Sophie undergoes geography quiz

Big Brother challenged Sophie to a geography quiz last night.

She had to place countries on a map, which each correctly-positioned country winning a song to be played into the house later that evening.

"I'm being sent back to school!" she told the group before explaining the rules of the quiz.

"Oh, another silent evening then," said Marcus, while Siavash tried to show where certain places were on an imaginary map.

"I think I know where the UK is, it's the funny little one, isn't it?" she said.

"Talk about sticking it in and breaking it off," said Marcus. "They just want to make you look bad."

During the task, Sophie correctly located the USA and Brazil, winning songs for Charlie and Rodrigo.

However, she placed Iran where France is, Iceland in China, Japan in Senegal, Germany in the African continent and Sweden where Kazakhstan is located.

"I swear I've never heard of these countries in my life," she admitted. "I didn't know all these countries were joined to each other."
