Input: Sahara
By 6000 BCE predynastic Egyptians in the southwestern corner of Egypt were herding cattle and constructing large buildings. Subsistence in organized and permanent settlements in predynastic Egypt by the middle of the 6th millennium BCE centered predominantly on cereal and animal agriculture: cattle, goats, pigs and sheep. Metal objects replaced prior ones of stone. Tanning of animal skins, pottery and weaving were commonplace in this era also. There are indications of seasonal or only temporary occupation of the Al Fayyum in the 6th millennium BCE, with food activities centering on fishing, hunting and food-gathering. Stone arrowheads, knives and scrapers from the era are commonly found. Burial items included pottery, jewelry, farming and hunting equipment, and assorted foods including dried meat and fruit. Burial in desert environments appears to enhance Egyptian preservation rites, and dead were buried facing due west.

What items replaced previously items made of stone?
Output: Metal objects

Input: Capital punishment in the United States
Present-day statutes from across the nation use the same words and phrases, requiring modern executions to take place within a wall or enclosure to exclude public view. Connecticut General Statute 54100 requires death sentences to be conducted in an "enclosure" which "shall be so constructed as to exclude public view." Kentucky Revised Statute 431.220 and Missouri Revised Statute 546.730 contain substantially identical language. New Mexico's former death penalty, since repealed, see N.M. Stat. 31-14-12, required executions be conducted in a "room or place enclosed from public view." Similarly, a dormant Massachusetts law, see Mass. Gen. Law ch. 279 60, required executions to take place "within an enclosure or building." North Carolina General Statute 15-188 requires death sentences to be executed "within the walls" of the penitentiary, as do Oklahoma Statute Title 22 1015 and Montana Code 46-19-103. Ohio Revised Code 2949.22 requires that "[t]he enclosure shall exclude public view." Similarly, Tennessee Code 40-23-116 requires "an enclosure" for "strict seclusion and privacy." United States Code Title 18 3596 and the Code of Federal Regulations 28 CFR 26.4 limit the witnesses permitted at federal executions.

What state's law requires that capital punishment occur "within the walls" of a penitentiary?
Output: North Carolina

Input: Washington University in St. Louis
The Washington University School of Medicine, founded in 1891, is highly regarded as one of the world's leading centers for medical research and training. The School ranks first in the nation in student selectivity. Among its many recent initiatives, The Genome Center at Washington University (directed by Richard K. Wilson) played a leading role in the Human Genome Project, having contributed 25% of the finished sequence. The School pioneered bedside teaching and led in the transformation of empirical knowledge into scientific medicine. The medical school partners with St. Louis Children's Hospital and Barnes-Jewish Hospital (part of BJC HealthCare), where all physicians are members of the school's faculty.
