Q6:

Heirloom tomatoes, grown from seeds saved from the previous year, only look less appetizing than their round and red supermarket cousins, often green and striped, or have plenty of bumps and bruises, but are more flavorful.

1. cousins, often green and striped, or have plenty of bumps and bruises, but are
2. cousins, often green and striped, or with plenty of bumps and bruises, although
3. cousins, often green and striped, or they have plenty of bumps and bruises, although they are
4. cousins; they are often green and striped, or with plenty of bumps and bruises, although
5. cousins; they are often green and striped, or have plenty of bumps and bruises, but they are

答案E 但A错在什么地方了呢？

I agree with A too. 

Heirloom tomatoes, grown from seeds saved from the previous
year, only look less appetizing than their round and red supermarket cousins,
often green and striped, or have plenty of bumps and bruises, but are more
flavorful.

对 A 最大的争议是 "often green and striped" 有可能修饰 "cousins".  但是原句中 "round and red supermarket cousins"
已经明确表明 "round and red" 修饰 cousins,  不可能 cousins 同时被两个完全相反的状态修饰吧?

将 A简化：

Heirloom tomatoes (, grown from seeds saved from the previous
year,)
        only look less appetizing than their round and red
        supermarket cousins,
(often green and striped, or have plenty of bumps and bruises,) but are more
flavorful.　

看上去句式简单明了．

这解释不对!

还是E对,

既然明白A 最大的争议是 "often green and striped" 有可能修饰 "cousins".那你还选?!

同意A，E中的第二个They中间隔了bumps and bruises，不能清楚指代Heirloom tomatoes。
