Article: My wife and I have always been friendly with the clerks at the local convenience store. I don't think many people appreciate what a difficult job these folks have. They work for a little over minimum wage and I often wonder how they make ends meet. One of the clerks, Charlie, was always wearing his glasses but he didn't one day. I asked him about it and he said they'd been out of order and that he couldn't afford a new pair. His family needed money. It was obvious that he was having a difficult time. We wanted to help him, so we turned to our own eye doctor for assistance with a plan. We had his secretary contact him, asking him to come in for an eye exam for free. We told the doctor to let him order whatever glasses he wanted and that we would pay for them. Although Charlie questioned what was going on, the doctor just told him that someone had offered the money for his new glasses. When we went in to pay the bill, the doctor told us he was so touched by our idea that he _ the exam fee and only charged us for half the price of the glasses! It was so wonderful to see Charlie in her new glasses and he enjoyed telling all the regular customers how the gift came about. I'm sure that upon hearing her story, ideas of kindness may have emerged in the minds of many.
Answer: His old glasses were broken.

Ex Output:
Why didn't the clerk Charlie wear glasses one day?

Article: A recent report says we spend an average of two hours and 40 minutes each day looking at a smartphone. That doesn't mean making calls, but using apps and browsing the Web. Spend that amount of time staring at anything. Checked our email in a restaurant, shared a picture of the food when it arrived, or checked a fact during a conversation only to be drawn into reading more instead of contributing verbally. It's no secret our lives are being affected by our obsession with smartphones. However, never before has this phenomenon been displayed so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10. 5 million times. Ironically, YouTube's statistics show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phone. The short film, written by and starring actress Charlene deGuzrnan, shows groups of people in various social situations, the majority of which are completely attracted by their phones instead of the world around them. It's depressing because we' ve all seen it, and sad because to a certain extent, we all do it.
Answer: Concerning.
