The following code creates the ten activities masonry, carpentry, plumbing, ceiling, roofing, painting, windows, facade, garden, and moving. The argument dur accesses the durationsDesign array. The third argument, the integer 0 through 9, is the transition type. The transition type is used in the next section to define the transition time.
