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.
Chokwe Selassie got the idea to develop the app from______.
选项 A、his own experience
B、a recent news report
C、his friends
D、his mother
答案A
解析 细节题。根据文章第一段第二、三句可知，乔科伟-塞拉西是在最近的一个早晨他母亲开车送他去上学的时候得到的灵感，他们的车在经过一个坑洞时被损坏了，所以选项A(他自己的经历)正确。
