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

Ex Input:
 Bin Laden reportedly discussed the planes operation with KSM and Atef in a series of meetings in the spring of 1999 at the al Matar complex near Kandahar. KSM's original concept of using one of the hijacked planes to make a media statement was scrapped, but  Bin Laden considered the basic idea feasible.  Bin Laden, Atef, and KSM developed an initial list of targets. These included the White House, the U.S. Capitol, the Pentagon, and the World Trade Center. According to KSM,  Bin Laden wanted to destroy the White House and the Pentagon, KSM wanted to strike the World Trade Center, and all of them wanted to hit the Capitol. No one else was involved in the initial selection of targets.  Bin Laden also soon selected four individuals to serve as suicide operatives: Khalid al Mihdhar, Nawaf al Hazmi, Khallad, and Abu Bara al Yemeni. During the al Matar meetings,  Bin Laden told KSM that Mihdhar and Hazmi were so eager to participate in an operation against the United States that they had already obtained U.S. visas. KSM states that they had done so on their own after the suicide of their friend Azzam (Nashiri's cousin) in carrying out the Nairobi bombing. KSM had not met them. His only guidance from  Bin Laden was that the two should eventually go to the United States for pilot training. Hazmi and Mihdhar were Saudi nationals, born in Mecca. Like the others in this initial group of selectees, they were already experienced mujahideen. They had traveled together to fight in Bosnia in a group that journeyed to the Balkans in 1995. By the time Hazmi and Mihdhar were assigned to the planes operation in early 1999, they had visited Afghanistan on several occasions. Khallad was another veteran mujahid, like much of his family. His father had been expelled from Yemen because of his extremist views. Khallad had grown up in Saudi Arabia, where his father knew  Bin Laden, Abdullah Azzam, and Omar Abdel Rahman (the "Blind Sheikh"). <sep>How many people were involved in selecting targets to destroy by plane?<sep>2

Ex Output:
Yes

I had drunk too much, I confess, though we all had. Somehow, Tasha and I began to argue the worth of Solevgrad jazz, as inconsequential a topic as I can imagine. She had studied it in school, so she thought herself as an expert. I once had a neighbor who played it constantly, loudly, and badly, so I thought I knew it better. Malaquez tried to mediate, but I saw him as siding with Tasha. So, I think, did she. The subject shifted from music to Tasha's obsession with fame, undoubtedly by a leap that I made. She had no choice but to follow. (I do not remember any of this well, just now, nor do I care to. Those who are truly curious may look at the last act of "Captured Moments.") I remember suggesting, with characteristic tact, that she add Emil to her small list of major accomplishments. Malaquez glanced away, embarrassed. Tasha looked at me as if to say, "I will." She said, "I feel sorry for you, Nardo. I'll see Emil home." "Yes," I said, "Do that," and did not care what she did, or why. Emil asked, "You're all right?" I muttered something he must have interpreted as assent. They both walked up to Emil's home while I watched the scarlet moonlight ripple on distant waves. Disgusted with Tasha but more disgusted with myself, I finally realized she would not return that night and went into The Sleeping Flamingo to drink myself to sleep. She had not come home when I woke in mid-morning. <sep>What discussion topic does Nardo feel that Tasha was obligated to follow along with?<sep>Her idea that she was an expert in Solegrad jazz

No
