'Computer Science' or 'Mathematics', the agent explicitly states this. If no articles are found for the specified subjects, the agent identifies and states the title and publication date of the oldest news article displayed on the main 'News' page (without filters applied).
