Once Misha, Vitya, and Kolya noticed that they had brought the same toy cars to kindergarten. Misha has a car with a trailer, a small car, and a green car without a trailer. Vitya has a car without a trailer and a small green one with a trailer, and Kolya has a large car and a small blue one with a trailer. What type of car (by color, size, and presence of a trailer) did the boys bring to kindergarten? Explain your answer.
If Kolya brought a small blue car with a trailer, then Vitya should have brought a car with a trailer, but Vitya's is green. This means Kolya brought a large car, and Vitya did not bring a small one, that is, a car without a trailer. Then Misha could not have brought a car with a trailer, and he could not have brought a small car. So, Misha had to bring a green car without a trailer. Thus, each of the boys brought a large green car without a trailer.

## Answer

a large green car without a trailer.
