Question 1
Boats numbered 1, 2 and 3 are enjoying a voyage on the ocean. Suddenly a storm appears. Heavy raindrops begin to fall, and the wind blows strongly. Huge waves threaten to pull the boats into the storm. The boats must reach the harbour as quickly as possible. Luckily, a distant lighthouse guides them. Which boat can enter the harbour? (The arrow shows the direction into the harbour.)
