正确选项是laid up，"was laid up"应该是被动语态，不知道怎么理解，其他几个选项也是，MJJ指点一下
问了gpt，回答的感觉不准确，一会说谓语动词，一会说是表语，我都蒙圈了

Let's think about this step by step:
1) First, let's understand the context:
- Powell got injured (hurt his back)
- The injury was from falling off a horse
- He was in some state for a year due to this injury
2) Let's look at what the different "laid" phrases mean:
- "laid up" = confined to bed/home due to illness or injury
- "laid out" = arranged for display; or dead/prepared for burial
- "laid on" = provided or arranged (like food or entertainment)
- "laid down" = put something down; or established rules
3) Given that Powell was injured and presumably needed time to recover:
- "laid up" makes the most sense as it specifically refers to being confined due to injury or illness
- The other options don't fit the context of injury recovery
Therefore, the correct answer is "laid up."
The sentence should read: "Powell hurt his back when he fell off the horse and was laid up for a year."
This means Powell was confined to bed or home for a year while recovering from his back injury.
