2. Vera, Nadya, and Lyuba have dresses of three different colors - pink, purple, and turquoise, and their hats are also of these three colors. Only Vera has the same color for her dress and hat, Nadya's are not pink, and Lyuba has a purple hat. Indicate the colors of the dress and hat for each girl.
Solution. Since Luba's hat is purple, and Nadya's is not pink, Nadya's must be turquoise, which means Vera's is pink. Then Vera's dress is also pink. Nadya's dress and hat are of different colors, so her dress is purple, and Luba's is turquoise.

Answer: Vera has a pink dress and a pink hat, Nadya has a purple dress and a turquoise hat, and Luba has a turquoise dress and a purple hat.

Comment. A correctly justified answer is given - 7 points. The colors of the dress and hat are correctly determined for only one of the girls - 3 points.
