You have considerable freedom in choosing a topic, with the exception of the topic must apply directly to trans[prtation.

The requirement is that your topic requires academic research not business research and that you submit both your paper topic (which should not contain a question) and a full paragraph statement, that statement must contain a research question to be answered or a hypothesis to be tested. Most "why" questions focus more on workplace related issues and business not academic or scholarly research so they seldom are acceptable questions for scholarly research
