Depends on what the excerpts are
The Alchemist concludes with Santiago at the end of his journey across the sea and sands, back to where he started, dreaming under a sycamore tree. That is until the last line of the novel, "I'm coming, Fatima..." (Epilogue.13); This line shows that Santiago's journey is not yet done and that he will continue to travel even after the end of the novel.
A key detail is something that is important.
A minor detail is something that little and is not that important.
"The Feather Pillow" begins with a blond, young girl named Alicia, who had just recently been newly wed three months prior, in April, to an impassive man named Jordan. The young couple had moved into an almost empty house, which had little services to offer his housebound wife. Day by day, with little to do at home to keep her occupied, Alicia would occupy her time by waiting for her husband's arrival every evening. Soon, however, as seasons changed to autumn, the young girl contracted a mild case of influenza and began to feel languid. As the days followed, her symptoms did not subside, but became even worse. One day with the aid of her husband at her side, Alicia was able to walk around her garden, but unfortunately that was the last day. The following day she was too weak to even get out of bed. The doctors were summoned; unsure of the cause of her deteriorating condition they prescribed rest. The next day arrived, and Alicia's efforts to get out of bed were apparently becoming fruitless. Hallucinations began to plague her thoughts, which made the complications even worse. All that her worried Jordan could do was pace the floor frantically up and down by her bedside begging the doctors to save his wife's life. But with no prevail, the enigmatic doctors could not figure out what was wrong with poor Alicia. With no cure for Alicia's illness, the young wife died two days later. Preparing to wash Alicia's bed-sheets, the servant noticed two small, dark bloodstains. Trying to raise the pillow to the light to further investigate her findings, the heavy weight of the pillow caused it to crash on to the floor. Jordan picked up the pillow and placed it on the dining room table, where he sliced it in half. Beneath the feathers, there was a large parasite with a large proboscis. Within a period of only five days and five nights, this normally small parasite had made a feast of Alicia's blood, and had caused the newly wedded wife to die abruptly.
