2 根据下列内容，回答题。
Since the l970s，scientists have been searching for ways to link the brain with computers．
Brain-computer interface(BCI)technology could help people with disabilities send commands to machines．
Recentlv。two researchers，Jose Millan and Michele Tavella from the Federal Polytechnicschool in Lausanne，Switzerland，demonstrated(展示)a small robotic wheelchair directed by aperson’s thoughts．
In the laboratory，Tavella operated the wheelchair just by thinking about moving his left or right hand．He could even talk as he watched the vehicle and guided it with his thoughts ．
"Our brain has billions of nerve ceils. These send signals through the spinal cord (脊髓) tothe muscles to give us the ability to move. But spinal cord injuries or other conditions can preventthese weak electrical signals from reaching the muscles," Tavella says."Our system allowsdisabled people to communicate with external world and also to control devices."
The researchers designed a special cap for the user. This head cover picks up the signals fromthe scalp(头皮) and sends them to a computer. The computer interprets the signals and commandsthe motor/zeal wheelchair. The wheelchair also has two cameras that identify objects in its path.
They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software thatinterprets brain signals and turns them into simple commands. "The practical possibilities that BCItechnology offers to disabled people can be grouped in two categories: communication andcontrolling devices. One example is this wheelchair."
He says his team has set two goals. One is testing with real patients, so as to prove that this isa technology they can benefit from. And the other is to guarantee that they can use the technologyover long periods of time.
BCI is a technology that can__________.

A．help to update computer systems

B．link the human brain with computers

C．help the disabled to recover
