问题    Chokwe Selassie is on a mission to help drivers avoid potholes (路面坑洞). The eighth-grader got his inspiration on a recent morning, when his mother was driving him to school. Their car was damaged as it went over a huge pothole in the middle of the street in their hometown of Jackson, Mississippi. "I decided I was going to do something about the pothole problem in my city, " said Chokwe. His solution: an app that warns drivers when there is a pothole ahead.
   Chokwe developed the app with his friends. " When the app detects a pothole, it is highlighted in red, " Chokwe says. " And if you get close to the pothole, your phone will warn you with a beep. " Drivers can also use the app to report any potholes they encounter, and to look for other routes they can take to avoid roads that have them.
   The app relies on current available information about the streets of Jackson. " It works by using the city’s 311 call system, so it uses information already stored in a database, " Chokwe says. Through the call system, citizens dial 311 to report non-emergency problems—which include potholes. As Chokwe and his friends worked on the app, they also went street by street throughout the city. They determined that focusing on the 10 busiest streets in Jackson would give them a large enough sample size to test it.
   Although the app isn’ t yet available for sale, Chokwe is already looking for ways to improve it. The app remains limited to 10 streets in Jackson, but he hopes to add more, so that it includes every street in the city. And then he wants to go even farther. " I want to keep working on the app until it’s nationwide, " Chokwe says.
Drivers can also use Chokwe’ s app to______.

选项 A、report emergency traffic problems
B、look for information other than potholes
C、choose safer routes without potholes
D、avoid traffic jam caused by potholes

答案C

解析 细节题。根据文章第二段最后一句可知,司机也可以使用该应用程序上报他们遇到的任何坑洞,并寻找其他路线,从而避开有坑洞的路线,所以选项C(选择没有坑洞的更安全的路线)正确。选项A(上报紧急交通事故)、选项B(寻找除了坑洞外的其他信息)和选项D(避免坑洞引起的交通堵塞)文中均未提及。
