参考答案：A

解析： As a super hero in her own right, Xena is a female piglet cloned from fetal-pig skin cells. She may prove to be more than the latest addition to the biotech clone farm. Because of similarities between porcine and human organs, the techniques that made Xena may eventually create a supply of genetically modified pig livers that would be acceptable to the human immune system.语义逻辑推理判断。原文认为“Because of similarities between porcine and human organs，the techniques that made Xena may eventually create a supply of genetically modified pig livers that would be acceptable to the human immune system．”即“鉴于猪和人的器官有相似性，创造了Xena的技术必将创造出可以为人类免疫系统接受的转基因猪肝脏”，由此可推断由于猪和人内脏器官有相似性，未来技术将会使得猪的肝脏移植到人身上。因此，题干的说法是正确的。 注意：同义词替换。本题需掌握porcine与题干中pig同义。
