Answer 2

⚫ The Constitution makers were concerned that in an open electoral competition, certain weaker sections may not get elected to the Lok Sabha and the state Legislative Assemblies. 

⚫ They may not have the required resources, education and contacts to contest and win elections against others.

⚫ If that happens, our Parliament and Assemblies would be denied of the voice of an important section of our population making our democracy less representative and less democratic. 

⚫ Those who are powerful and capable may stop them from winning elections. 

⚫Hence the makers of our Constitution thought of a special system of reserved constituencies for the weaker sections.
