Central Board Of Secondary Education [CBSE] — difficult sst paper

I am anananya mishra studying class 10. I received set 3 in sst exam. Question 24 is really unfair because the data was updated in 2007 and new reg part might have emerged ; then how can this question be asked for no provocation. What is the use of mugging reg parties and sym for all states? Are we all going become future politicians? The same ques in set1 2 isn't worth for 5 marks. We are all students then how can cbse be partial to one?
I request cbse to provide us full 5 mark
