QUESTION: 8

Sourya committee had proposed the establishment of Sourya Institutes of Technology (SITs) in line with Indian Institutes of Technology (IITs) to cater to the technological and industrial needs of a developing country.
Which of the following can be logically inferred from the above sentence?
Based on the proposal,
(i) In the initial years, SIT students will get degrees from IIT.
(ii) SITs will have a distinct national objective.
(iii) SIT like institutions can only be established in consultation with IIT.
(iv) SITs will serve technological needs of a developing country.

Solution:

Statement (i) - nothing is mentioned in the passage from where SIT students will get degree. So, it is wrong statement.

Statement (ii) - " to cater to the technological and industrial needs of a developing country." this line supports statement (ii). It means Sourya has distinct national objectives.

Statement (iii) - Nothing is mention about consultation with IIT so this makes statement (iii) false.

Statement (iv) - Again this statement "to cater to the technological and industrial needs of a developing country." directly supports statement (iv).

So, only statements (ii) and (iv) are correct. Option C correct .
