老师～我想请问d选项的A novelist who turned away from literary realism to write romantic stories about the peasant life and landscape of northern Sweden这个是什么结构呀？是做的Selma Lagerlof 的同位语吗？因为我做题的时候觉得这个句子有点奇怪，把 a novelist 一个没有谓语的一句话错误直接排除了。因为之前在做这个题我也是通过主语重复了来排出选项的：Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year—they are often green and striped, or have plenty of bumps and bruises—heirlooms are more flavorful and thus in increasing demand. 所以想问问应该怎么样区别这两个情况。谢谢~
