Who is one of your state's U.S. senators now? (2025 #23 · 2008 #20)Either of your two senators: Mike Rounds and John Thune.
Name your U.S. representative. (2025 #29 · 2008 #23)South Dakota has one at-large seat, so everyone in South Dakota has the same representative: Dusty Johnson.
Who is the governor of your state now? (2025 #61 · 2008 #43)Larry Rhoden.
What is the capital of your state? (2025 #62 · 2008 #44)Pierre.

The senator and capital questions are also among the 65/20 questions on the 2008 version (and the governor question on the 2025 version), so applicants studying only the 20 starred questions still need these answers.
