Simplify the following text for a Grade 7 native English-speaking person.
Original: However at this tribal council , Neleh and Kathy were also forced to choose rocks , when according to the rules they should have been immune , which would in theory automatically eliminate Paschal . Though Paschal chose the purple rock and was eliminated anyway , it is speculated that the fire-making challenge ( which would involve only Neleh and Kathy ) was meant to be used in this case and that production was in error by using the rock tiebreaker .
Simplified: In this situation , Kathy and Neleh drew yellow rocks , and Paschal pulled the purple rock .
