Answer:
external task
Step-by-step explanation:
answer is external task because Depending on the previous / successor dependency, the functions of different subtypes can be added together. When you open one of the subpages in the app, the previous tasks from the other sub-projects are shown next to the local tasks in the project being opened. They appear in different work scenes with different bar / box styles and fonts, e.g. In gray, so that they can be distinguished from native works. These tasks are called external tasks.
