Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: 1986 — Thomás is born with his eyes closed, and he does not open them for several weeks following the birth. Julieta, his mother, is unconcerned, believing that when Thomás is ready and wants to open his eyes, he will. These events instill a strong belief in free will in young Thomás. Two weeks after his birth, Thomás opens his eyes, apparently to look directly at his five-year-old half-brother Francisco.
1992 — Julieta is a wife and a loving mother, working in a hospital emergency department. Her free-spirited youngest son, Thomás, is the product of her marriage to her second husband Alexandre. Pedro, her first husband and father of her eldest son Francisco, lives in Argentina. Pedro and Julieta remain good friends. During childhood, Francisco and Thomás are very close, perhaps too close according to Pedro, with whom they spend a Christmas holiday in Buenos Aires. Julieta is aware of their close relationship and tries to remain understanding. Not long later, Pedro dies.
2008 — Years later, when Francisco is 27 and Thomás 22, Julieta dies. The brothers become lovers and an unusual love story ensues. Thomás is invited to live and train in Russia for a few years in preparation for the Olympics. Though it is the first time they will be apart, Thomás leaves. Francisco struggles without Thomás. He meets a woman in a club and though he tries to pursue a relationship with her, they both realize he is dedicated to someone else. Unable to be apart any longer, Francisco travels to Russia and the brothers reunite.
Who is the father of the boy born with his eyes closed?
