Read the following paragraph and determine if the hypothesis is true:

La aventura de un fotógrafo en La Plata is an Argentine novel, written by Adolfo Bioy Casares. It was first published in 1985. In the prologue to the 2005 edition, the author admits that it is possible that the novel alludes, subconsciously, to the desaparecidos, stating, “I do not believe that one can have such a terrible nightmare and refrain from writing about it in the morning.”

Hypothesis: Adolfo first began writing in 1983.
