Explicação:
Nos verbos to be nas frases afirmativas também poderia apenas acrescentar o not ... mas nas minhas respostas acima não botei porque eu queria encurtar mais a frase para não ficar muito comprida.
Mas se achar que é mais difícil dessa maneira que fiz... não tem problema em apenas acrescentar o not.
Se achar a resposta justificável o suficiente... não tem problema em me seguir!
