Reword the following answer: 1) False. Estimating activity durations is not merely intuitive and subjective; it involves a systematic approach that considers various factors such as resources, work complexity, and historical data. 2) The first step in creating a schedule is **defining the project activities**. This involves identifying all the specific tasks that need to be completed to deliver the project. 3) The four types of activity relationships that can exist between two sequenced activities are: - **Finish to Start (FS)**: The successor activity cannot start until the predecessor activity has finished. - **Start to Start (SS)**: The successor activity cannot start until the predecessor activity has started. - **Finish to Finish (FF)**: The successor activity cannot finish until the predecessor activity has finished. - **Start to Finish (SF)**: The successor activity cannot finish until the predecessor activity has started. 4) Most construction schedules calculate activity durations based on **work estimates and resource availability**. This involves estimating the amount of work or effort required for each task and then considering the availability and productivity of the resources (like labor, equipment, materials) assigned to perform the tasks. 5) An individual work item or task that must be completed in order to finish a project is known as an **activity**. Activities are the smallest unit of work that can be scheduled and controlled in a project. 6) **Activity lag** is the delay between the finish of a predecessor activity and the start of a succ
