Question 2 gets an unexpected grading error and I am referred to this forum. All test passed and with the other questions I have 10 / 10. I have allready retried the test, refreshing the notebook first, but it hasnt worked.
I do see that the expected results are different from my actual results. do you know what is wrong?

"Pluto's geological activity and features",
"Insights from New Horizons data",
"Future exploration of Kuiper Belt Objects"

Expected Output:
[
"Unique Topic 1 as a string",
"Unique Topic 2 as a string",
"Unique Topic 3 as a string"
