T-4-Q12

For the farmer who takes care to keep them cool, providing them with high-energy feed, and milking them regularly, Holstein cows are producing an average of 2,275 gallons of mild each per year.

1. providing them with high-energy feed, and milking them regularly, Holstein cows are producing

2. providing them with high-energy feed, and milked regularly, the Holstein cow produces

3. provided with high-energy feed, and milking them regularly, Holstein cows are producing

4. provided with high-energy feed, and milked regularly, the Holstein cow produces

5. provided with high-energy feed, and milked regularly, Holstein cows will produce

Why choose E? 和"For the farmer who takes care to keep them cool"的逻辑关系？

What's the logic behind it?

provided with high-energy feed, and milked regularly的逻辑主语是cows，

不能选a或b，providing 修饰的主体有歧义，也讲不通；

For the farmaer 。。。是目的状语，修饰奶牛产奶。
