The answer to the question: What is the first name of the person who realized that the boy's skill was in portraiture? is inside the article: James Barton Longacre was born on a farm in Delaware County, Pennsylvania, on August 11, 1794. His mother Sarah (Barton) Longacre died early in his life; his father, Peter Longacre, was the descendant of early Swedish settlers of North America. When Peter Longacre remarried, his son found the home life intolerable, and James Longacre left home at the age of 12, seeking work in the nearby city of Philadelphia. He apprenticed himself at a bookstore; the owner, John E. Watson, took the boy into his family. Over the following years, Longacre worked in the bookstore, but Watson realized that the boy's skill was in portraiture. Watson granted Longacre a release from his apprenticeship in 1813 so that he could follow an artistic muse, but the two remained close, and Watson would often sell Longacre's works.Longacre became apprenticed to George Murray, principal in the engraving firm Murray, Draper, Fairman & Co. at 47 Sansom Street in Philadelphia. This business derived from the firm established by the Philadelphia Mint's first chief engraver, Robert Scot. Longacre remained at the Murray firm until 1819; his major work there was portraits of George Washington, Thomas Jefferson, and John Hancock which were placed on a facsimile of the Declaration of Independence by publisher John Binns; the work cost Binns a total of $9,000 (equal to $147,307 today). Also employed at the Murray firm from 1816 was the man who would be Longacre's predecessor as chief engraver, Christian Gobrecht. Longacre's work at the company gave him a good reputation as an engraver skilled in rendering other artists' paintings as a printed engraving, and in 1819, he set up his own business at 230 Pine Street in Philadelphia.Longacre's first important commission were plates for S.F. Bradford's Encyclopedia in 1820; an engraving of General Andrew Jackson by Longacre based on a portrait by Thomas Sully achieved wide sales. Longacre then agreed to engrave illustrations for Joseph and John Sanderson's Biographies of the Signers of the Declaration..., can you guess it ?
Ans: John

The answer to the question: What rodents are raised communally but kept from nursing from anyone other than their own moms? is inside the article: Mother rodents provide both direct parental care, such as nursing, grooming, retrieving and huddling, and indirect parenting, such as food caching, nest building and protection to their offspring. In many social species, young may be cared for by individuals other than their parents, a practice known as alloparenting or cooperative breeding. This is known to occur in black-tailed prairie dogs and Belding's ground squirrels, where mothers have communal nests and nurse unrelated young along with their own. There is some question as to whether these mothers can distinguish which young are theirs. In the Patagonian mara, young are also placed in communal warrens, but mothers do not permit youngsters other than their own to nurse.Infanticide exists in numerous rodent species and may be practiced by adult conspecifics of either sex. Several reasons have been proposed for this behavior, including nutritional stress, resource competition, avoiding misdirecting parental care and, in the case of males, attempting to make the mother sexually receptive. The latter reason is well supported in primates and lions but less so in rodents. Infanticide appears to be widespread in black-tailed prairie dogs, including infanticide from invading males and immigrant females, as well as occasional cannibalism of an individual's own offspring. To protect against infanticide from other adults, female rodents may employ avoidance or direct aggression against potential perpetrators, multiple mating, territoriality or early termination of pregnancy. Feticide can also occur among rodents; in Alpine marmots, dominant females tend to suppress the reproduction of subordinates by being antagonistic towards them while they are pregnant. The resulting stress causes the fetuses to abort., can you guess it ?
Ans: Patagonian mara

The answer to the question: Whose the nemesis of the only student that knows about Crossbow? is inside the article: The CIA is secretly developing "Crossbow", a space shuttle-mounted laser weapon precise enough to incinerate a single target from outer space, planning to use it for illegal political assassinations. However, they struggle with its power source, and have covertly hired Professor Jerry Hathaway at Pacific Technical University to develop this. Hathaway has assembled a group of genius students in physics to do the work for him, though outside of his graduate student Kent, purposely does not tell them the reason for their research. Hathaway is also embezzling the CIA provided funds intended for research so that he can upgrade his house. Hathaway recruits high-school student Mitch Taylor to join the team. Mitch is roomed with Chris Knight, a "legend" in the physics area. Mitch becomes dismayed that Chris is more of a goof-off than a hard-working student. Chris introduces Mitch to some of the other genius students, including Jordan, "Ick" Ikagami, and his nemesis, the less intelligent Kent. Despite his age and inexperience, Hathaway assigns Mitch to lead the team due to his fresh and inventive ideas, hoping that he will remind Chris of how he used to be., can you guess it ?
Ans: "Ick" Ikagami
