across messages with some of the words highlighted with an interrupted line. In this case, part of you assignment is to determine whether these words are required for a successful task completion. You will find the tags Required/Not Required for Successful Task Completion at the bottom of the list of tags on your right.
A rule of thumb is to assign each word only one tag.
Therefore, first you have to tag the words that definitely have the corresponding tags. If you still see any more highlighted words, tag those that are definitely of no importance to the task completion with “Not Required”. See if any of the remaining words are relevant and annotate them with “Required”.
