(CNN) -- A federal court jury in Florida convicted seven people of participating in a global child pornography trafficking enterprise, according to the Department of Justice. Jurors convicted the seven Wednesday of multiple counts of child exploitation, pornography and obstruction of justice. Members of the organization used Internet news groups to swap and share "illegal images and videos depicting prepubescent children, including toddlers, engaged in various sexual and sadistic acts," prosecutors said. An indictment filed in the case detailed interactions between group members as they swapped and commented on images. "My thanks to you and all the others that together make this the greatest group of pedos to ever gather in one place," Freeman wrote in response to one posting, according to the indictment. And a posting from Castleman, cited in the indictment, read, "Thanks to all for the wonderful material that has been posted." An Australian constable who infiltrated the group in August 2006 was among 50 witnesses testifying at trial. He told the jury that the group traded more than 400,000 images and videos of child sexual abuse before being dismantled by law enforcement, according to the Justice Department statement. Each defendant faces a sentence of 20 years to life in prison, fines and the possibility of supervised release for the rest of their lives, authorities said. The seven will be sentenced April 14. During the six-day trial, evidence showed the seven participated in what prosecutors called a "well-organized criminal enterprise whose purpose was to proliferate child sex abuse images to its membership during a two-year period." "This was a wide-scale, high-volume, international trafficking enterprise that used sophisticated computer encryption technology and file-sharing techniques," Matthew Friedrich, acting assistant attorney general, said in the statement. The seven defendants were James Freeman of Santa Rosa Beach, Florida; Gary Lakey of Anderson, Indiana; Marvin Lambert of Indianapolis, Indiana; Neville McGarity of Medina, Texas; Warren Mumpower of Spokane, Washington; Daniel Castleman of Lubbock, Texas; and Ronald White of Burlington, North Carolina, according to the Department of Justice.

Federal health authorities Monday added 58 types of cancer to the list of covered illnesses for people who were exposed to toxins at the site of the World Trade Center in the aftermath of the September 11 attacks. The addition finalizes a recommendation from Dr. John Howard, administrator of the World Trade Center Health Program. Howard proposed in June that the program accept the recommendations of its Science/Technical Advisory Committee and add some cancers to the coverage list -- 14 categories in all. Firefighters responding to 9/11 at increased cancer risk The advisory committee review called for expanded "coverage for certain types of cancer resulting from exposure to toxins released at Ground Zero." "The publication of this final rule marks an important step in the effort to provide needed treatment and care to 9/11 responders and survivors through the WTC Health Program," Howard said in a statement Monday. The rule is expected to be published Wednesday in the Federal Register, and will take effect 30 days after its publication, Howard said. 9/11 detective dies after battle with lung cancer First responders, volunteers, survivors of the attacks and residents near the site who meet specific qualifications will be eligible for coverage, according to the World Trade Center Health Program. According to the proposed rule, an estimated 950 to 2,150 people would take advantage of the additional coverage. The estimated cost for the total cancer treatment ranges between $14.5 million and $33 million, the proposal said.

Problem: A flood occurs when a river overflows its banks. This might happen because of heavy rains. Floodplains In very flat regions, flood water may spread out on the surface of the land. It then slows down and drops its sediment. If a river floods often, a floodplain develops. A floodplain is an area where a thick layer of rich soil is left behind as the floodwater recedes. Thats why floodplains are usually good places for growing plants. They are very flat areas and they have very rich soils. The Nile River valley is a great example of a floodplain. Each year, the Nile River rises over its banks. This floodwater carries a lot of sediment. This sediment has been eroded off areas of land from upstream. This sediment is dropped as the water slows down after spreading across the land. What is left behind is a very rich soil. Thats why crops can be raised in the middle of a sandy desert. Natural Levees A flooding river often forms natural levees along its banks. A levee is a raised strip of sediments deposited close to the waters edge.

Question: "What might cause a river to overflow its banks?"

Answer: "River valley"

Imagine you are standing in a farm field in central Illinois. The land is so flat you can see for miles and miles. On a clear day, you might see a grain silo 20 miles away. You might think to yourself, it sure is flat around here. If you drive one hundred miles to the south, the landscape changes. In southern Illinois, there are rolling hills. Why do you think this is? What could have caused these features? There are no big rivers that may have eroded and deposited this material. The ground is capable of supporting grass and trees, so wind erosion would not explain it. To answer the question, you need to go back 12,000 years. Around 12,000 years ago, a giant ice sheet covered much of the Midwest United States. Springfield, Illinois, was covered by over a mile of ice. Its hard to imagine a mile thick sheet of ice. The massive ice sheet, called a glacier, caused the features on the land you see today. Where did glaciers go? Where can you see them today? Glaciers are masses of flowing ice.

Question: "In what part of Illinois might you be able to see a grain silo that is 20 miles away?"

OPTIONS:
- no
- yes

Answer: "Northern Illinois"

Response:
no
