Please answer the following question: Read the article and select the best answer. Article: On Easter Day, 1722, Dutch explorers landed on Easter Island . It was the first time that Easter Islanders had met people from the outside world. The strangers were about to discover something very strange themselves --that they were on an island with hundreds of huge stone statues . The Dutch explorers wondered where the Islanders had come from and why and how they had built the statues. Now science is putting together the story. The first people to arrive on the island came there around A.D. 700. The society that developed there was based on fishing and farming to feed the population, which grew to 12,000. Its success showed itself in a way that has become the island's trademark : hundreds of huge stone figures --the moai. None of the moai was standing when scientists first arrived. People put them back up later; but how had a Stone Age society ever made, moved and set them up there in the first place? And why? There are nearly 900 moai on Easter Island, and while the questions about them remain unanswered, no one doubts the years of effort that must have gone into making them. The real killer of the Easter Islanders came from across the ocean. After 1722, it became popular for explorers to visit Easter Island, bringing diseases. The final blow came in 1862, when slave traders came from Peru and took away 1,500 people, one-third of the population. Question: When the first explorers arrived on the island, they _ . Options: A: were frightened by the huge stone statues B: were surprised by what they saw C: set many of the moai on the island upright D: fished and farmed
