The answer given for Question No.56 in the SAT paper by SIERT is wrong. Let us all write a mail to SIERT to force them to recheck the answer of Q. no. 56. Either they must prove us wrong or they should accept our answer/give a bonus mark for this question. I request you all to send a mail to SIERT, their email id. is siert_udr@yahoo.co.in and create a pressure on them to accept the reality. Given below is the format of the mail which you can use -

SIERT has given the answer as option (1), it should be option (2)
The question was -
"Federalism' means more than one level of Govts. in a country; How many levels of Govt. are there in our country -
(1) Two (2) Three (3) Four (4) Five

in Chapter no.1- The Indian Constitution of class VIII, NCERT book, page no.11 discusses about the Key features of the Indian Constitution. The first feature given is Federalism - This refers to the existence of more than one level of government in the country. In India, we have governments at the state level and the centre. Panchayati Raj is the third tier of government and you have read about this in your class VI book.
Chapter no. 2 of class X NCERT book, Federalism, Page no 16 says - The Constitution originally provided for a two-tier system of government, the Union Government or what we call the Central Government, representing the Union of India and the State governments. Later, a third tier of federalism was added in the form of Panchayats and Municipalities.
The above two quotes clearly proves that the answer of Question no.56 should be option (2) rather then option (1) as been claimed by SIERT, Rajasthan.
