The first thing I’d like to say is that course providers do not expect you to know the answer to everything in the initial tasks. You are not expected to know everything; if you did, there would be no point in you following the course! Generally, the objective is to get a feeling of whether you are a suitable candidate to be registered on the course. I would advise you to think about your own experience of learning and examples of teachers who have inspired you.
I can’t say much more than that because I don’t know exactly what the tasks are. In any case, I couldn’t give you more assistance because we don’t answer assignment questions in the forums.
I’m sure that you will answer the questions adequately: your written English is good. I’m sure you’ll do a good job!
