CTSS was one of the earliest time-sharing operating systems, developed on the IBM 7094 computer at MIT in 1961. It allowed multiple users to simultaneously use the system via teletype terminals. Key features included virtual memory management, protection of user memory spaces, and a preemptive multilevel scheduling algorithm. It also introduced several pioneering applications like the first email system and text editors. The success of CTSS demonstrated the viability of time-sharing as a paradigm for computer usage.
The city of X was attacked by a natural disaster in 2033, destroying the city. As the mayor, the speaker must rebuild the city and plans for the new city include designating zones for agriculture, residential, industrial, business, educational, government, commercial, port, sources, recreational, community, and service stations to provide for the needs of citizens.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.

Lee Han Lin conducted a site exploration for a proposed eco resort. Data was collected through site observing, pictures, and research. Two organisms found on site - Mint Plant and Garden Skink - were documented in detail. Mint plants grow well in sun or shade with moist soil, reaching 2-3 feet tall. Garden Skinks hunt insects and fruits, living in loose soil and mulch, and lay 2-6 small white eggs. Through their 5 senses, Lee experienced the beautiful rural scenery, birdsong, tasteless water, fresh air smells, and feelings of peace. An ecosystem diagram showed climate influences population growth. Participants had fun getting wet during a mock meeting.
