The archaeologist's museum has some ancient artifacts that other people want back. Even though the museum obtained the artifacts legally, the archaeologist thinks the museum should return them. Why?

The archaeologist's reasoning rests on a principle: any important ancient artifact belongs to the nation where it was found. Because institutions are obligated to honor that principle, the museum should give the artifacts back.

Notice the word "should" in the last sentence. That's a strong signal that the author is expressing a recommendation, which is what conclusions in Main Conclusion questions often look like. The author isn't just describing facts about the situation; he's telling us what ought to happen.

Also notice the words "Given that" in the last sentence. "Given that" typically works the same way as "since" or "because" by introducing a supporting statement. So the claim that institutions are obliged to honor ownership rights is offered as support for the claim that the museum should return the artifacts. This confirms that "our museum should return the artifacts" is the conclusion, because everything else flows toward it.

Here's how the full argument breaks down:

• Context: The museum has ancient artifacts whose ownership is disputed, and the museum obtained them legally.
• Premise 1: Any important ancient artifact belongs by rights to the nation on whose territory it was discovered.
• Premise 2: An institution is obliged to honor those rights.
• Conclusion: The museum should return the artifacts.

The fact that the artifacts were obtained legally is a concession point. The archaeologist acknowledges this but treats it as irrelevant because the overriding principle about national ownership takes priority. The word "although" signals this concession: "Although the museum has documentation showing that the items were obtained legally..." The "although" tells us that this point won't determine the author's conclusion.

The conclusion is the author's recommendation about what should be done: the museum should return the artifacts. Look for an answer that restates this recommendation.
