Hello. You forgot to say that this question is about "Secrets in the Stones." You also forgot to show the answer options, the options are:
It suggests that we can never know the purpose of Stonehenge.
It shows that archaeologists are not able to explain the past.
It explains why people are losing interest in the site.
It begins the discussion of different ideas about Stonehenge.
Answer:
It begins the discussion of different ideas about Stonehenge.
Explanation:
The sentence "even though some questions about the site's purpose have been answered, many remain" gives space for a discussion on theories about Stonehenge to be opened, since it is not possible to determine, in fact, the reason why it was created . Thus, we can understand that the author includes this sentence in the article to serve as a hook for the next section of the article, which talks about possible theories about Stonehenge.
