本题考查什么
For the question "Which of the following is correct?", the correct answer is "Provisional Driving Licence (PDL) is valid for 6 months" because the question is testing a specific fact or rule, so the correct option is the one that matches the required value, timing, or legal requirement; the other choices such as "Provisional Driving Licence (PDL) is valid for 12 months" and "Provisional Driving Licence (PDL) is valid for 24 months" do not fit the rule as well.
