Context: The museum contained some interesting information about the Viking ages along with some replicas of the Viking ships they have found in the harbour nearby . Overall , however , it was a pretty boring museum that just seemed rather empty . I would not recommend a separate trip to go and see it . After leaving someone disappointed from the museum , we trekked back up the hill ( with a couple of rest / photo stops ) towards town .

Question: why might the viking ships in the museum have been replicas ?
Options:
0. there have not actually been any authentic ones found
1. The authentic ones are too fragile to be put on display
2. None of the above choices .
3. Someone made replicas and was proud of them
Answer: 1
