Q: Article: London Heathrow is the biggest airport in the UK, and it also handles more international passenger traffic than any other airport in the world. For this reason, enlargement was planned and on 27th March a fifth terminal opened to help to deal with the many passengers that pass through the airport. The new terminal has taken a long time to plan and build. The idea was first proposed back in the 1980s. The opening of it has been talked about widely in the media in the UK and expectations were high for the PS4.3 billion project. However, in spite of long preparations at Terminal 5 ahead of the grand opening, things soon went into a mess. There were problems from the very beginning as staff had difficulties finding car parking spaces and getting through security to get into the building. This consequently caused a delay when passengers started to arrive and large numbers of staff were not in place. Long passenger queues formed and the slow start meant that everyone had to play catch-up from the beginning. Staffs were having problems using the new systems and a baggage operator told the BBC, it was all "shambles the moment the doors opened". The terminal has been designed to handle 12,000 bags an hour but due to a reported "lack of training and essential support that was promised", a backlog of luggage soon appeared. By lunchtime on that first day, 20 flights had been cancelled to try to alleviate the problems. Flights continued to be cancelled in the days following the opening and up to 28,000 bags have now had to be placed in temporary storage. The British Airline, the only airline operating at Terminal 5 says it is working to clear the backlog, but the negative publicity caused by the shambles has not helped the airport or the airline's reputation at all.
Answer: They had to wait a long time and play catch-up when checking in.

A: What was the difficulty that passengers met with on the very first day of the opening?

Q: Article: TUVALU, a tiny country in the Pacific Ocean, has asked for help as it will be swallowed up by the sea. Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five meters above sea level.Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetables.Without urgent help, the country's days are numbered. But Tuvalu is not the first place to face sinking into the sea.Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years.Experts say that it will have sunk another 20-50cm by 2050.A century ago, St.Mark's Square, the lowest point city, flooded about nine times a year.Nowadays, it happens more than 100 times.While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu's rising sea level. The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 1-3 degrees over the next 100 years. Warmer weather makes glaciers melt, and adds more water to the ocean.The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise.The sea level has risen about 10-25 cm in the last 100 years. The main cause of global warming is human pollution.Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2.This adds to the power of the greenhouse effect, making the planet even warmer. Many scientists believe that, if the warming is not stopped, there will be huge climate changes.The sea level could rise by one meter this century. Should this come true, the sea would swallow up millions of homes and the world will be flooded with "climate refugees" looking for somewhere to live.
Answer: Rare animals moving from place to place for climate changes.

A:
What does "climate refugees" mean?
