阅读下列材料，从下面每题的A、B、C、D四个选项中选出最佳答案。
Are you able to hang (悬挂) clothes? Are you able to put a nail (钉子) into the wall? For many people, doing these things is quite easy. But how do people who have trouble using their hands do these things? Well, they can use artificial (人造的) hands to help them out.
In Suzhou, some engineers are busy making a special hand better. The special hand is helpful and people can control it with the electrical signals (电信号) which come from their bodies.
These engineers hope to make it much better for Xu Min, who lost her right forearm in an accident in 1992. The woman wore the hand to take part in the Cybathlon Challenges in February. She finished tasks like hanging clothes, putting a nail into the wall and taking a nail out of the wall.
"These things are common in our daily lives and people want to test if the special hand, which was created by humans, can work just like a real hand," Xu said. Because she won the competition (比赛) in February, she was more confident about entering the October global finals — Cybathlon2024 in Zurich, Switzerland.
Cybathlon is the top event in the area. The event was first held in 2016. It takes place every four years. The competition tries to create a world without difficulty for people like Xu. In October, the competition will draw many teams from across the world.
Xu was a little nervous about competing with other people and companies from her country and other places. However, she and her team wanted to show their new product and how humans and machines could work together. Xu said she couldn't wait to get the hand ready and start the training.
