RC Practice - Free Resources for everyday read outside GMAT

Dear All,

I have been looking for some free resources outside GMAT but similar to the GMAT structure for the below mentioned topics:

Abstract Sciences - Logic, Philosophy, Psychology, Intelligence Levels, Aptitudes, Child Bearing and Rearing, etc.
Social Sciences - History, Politics, Economics, Sociology, etc.
Law - Legal History, International Law, Human rights, Legal Theory, Famous legal cases, etc.
Humanities - Classic and Contemporary Art, Literature, Films, Music, etc.

I have liked the History Today's challenging content but it is a paid source.
My expectation is to be more and more familiar with the tough words and structure of the content.
Can someone please help me find some free resources for the same?

TIA
