Example Input: Article: Alice's mother died when she was five. Although her brothers and sisters were loving and caring, their love couldn't take the place of a mother's. In 1925 Alice became my mother and told me that her family couldn't even afford her a doll. One afternoon in December 1982, when I was getting ready for Christmas, I suddenly decided to buy two dolls, one for my five-year-old daughter, Katie, and one for my old mother. Things went smoothly when a friend told me that his dad, who played Santa Claus in my area, would be willing to make a visit on Christmas morning to our home with the gifts! Knowing that my parents would also come to my house, I began to get ready for the most memorable day of my mother's life. Christmas Day arrived and so did Santa Claus at the planned time. Katie was very excited and happy all the time to welcome the Santa. My mother was enjoying watching Katie welcoming this special guest. As Santa turned to leave he looked again into his bag and took out one more gift. As he asked who Alice was, my mother, without thinking of her name being called, said that she in fact was Alice. Santa handed her the gift with a message card that read: For Alice: I was cleaning out my sleigh before my trip this year and came across this package that should be sent on December 25, 1925. The gift inside has aged, but I felt that you might still wish to have it. Many apologies for the lateness of the gift. Love, Santa Claus My mother was very excited and deeply moved to tears. She couldn't speak but only held tightly in her arms the doll she had waited fifty-seven years to receive as tears of joy flew down her face. That doll made my mother the happiest "child".
Question: Why couldn't Alice get a doll as a child?
Options: (A) Because her mother died quite early. (B) Because her family disliked her. (C) Because her family was very poor. (D) Because Alice didn't love dolls.
Example Output: C

Example Input: Article: WASHINGTON-School lunches have been called many things, but a group of retired military officers is giving them a new label: national security threat. That's not a reference to the mystery meat served up in the cafeteria line either. The retired officers are saying that school lunches have helped make the nation's young people so fat that fewer of them can meet the military's physical fitness standards, and recruitment will be difficult. A new report being released Tuesday says more than 9 million young adults, or 27 percent of all Americans ages 17 to 24, are too overweight to join the military. Now, the officers are advocating for passage of a wideranging nutrition bill that aims to make the nation's school lunches healthier. The military group acknowledges that other things keep young adults out of the armed services, such as a criminal record or the lack of a high school diploma. But weight problems that have worsened over the past 15 years are now the leading medical reason that recruits are rejected. Although all branches of the military now meet or exceed recruitment goals, retired Navy Rear Adm. James Barnett Jr., a member of the officers group, says the _ trend could affect that. "When over a quarter of young adults are too fat to fight, we need to take notice," Barnett said. He noted that national security in the year 2030 is "absolutely dependent" on reversing child obesity rates. This isn't the first time the military has gotten involved in the debate over school lunches. During World War II, military leaders had the opposite problem, reporting that many recruits were rejected because of stunted growth and inadequate nutrition. After the war, military leaders pushed Congress to establish the national school lunch program so children would grow up healthier. Today, the group is urging Congress to eliminate junk food and highcalorie beverages from schools, put more money into the school lunch program and develop new strategies that help children develop healthier habits.
Question: What is the main problem of the lunches in schools according to the military officers?
Options: (A) The meat in the lunches is mysterious. (B) The lunches are too expensive. (C) The lunches contain too much fat. (D) There is inadequate nutrition in the lunches.
