Questão 5 ENEM 2018: Interpretação de texto

‘Is it your opinion, Winston, that the past has real
existence?’ \[…\] O’Brien smiled faintly. ‘I will put it more
precisely. Does the past exist concretely, in space? Is
there somewhere or other a place, a world of solid objects,
where the past is still happening?’
‘No.’
‘Then where does the past exist, if at all?’
‘In records. It is written down.’
‘In records. And — —?’
‘In the mind. In human memories.’
‘In memory. Very well, then. We, the Party, control all
records, and we control all memories. Then we control the
past, do we not?’
