Questions 22-25 refer to the following online chat discussion. 9 ERIC DAVIS [11:01 A.M.] Hi all. I'd like to know how preparations for next month's trade show are going. Are we still on schedule? JIM COCHRANE [11:02 A.M.] We planned out the booth, and it's going to look awesome. All our new exercise machines will be on display. DONNA WRIGHT [11:03 A.M.] We haven't decided on a game yet, though. I want something big and colorful so that it catches everyone's attention. But some people on the marketing team don't see the point of having one. ANNETT LEWIS [11:04 A.M.] Well, I get it. But we'll be letting visitors try out the bikes and other machines. That alone will draw plenty of interest to the booth. DONNA WRIGHT [11:05 A.M.] But we should use a game to give out coupons for our products. Plus, games make it easier to start up conversations with potential customers. JIM COCHRANE [11:06 A.M.] And we want people to submit their business cards for a chance to win a big gift at the end of the show. How about a prize wheel? They're eye-catching and amusing. 30

In particular, the introduction of AI systems into cars is attracting a lot of attention. Car manufacturers in Japan and other countries have been focusing their time and efforts on developing self-driving cars. Within the next few decades, they may become commonplace. What are the benefits of self-driving cars? First, by having an automated driving system control driving, the physical and mental burden on the driver will be significantly reduced. Also, there may be fewer traffic accidents because driving errors by drivers will be reduced. On the other hand, there are some concerns about self-driving cars. First, until self-driving cars are mass-produced, manufacturing costs are expected to be very high. Additionally, if the programs controlling self-driving cars are rewritten through hacking or other means, it may lead to accidents or crimes. Therefore, it is essential to ensure the security of the systems. 解答欄 Self-driving cars may become commonplace.
