Input: Consider Input: Sentence 1: Anna Nobili is no ordinary nun. The 38-year-old used to be a lap-dancer, and spent many years working in Italian nightclubs. She is now using her talents in a rather different way - for what she calls "The Holy Dance" in a performance on Tuesday evening at the Holy Cross in Jerusalem Basilica in Rome, in front of senior Catholic clerics including Archbishop Gianfranco Ravasi, head of the Vatican's Cultural Department. Miss Nobili told the BBC World Service that the transformation from podium lap dancer to nun happened gradually. Sentence 2: Anna Nobili became a nun in 2002.

Input: Consider Input: Sentence 1: The drive towards this new law was driven in part from a string of transport-related disasters in the late 1980s, such as the sinking of cross-Channel ferry the Herald of Free Enterprise in 1987, the oil platform Piper Alpha disaster in 1988, and the Marchioness Thames river boat collision in 1989. More than 400 people lost their lives in these three disasters, but no one individual or organisation was brought to account. Sentence 2: 100 or more people lost their lives in a ferry sinking.
