Example Input: What if you could drain all of Earths oceans? What would it look like? You might be really surprised. You see that the surface has two main features. It has continents and ocean basins. Continents are large land areas. These are the areas that are mostly above sea level. Ocean basins extend from the edges of continents. They include the ocean floor and Earths deep ocean trenches. You will also notice the ocean floor is not flat. It too has many Continents are much older than ocean basins. Some rocks on the continents are billions of years old. Ocean basins may only be millions of years old. Because the continents are so old, a lot has happened to them! As we view the land around us, we see landforms. Landforms are physical features on Earths surface. These features change over time, but how? There are actually two types of forces at work. <sep>What are two elements of ocean basins?<sep>Basins and continents
Example Output: No

Example Input: When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison. <sep>In the last 100 years, how much has the agricultural clearing grown and how is it used?<sep>It has tripled, and used for cattle
Example Output: No

Example Input: The letterhead on correspondence still bears the Bexar County Legal Aid name, even though the organization is no longer. Texas Rural Legal Aid - known for its fearless and sometimes controversial advocacy of the poorest of the poor - last week took over four other corporations serving the legal needs of the indigent in Southwest Texas, including the one in Bexar County. The new 68-county legal aid organization has yet to be named and stretches from El Paso to Corpus Christi, Harlingen to Austin. The leader for the super-sized law firm has big plans. "I'm more interested in looking at what we as advocates can do to address the serious problems of poverty than the number of cases we close," said David Hall, the TRLA executive director. In the Rio Grande Valley, Hall's attorneys set up separate groups to assist small-business owners and residents with low-interest loans and legal representation. They also operate a legal arm that assists migrant workers from Texas to Kentucky. Now, Hall said, he wants to make services to the poor more efficient by working with law students who will handle less complicated legal matters, allowing licensed attorneys to take more "high impact" cases to court. "What we need to do is handle cases as efficiently as we can, leveraging the amount of time of the lawyer that goes in there and maximizing the number of people that they can help at one time," Hall said. His plan is to place the 110 attorneys on staff in teams working on specialized legal issues. He wants to expand the law clinic it already has with St. Mary's University Law School to involve students at the University of Texas Law School. The law students at St. Mary's interview potential clients, assist them with filling out legal documents and answer the telephones for the legal hotline, freeing up TRLA lawyers to handle the complicated cases, Hall said. By the end of September, Hall said all the attorneys working with the poor in the 68county area will be placed on the same computer network so they can pass cases to the best available attorneys. Last year, board members on the former Legal Aid of Central Texas and Bexar County Legal Aid resisted the merger, saying that the mergers were done illegally and without the input of board members. They also argued that Hall's litigious style hampered their ability to garner funds from Congress. TRLA generated controversy in 1996, when its attorneys challenged the rights of 800 military personnel to vote in Val Verde County elections by absentee ballot after a former Ku Klux Klan member won a county commissioner post. Brendan Gill, the former executive director of the Bexar County group, said he has since come to see the merger as a positive move for South Texas. "I always knew there were good points to merging, just as I knew that there were bad points," Gill said. <sep>What are the functions of Hall's firms in the Rio Grand Valley?<sep>Assist with low interest loans, legal rep. for poor and operate as a legal arm for Texas and Kentucky migrant workers

Yes
