Which of the following serves as the exposition of the story (The Witch by Edilberto K. Tiempo)?

When I was twelve years old, I used to go to Libas, about nine kilometers from the town, to visit my favorite uncle, Tio Sabelo, the head teacher of the barrio school there. I like going to Libas because of the many things to eat at my uncle’s house: cane sugar syrup, candied meat of young coconut, corn and rice cakes, ripe jackfruit, guavas from trees growing wild on a hill not far from Tio Sabelo’s house. It was through these visits that I heard many strange stories about Minggay Awok.
