TASK DEFINITION: In this task, you are given an article. Your task is to summarize the article in a sentence.
PROBLEM: The event is part of an art exhibition at the 20-21 Visual Arts Centre, which began on Saturday 18 February.
To find and keep the pieces, worth at least Â£1,000 each, people must study five paintings and solve the code within them.
One of the items was found by accident so a reward is being offered to anyone who can solve the clue linked to it.
Artist Luke Jerram said he would donate Â£500 to a charity of the finder's choice if they could solve the mystery of the "red picture".
The fourth item, the golden train, was found by a family from Grimsby in Scunthorpe's Central Park on Friday night.
Mr Jerram said he had not anticipated so many items would be discovered in the first week.
"I was expecting two or three, something like that. What I did not expect was the response of the public would be so astonishingly positive.
"I did not expect the public would go round looking in every nook and cranny of the town to try and find the artefacts."
The Visual Arts Centre said the public response had been extraordinary.
"It has created a real buzz around the place and brought in thousands of people," said the centre's visual arts officer Michelle Lally.
The final item to be found is the gold copy of a Jurassic ammonite, an ancient marine mollusc fossil.
The five objects are replicas of pieces at North Lincolnshire Museum and were made from gold worth Â£1,000, but could be worth much more.

SOLUTION: Four of five gold artefacts hidden in Scunthorpe as part of a treasure hunt have been found inside a week.

PROBLEM: The British Pregnancy Advisory Service service said it will offer advice to women concerned about any symptoms they have after taking the illegal pills.
However, anti-abortion campaigners have said the helpline is a "publicity stunt".
The law surrounding abortion in Northern Ireland is much stricter than in the rest of the UK.
A woman can have an abortion, but only in very specific circumstances.
It is only permitted if a woman's life is at risk or there is a permanent or serious risk to her mental or physical health.
Taking drugs to bring on a miscarriage without doctors' consent is an offence anywhere in the UK under the 1861 Offences Against the Person Act.
The British Pregnancy Advisory Service (BPAS) said that while adverse events were "extremely unlikely", some women may not seek help from a doctor when they need it because they are committing a criminal offence.
The service will also be available in the Republic of Ireland and the Isle of Man.
Ann Furedi, chief executive of the BPAS, said: "What these women really need are accessible, high-quality abortion services at home.
"They shouldn't have to make the choice between travelling to England and breaking the law by purchasing pills online.
"While we wait for politicians to do the right thing, BPAS will provide telephone aftercare to women who have bought pills online and who want to speak to someone in confidence about what they are experiencing, or who simply need a reassuring voice at the end of the line.
"We will be here for these women 24 hours a day until they no longer need us."
'Publicity stunt'
However, Marion Woods of the anti-abortion group, Life NI, told the BBC's Good Morning Ulster that the helpline was "a publicity stunt".
She said support for women needing help should be provided "within the framework of our law".
Mrs Woods said a newspaper advertisement issued by BPAS "challenges our government, challenges our law".
"How safe are these pills in the first place?" she added.
Dawn McAvoy, spokeswoman for the Evangelical Alliance, said women needed support.
"Groups need to work together to provide the best possible care for women and children within the current law, because both lives matter," she said.
"We want Northern Ireland to continue to value the life and health of the woman and the unborn child, advancing the wellbeing of both because both lives matter."
Breedagh Hughes, Northern Ireland director of the Royal College of Midwives (RCM) said "anything that helps women that find themselves in a very distressing situation can only be helpful".
She said the RCM was "quite clear that they should not be obtaining pills online, that we would much prefer that this was a prescribed medication given under medical direction".
Ms Hughes said they feared that "we may begin to see over the next few years women begin to die again from botched abortions.
"It's a backstreet abortion using another method. It's not coat hangers anymore, it's pills bought online".
In a statement, the Police Service of Northern Ireland said it "would like to take this opportunity to remind members of the public not to take any prescription drugs that have not been prescribed to them.
"The taking of any prescription drug is potentially very harmful and can result in developing serious complications if used without the appropriate medical supervision".

SOLUTION: A telephone helpline has been set up in Northern Ireland for women who have bought so-called abortion pills online.

PROBLEM: About 80% of teenagers questioned also believed they were more engaged with social issues than their predecessors.
The think tank, Demos, which commissioned the survey, said the findings "shatter misconceptions of disengaged teenagers".
More than 1,000 14-17-year-olds from England and Northern Ireland took part.
Demos said false stereotyping of young people in the media and wider society was having a negative effect on both their self-esteem and employment opportunities.
It said four in five teens felt they were unfairly represented in the media and, of these a vast majority - 85% - said this was affecting their chances of getting a job.
Demos said its survey tested "attitudes and perceptions" of teenagers. It did not investigate the views of employers.
It said it had also analysed six UK newspapers over the past 10 years and found that the words most commonly associated with "teenagers", "youth" and "young people" were "binge-drinking", "yobs" and "crime".
Last month, McKinsey management consultants reached a different conclusion, blaming high levels of youth unemployment across Europe on a skills shortage rather than a lack of jobs or any reluctance to employ young people.
It said 27% of employers had left "entry-level" jobs unfilled because they could not find people with the necessary skills.
The European commissioner for education and youth, Androulla Vassiliou, said there was a mismatch between what education systems were delivering and what employers needed.
Becky Brunskill, 18, member of Youth Parliament for Liverpool, says:
"At the moment, teenagers feel like they're in the minority really. They are always the ones to get bad press. The young people out there are doing good things for the community, but there's always the stabbing, the hoodie or gun crime that's always on the news. But we're not all like that, it's only a few.
"We need to show businesses and the media that young people are passionate and want to get involved and make a change. There is always negative press. You see on the news, say five times out of the seven days that it's on there's a bad story about young people, so maybe they're a bit put off because maybe they think we'll bring trouble to their business. But we won't.
"Working for the National Citizen Service, the Youth Parliament and the British Youth Council, I'm a much more confident person and I want to go into a business and give them my skills that I've got."
In a recent opinion piece, City & Guilds Group chief executive Chris Jones gave a similar assessment, saying most employers believed young people did not understand what businesses were looking for.
Asked if youth unemployment was down to structural change in the labour market and a skills shortage rather than negative portrayals in the media, the author of the Demos report, Jonathan Birdwell, said: "Those are absolutely valid points and important factors to consider.
"But there is this perception that they [teenagers] are negatively portrayed. Those messages have an impact on how they perceive their job opportunities.
"The fact that these perceptions are so widespread among young people has to have an impact."
Bob Satchwell, executive director of the Society of Editors, said young people "should remember that news media generally reports bad news because bad news is the unusual stuff".
He said if teenagers looked at media coverage more widely they would see "a much more balanced picture" with prominent positive reporting of high-achieving young people including A-level students, Olympic athletes and footballers, as well as young soldiers who had served the UK abroad.
The Demos survey also asked teenagers about social issues and found that 80% of those asked believed they were more concerned with social issues than previous generations of young people.

In a parallel survey for Demos by SchoolZone, two thirds of UK teachers agreed that teenagers today were more socially engaged than their own generations had been.
But the survey suggested social engagement did not translate into direct political engagement.
Only 10% of teens questioned saw politicians as agents of positive change, while 60% said they saw charities and social enterprises in that way.
"Teenagers are motivated to make a difference in their community but the approach they take is radically different to previous generations," said Mr Birdwell.
In the survey, 87% of teenagers said social media was an effective way to give momentum to social issues.
Mr Birdwell said: "They do not rely on politicians and others to solve the world's problems, but instead roll up their sleeves and power up their laptop and smartphone to get things done through crowd-sourced collaboration.
"They value bottom-up social action over top-down politics, and social enterprise over government bureaucracy.
"The next generation could be the most active citizens we have seen in a generation."

SOLUTION:
More than two thirds of 14-17-year-olds believe negative portrayals of teenagers in the media are affecting their job prospects, a survey suggests.
