Data Science Learning Path Quiz questions

[Gualigee]

I have completed the interactive lessons for Data Science Learning Path.

https://community.alteryx.com/t5/Interactive-Lessons/tkb-p/interactive-lessons

I have two questions:

I only know the last one should be selected. 

I think only the penultimate one should be selected, but at least two should be selected.

Can you please help with these two question?

I also attached the quiz compilations for your reference. 

Thanks
