Write a multi-choice question for the following article: 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.

Q: Write a multi-choice question for the following article: Article: A blue hole is a flooded sea cave with a hole that opens up at the land's surface. These cave systems form in carbonate rock, often on islands. Some blue holes have very special rock formations and water chemistry. Far below sea level, they contain some of the harshest environments on Earth, with no oxygen and no light. Yet these areas are filled with life forms that have adapted to the extreme conditions. Information gathered from these blue holes is helping scientists to increase their understanding of biology, archaeology and geology. But exploring these blue hole environments brings danger as well as discovery. Blue holes get their name from the color1 some have when seen from the air. The color1 is usually a reflection of the sky on the water. But not all of these cave systems have blue surfaces. Some contain dark or muddy water. Blue holes are the result of erosion in which water breaks down rock. Rain falling thousands of years ago contained chemicals which slowly wore away at the limestone landmass. These holes were later filled with sea water as the sea level changed. The rising and falling of sea levels and the mixture of salt and fresh water further wore away at these cave formations. Blue holes are vertical caves. But they can also have horizontal cave formations that may be hundreds of meters long. These flooded cave systems can be found in the ocean, or they can be found inland. Ocean caves are affected by tides, so they always have water movement. But blue holes on land are very still. They have several layers of water, chemicals, and bacteria. The top layer of fresh water comes from rainfall. This layer acts like a cap on top of the layered mixture, and keeps out oxygen from the atmosphere. The fresh water floats on a denser layer of saltwater. Underneath this is a layer of poisonous hydrogen sulfide, produced by bacteria living in the water. Underneath this layer is anoxic seawater -- water that does not contain any oxygen. Underwater caves are probably one of the least explored ecosystems...

Write a multi-choice question for the following article: Article: The average British 22 year-old has more than 1,000 online friends on sites like Facebook, compared to those in their fifties who have fewer than 20, according to a new study. The "Facebookgeneration gap" has been highlighted in a new piece of research which shows that the average 22 year-old claims to have 1,000 or more friends on sites like Facebook. People in their twenties have more than 50 times as many digital friends as those who are over 50 years old, despite the popularity of sites like Facebook with the older generations, says a study conducted by consumer research group Intersperience. The news comes during the same week Facebook's second-in command, Sheryl Sandberg, is visiting the UK to deliver a speech at the London School of Economics. Facebook's chief operating officer is going to speak about how the social web has transformed people's friendships and relationships. The survey found that there was a clear link between people's age and the number of online friends they have.The researchers found that those aged 13 to 16, have an average of 450 friends on social networks, with girls having slightly more friends that boys.People in their thirties tend to have between 100 and 200 friends, while those in their forties have between 50 and 100. However, those using sites such as Facebook over the age of 50, tended to have 20 or less friends.The oldest person surveyed was 70 years old. Paul Hudson, Intersperience's chief executive, said: "Our research underlines fundamental changes taking place in British society as a result of finally entering the digital age.Half of the UK population are on Facebook now.In a social media context, a 'friend' means something different to a 20 year old than to a 50 year old." He added: "Social networking activity is just one example of how different groups are adapting to the digital age at different paces.In this case, age is the determining factor - however in other instances it is not."
