1.5. Ana, Biljana, Vesna, and Gordana crossed the river in a canoe as follows: There were three trips from the left to the right bank, each time with two girls in the canoe, one of whom was rowing. On both trips from the right bank to the left, there was only one girl in the canoe. It is known that Ana can only row if she is alone in the canoe, and Biljana can row if she is alone or with Vesna. It is also known that each girl rowed at least once. Which of them rowed twice?

1.5. The girl who rowed twice did not row twice from the left to the right bank (because then she would have rowed a third time, from the right to the left bank). Therefore, Ana and the girl who rowed twice rowed from the right to the left bank. Biljana, Vesna, and Gordana rowed from the left to the right bank. Vesna was in the boat when Biljana rowed. This means Vesna crossed to the right bank twice, so she must have also crossed once from the right to the left bank. Answer: Vesna rowed twice.
