Ex Input:
Johnnie had a set of small volumes of English verse, extensively annotated by his own hand, which Stoddard had brought to her early in their acquaintance, leaving it with her more as a gift than as a loan.  She kept these little books after all the others had gone back.  She had read and reread them--cullings from Chaucer, from Spenser, from the Elizabethan lyrists, the border balladry, fierce, tender, oh, so human--till she knew pages of them by heart, and their vocabulary influenced her own, their imagery tinged all her leisure thoughts.  It seemed to her, whenever she debated returning them, that she could not bear it.  She would get them out and sit with one of them open in her hands, not reading, but staring at the pages with unseeing eyes, passing her fingers over it, as one strokes a beloved hand, or turning through each book only to find the pencilled words in the margins.  She would be giving up part of herself when she took these back.  Yet it had to be done, and one miserable morning she made them all into a neat package, intending to carry them to the mill and place them on Stoddard's desk thus early, when nobody would be in the office.  Then the children came in; Deanie was half sick; and in the distress of getting the ailing child comfortably into her own bed, Johnnie forgot the books.  Taking them in at noon, she met Stoddard himself. <sep>In what books were the words from Chaucer and Spenser?<sep>Small volumes of English verse

Ex Output:
Yes

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>How can habitats be lost?<sep>killed by invasive tall grass

(CNN) -- Declaring 2010 "The best year in safety performance in our company's history," Transocean Ltd., owner of the Gulf of Mexico oil rig that exploded, killing 11 workers, has awarded its top executives hefty bonuses and raises, according to a recent filing with the U.S. Securities and Exchange Commission. That includes a $200,000 salary increase for Transocean president and chief executive officer Steven L. Newman, whose base salary will increase from $900,000 to $1.1 million, according to the SEC report. Newman's bonus was $374,062, the report states. Newman also has a $5.4 million long-term compensation package the company awarded him upon his appointment as CEO in March 2010, according to the SEC filing. The latest cash awards are based in part on the company's "performance under safety," the Transocean filing states. "Notwithstanding the tragic loss of life in the Gulf of Mexico, we achieved an exemplary statistical safety record as measured by our total recordable incident rate and total potential severity rate," the SEC statement reads. "As measured by these standards, we recorded the best year in safety performance in our Company's history." The company called that record "a reflection on our commitment to achieving an incident-free environment, all the time, everywhere," the SEC filing states. The company did not respond to an e-mail from CNN seeking comment. The April 20, 2010, explosion on the Deepwater Horizon rig injured 17 workers and killed 11 others, including nine Transocean employees, according to the SEC filing. It has been called the worst spill in U.S. history. The well was capped three months later, but not before millions of barrels of oil spilled into the Gulf. In January, President Barack Obama's National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling released a report that spread blame for the accident among Transocean, BP -- which leased the rig -- and Halliburton, which installed the rig's cement casing. <sep>On what date did the worst oil spill in US history occur?<sep>March, 2010
