Last Saturday our town held a small science fair in the school hall. Dana, who is my cousin, built a model of a wind turbine, and Ruslan showed a simple water filter. The judges walked slowly between the tables, and they asked every pupil a question. One judge asked Dana, "How does your turbine produce electricity?" Dana explained that the moving blades turn a small motor. Because the model worked well, the judges gave her a prize. What a clever idea it was! Ruslan was disappointed, but he decided to improve his filter. "Come and see our project next year," he told the visitors. Nobody left the hall until the fair was over.
Which sentence has the same meaning as "Because the model worked well, the judges gave her a prize" but is a compound sentence?

The original sentence shows a cause (the model worked well) and a result (the prize). A compound sentence with "so" keeps the same order of cause and result: "The model worked well, so the judges gave her a prize". The variant with "so" placed after the prize reverses cause and result. The variant with "but" expresses contrast. The variant with "because" is complex, not compound, and also changes the tense meaning.
