Exam PRINCE2 Agile Practitioner topic 1 question 21 discussion

Project scenario - Get fit with football!
(Note: The companies and people within the scenario are fictional)

Introduction -
A Local Government Authority (LGA) has decided to organize a six-a-side football tournament. The tournament will contribute towards achieving the targets set by a national initiative to improve the fitness of children under the age of 16. As part of the LGA's policy of self-funding, this has to be achieved at zero cost to the LGA (and therefore the local tax payer). The cost of the event will be covered through fees paid by teams registered to take part in the tournament, sponsorship and monies raised during the day. Any surplus would be used for the maintenance of local sports centres.
Teams can register under one of several age groups for both boys and girls. In addition, family members are asked to attend to provide support.
This sports event is designed to be a family day out. The football tournament will have an event village including a kidz'-zone, catering, car parking, mobile changing rooms and toilets. The tournament will take place on the LGA-owned football pitches near the centre of the town, although space is somewhat limited.

Scope -
The initial scope of the project includes:
a marketing campaign to promote the event;
a celebrity to open the event;
a website to provide information about the event and handle applications; an event village to support the 'family day out'; the training of LGA staff as volunteers to run and support the event; back-office processes to handle the applications; fundraising to cover the cost of the event.
The project has been set up with four work streams to deliver this work:
1. Marketing
2. Website
3. Event Village
4. Staff Training

Project Background -
The LGA have extensive experience in using PRINCE2 and will run the event as a single project. The project manager is fully conversant with PRINCE2 Agile. One office in the LGA building in the centre of town has been given to the project for the entire duration. The office is across the corridor from the Marketing Department and the project manager has already put a sign on the door that says 'Mission Control'.

Timeline -
An initial timeline has been suggested and is shown in the following diagram. The timeline may evolve due to the agile ways of working. The timeline shows how work streams are broken down into work packages and/or timeboxes.

Website - Additional information
A new website will be built for the event. There are five work packages within this product:
1. Initial homepage:
Website showing the event details, competition rules, etc.
2. Team Registration functionality:
team name, player's names and ages;
contact information;
payment;
lunch pack requirements (includes any special dietary needs); car parking requirements.
3. Social media promoting the event and its aims.
4. Applications (apps) to promote healthy lifestyles including fitness and healthy eating apps.
5. Health Park:
An online knowledge base about healthy lifestyles that includes a discussion forum.
The Website Team have a lot of experience in IT and have been using agile for several years. They are delivering the website through five two-week timeboxes. The team uses a Scrum Master to facilitate and the Scrum process and coach people accordingly.
The Website Team are very good at Scrum. They have created a set of tasks to assess more difficult work and they refer to this as sprint zero.
Using the Project Scenario and Website Additional information, answer the following question:
The Scrum Master has been advised by the supplier subject matter expert that the five day task of building the social media website is now almost complete - there is just one more day's work to do.
How should this be shown on the burn-down chart?
