本题考查什么

For the question "You have fastened the seat belt and adjusted the rear view and wing (side) mirrors, what are the next steps you should take before moving off?", the correct answer is "Do both of the above (A and B)" because this combined option is correct only because the separate statements it refers to are both valid in this situation; the other choices such as "Check around for pedestrians or other traffic" and "Signal the intention" do not fit the rule as well.
