Input: Consider Input: Article: My 11-year-old son and I rides bikes to and from his school every day. I accompany him on the 20-minute ride through Manhattan, drop him off and return at the end of day to pick him up. We always ride together; sometimes he leads; sometimes I do. And as we ride, we communicate the ways to minimize   the dangers: Don't go too fast, and watch out for doors suddenly swinging out from parked cars and jaywalking pedestrians, etc. Some friends worry about the risk of riding in traffic, but is there a better way to let my son know how to deal with traffic dangers? But recently he requested me to start hanging back a half block or so. This way he could enjoy the feeling of riding on his own, with the security of knowing that I was nearby in case he needed me. This is healthy, of course, as my son needs space to develop independence in preparation for his inevitable (,) departure from home. However, that means soon he will want to ride to school on his own, and I will no longer have this wonderful routine. "Let your children go if you want to keep them." I understand this and am trying to let my son go in age-appropriate phases, but I still suffer. It's one of the most troubling experiences of parenthood -- recognizing that your presence is becoming less welcome. My dilemma as a husband mirrors the concern I feel as a parent. My wife has just left on a six-month mission to cover the situation in Libya. In the days leading up to her departure, we spoke openly about the possibility, however unlikely, that she might be killed. But while I influence her decisions, I do not control them. Finally, it was her decision. I know that letting go is the wisest path in this case too. As we travel through life's phases, we must let go of so much. And I don't think it gets easier with practice. But maybe just accepting that eventually we will have to let go is the secret to living a full life. 
 Answer: To teach his son to ride in traffic.

Output: Why does the writer accompany his son on his daily ride to school?

Input: Consider Input: Article: On November 15th, 2014, children aged 8 to 12 got together in five cities around the world to participate in the first Global Children's Designation. The event that was organized by a Dutch company called Unexpect, challenged kids to come up with solutions for some of the world's most pressing problems in a day! The day began with the kids listening to the various challenges that were related to their particular cities and towns. The teams were then asked to brainstorm about which problem they were going to handle and how. There were so many amazing ideas produced on that day. While some of the ideas were far from perfect, there were many that could be practical like the smart cars which can ease traffic pressure by telling traffic lights of its arrival and also guiding the drivers to the best possible route . Emer Beamer, the founder of Unexpect, says the purpose of the project is to introduce children to skills they probably never learn in class. She says that for most part, schools focus on teaching things that they will most likely never need to know again. She believes that for kids to be successful in the world, they should be learning how to be creative, handle new technologies and deal with unexpected situations. Though the first global design challenge was relatively small, involving only a few hundred of the two billion youngsters that are bursting with ideas, the next one will be much bigger. That's because in 2015, Unexpect plans to distribute free tool kits  to any school that is interested in hosting their own Children's Designation Challenge. We can't wait to see what ideas kids will come up with next. 
 Answer: To predict some unexpected situations.


Output: What does the project of Unexpect aim to do?
