求助：OG13 SC 132 和 PREP2008 177

1.OG13 SC 132
132.  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.
(A)  Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
(B)  Although heirloom tomatoes, grown from seeds saved during the previous year, appear less appetizing than most of their round and red supermarket cousins
(C)  Although they appear less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year
(D)  Grown from seeds saved during the previous year, heirloom tomatoes appear less appetizing than most of their round and red supermarket cousins
(E)  Heirloom tomatoes, grown from seeds saved during the previous year, although they appear less appetizing than most of their round and red supermarket cousins

OG上对C的解释是代词在先行词的前面。但是，OG上也有很多正确的句子代词在先行词的前面，比如说31题和74题，这一点应该如何解释呢？
31 Even though many of her colleagues were convinced that genes were，relatively simple and static,Barbara McClintock adhered to her own more complicated ideas about how genes might operate。。。。
74 Although it covers the entire planet, Earth’s crust is neither seamless nor stationary, but rather。。。


另外PREP2008 177，正确答案是For the farmer who takes care to keep them cool,  provided with high-energy feed, and milked regularly, Holstein cows will produce an average of 2,275 gallons of milk each per year.

这里两个修饰语在主句前面没有问题吗？
对比OG52 题的B选项，For Josephine Baker, long before it was fashionable to be an expatriate, Paris was her home,and she remained in France during the Second World War as a performer and an intelligence agent for the Resistance.

OG给出的解释是：For Josephine Baker … heris redundant and awkward; putting two introductory elements together before the main clause is awkward

那么PREP 177为什么没有这个问题呢？它也是两个修饰语在主句前面啊，求解释

1.C中的they不能指代cousins吧，因为都是主语，优先指代heirloom tomatoes，指代应该没有问题吧？是不？
2. ...

1. 嗯，指代没有问题，昨天看晕了。C选项语法应该没问题，但在架构问题也蛮大的，两个破折号是解释前面一句话，所以前面一句应当是less appetizing than most of their round and red supermarket cousins，而不是during the previous year。
2. to keep them cool, keep them provided with high-energy food, and keep them milked regularly的平行。

2.177好像不是三个平行的结构，前面一个介词短语，后面两个并列的分词短语，这应该就是两个修饰语吧

同意对OG这一题C选项解释的批判。我觉得C项最大的问题就是两个they指代不一样的，一个是heirloom tomatoes一个是cousins。

prep2008 177 没有两个修饰语在主句前面啊，就是for the farmer who takes care to keep them+三个平行部分，
