swi-prolog function check for list and logical operation

[swipro-learner]

I want to check multiple condition like these into swi-prolog

            if sub_link in links_list1:        
                if ('Who').lower() in sent_split or 'Who' in sent_split:
                    result = 'person'
                    break
                elif (('Where').lower() in sent_split or 'Where' in sent_split) and 'What' not in read_str and 'what' not in read_str:
                    result = 'location'
                    break
                elif ('Why').lower() in sent_split or 'Why' in sent_split:
                    result = 'reason'
                    break

prolog code:

    member(SUBLINK, LINKSLIST),
    (
        member('Who', SENTSPLIT), member('who', SENTSPLIT),
        (
            nb_linkval(result , 'Person')
        ); # I guess if above condition satisfies then it automatically returns without checking further code
        member('What', SENTSPLIT), notmember('what', SENTSPLIT), #notmember, is there cluase like notmember to check `not in list` then correct
        (
            nb_linkval(result , 'Thing')
        );
        member('Where', SENTSPLIT), notmember('where', SENTSPLIT),
        (
            nb_linkval(result , 'where')
        )
    ).

I guess all above iteration behaves like `and` operation, how can I check `or` operation?
