Yo pienso que es algo justo ya que tiene lógica en que nadie es culpable asta que se demuestre lo contrario ya que tú no puedes culpar a alguien de algo sin pruebas irrefutables.
If you have to complete with a correct verb, this sentence should be complete in the following way;
"el horno ESTÁ en la cocina". This would mean that the oven IS in the kitchen.
the verb "está" derives from "estar." it is use in present tense and simple form because the noun is in singular. In this case, it would make reference to the place in which the oven is, the place in the house.
