Will you please clarify? Why is the format for lettered directions different on pg.10-23 (sample 10-3 shows the lettered direction in 1-5 with subdivisions) and pg. 18-18 (sample 18-2 shows the lettered direction in 1-7 with subdivisions). Thank you.
The indention of exercise materials is based on a combination of 10.4.2 which gives the levels of indention and 10.7 which discusses displayed material. In Sample 1-3 the displayed material should have begun in cell 5. In Sample 18-2 there are three layers of information which dictates the use of cell 1-7 for the lettered component, cell 3-7 for the numbered component, and cell 5-7 for the component with lower case numbers.
