Question: Read the following article and select the best answer. Article: While I was on my way to Walmart, I was greeted by an elder woman who was working at the door as a greeter, I had a return to make so she stopped me and asked to tag my bag. Usually I would have gotten annoyed because I know I don't steal, so why does my bag need to be tagged? I'd just witnessed someone ahead of me being not so nice, and treating the lady like she was a nobody. I could see this lady looked to be at retirement age, trying to make ends meet. The look on her face and the energy she gave was that of someone afraid and not knowing where they stood in life. Not to mention the person ahead of me who'd just snatched a bag back from her and stormed off without even saying thank you. I could tell this woman was hurt by that, and no one knows how many people had been treating her that way all day long. What if she was a grandmother who'd recently taken care of her grandchildren for whatever season? What if her husband she had to support recently fell sick and they couldn't afford the medical expenses, so she had to go back to work? What if she just lost everything she had in her retirement and now she had to go back to work? All she wants is to do her job and do it well. All she wants is to serve customers the way she was trained. All she needs is to be appreciated. Can I be that someone she needs, just for the moment? I looked her in her eyes as she scanned my bag, smiled and said, "Your hair is beautiful and fits you well!" Her face lit up and she smiled back and began to tell me how much easier it is to manage. It was salt-and-pepper hair and was cut in the prettiest style. She handed my bag back, smiled and told me the service desk was straight down to my left. I said "Thank you!" Question: By saying "Your hair is beautiful and fits you well." the author wanted to _ . - make the old woman feel appreciated - please her so as not to let her bag tagged - praise her for her hair style and clothes - confirm her hard work and special beauty
Answer: make the old woman feel appreciated

Question: Read the following article and select the best answer. Article: After 21 years of marriage, my wife wanted me to take another woman out to dinner and a movie. The other woman my wife wanted me to visit was my mother, who has been a widow for 19 years, but the demands of my work and my three children had made it impossible to visit her often. That Friday after work, when I arrived at her house, my mother waited in the door with her coat on. She had curled her hair and was wearing the dress that she had worn to celebrate her last wedding anniversary. We went to a restaurant that, although not elegant, was very nice and comfortable. My mother took my arm as if she were the First Lady. During the dinner, we had an agreeable conversation, nothing extraordinary but catching up on recent events of each other's life. We talked so much that we missed the movie. As we arrived at her house later, she said, "I'll go out with you again, but only if you let me invite you." I agreed. A few days later, my mother died of a massive heart attack. It happened so suddenly that I didn't have a chance to do anything for her. Some time later, I received an envelope with a copy of a restaurant receipt from the same place Mother and I had dined. An attached note said "I paid this bill in advance. I wasn't sure that I could be there; but, nevertheless, I paid for two plates--one for you and the other for your wife. You w ill never know what that night meant for me. I love you, son." At that moment, I understood the importance of saying in time 'I love YOU' and to give our loved ones the time that they deserve. Nothing in life is more important than your family. Give them the time they deserve because these things cannot be put off till some "other" time. Question: During the dinner, what did they talk about? - Special things. - Some national events. - Each other's daily life. - Movies and dishes.
Answer:
Each other's daily life.
