Answer the following statement(s) true (T) or false (F)

1. Where circular runout is applied to a cylindrical surface, the tolerance zone is two coaxial circles centered on the datum axis.
2. When establishing a datum axis, where the surface is the primary datum feature, the diameter should be long.
3. Where circular runout is applied to circular elements constructed around a datum axis, it limits the deviations in circularity, orientation, and axis offset (location).
4. In certain applications, the function of a part requires defining the total runout deviation of a diameter relative to a datum axis. In this application, the tolerance value defines the radial distance between the tolerance zone cylinders.
5. In certain applications, the function of a part requires defining the circular runout deviation of a planar surface perpendicular to a datum axis. Where circular runout is applied to a planar surface, The tolerance zone limits deviations in form, orientation, and location of the circular element.
