How benzene is obtained from benzoic acid ?

Arrange the following compounds in the increasing order of their property as indicated. Benzoic acid, 4-nitrobenzoic acid, 3,4-dinitro benzoic acid, 4-methoxy benzoic acid (acidic strength). Presence of electron withdrawing group (EWG) makes an acid more aidic. As the distane between EWG and -COOH group increases, acidity decreases.
