In this task, you will be shown a passage. You need to write a fill-in-the-gap question based on your understanding of the events that might be inferred from the passage. Your question should be answerable based on the passage and only have one correct answer. Show the gap in your question with a _ .
One example: For four years we have waited expectantly for the pitter patter of tiny paws. Soon, that wait could finally be over. Tian Tian, the UK's only female giant panda, has conceived and could give birth to a cub as early as August. However Edinburgh Zoo, where the pandas live, have warned people 'not to get too excited' as the process is 'extremely complex'. Moreover, on the two previous occasions keepers inseminated Tian Tian - whose name means 'Sweetie' - she has failed to produce a panda cub. She was artificially inseminated again in March this year, but keepers at the zoo say implantation - when a fertilised egg attaches to the uterus - has not yet occurred.Tian Tian has conceived and could give birth to a cub as early as August. She has been inseminated twice before but so far failed to produce a cubTian Tian and Yang Guang arrived in 2011 from China to great fanfareOn loan at £600k a year, became first giant pandas to live in UK for 17 years

Explanation: This is a good example. Based on the passage you can answer this question.

Now, solve this: A pair of crooked casino croupiers and their friend pocketed £23,000 after working out a way to fix a roulette wheel. Craig Walker and Daniel Johnson - who worked at Coral Island casino in Blackpool, Lancashire - rigged the wheel so that ball would stay in the same slot and win their friend Kevin Traynor thousands of pounds, which they then split between them. After their scam was uncovered by casino bosses, the three men admitted fraud and the two croupiers have now been jailed. Preston Crown Court heard Walker, 26, and Johnson, 29, were working together on a quiet shift at the casino when they discovered it was possible to perform a 'no spin' on the wheel - fixing it so the ball stayed in the same slot.Two croupiers fixed it so that ball stayed in the same slot on wheelThey signalled to their friend so that he could increase his stakesThe trio were caught when casino boss examined CCTV of tableThree men all admit fraud and the two croupiers have been jailed
