Sentence Correction (SC) | Literacy opened up entire realms of verifiable knowledge to ordinary

Hello All,

I dint get this question how the sequence is happening and secondly what is the verb for the literacy is it "opened" ?
if it is then how ? because literacy is not doing the action of opening up of entire realms.....

Also why "having been" is incorrect usage since it is correctly modifies men and women

when we have to sure about the usage of relative pronouns ?

Awaiting for your response !
