Problem: Please answer a question about the following article about Immunology:
The body's capability to react to antigen depends on a person's age, antigen type, maternal factors and the area where the antigen is presented. Neonates are said to be in a state of physiological immunodeficiency, because both their innate and adaptive immunological responses are greatly suppressed. Once born, a child's immune system responds favorably to protein antigens while not as well to glycoproteins and polysaccharides. In fact, many of the infections acquired by neonates are caused by low virulence organisms like Staphylococcus and Pseudomonas. In neonates, opsonic activity and the ability to activate the complement cascade is very limited. For example, the mean level of C3 in a newborn is approximately 65% of that found in the adult. Phagocytic activity is also greatly impaired in newborns. This is due to lower opsonic activity, as well as diminished up-regulation of integrin and selectin receptors, which limit the ability of neutrophils to interact with adhesion molecules in the endothelium. Their monocytes are slow and have a reduced ATP production, which also limits the newborn's phagocytic activity. Although, the number of total lymphocytes is significantly higher than in adults, the cellular and humoral immunity is also impaired. Antigen-presenting cells in newborns have a reduced capability to activate T cells. Also, T cells of a newborn proliferate poorly and produce very small amounts of cytokines like IL-2, IL-4, IL-5, IL-12, and IFN-g which limits their capacity to activate the humoral response as well as the phagocitic activity of macrophage. B cells develop early during gestation but are not fully active.
What are the four factors that determine how the body reacts to an antigen?
A: person's age, antigen type, maternal factors and the area
Problem: Please answer a question about the following article about John Kerry:
In the State Department, Kerry quickly earned a reputation "for being aloof, keeping to himself, and not bothering to read staff memos." Career State Department officials have complained that power has become too centralized under Kerry's leadership, which slows department operations when Kerry is on one of his frequent overseas trips. Others in State describe Kerry as having "a kind of diplomatic attention deficit disorder" as he shifts from topic to topic instead of focusing on long-term strategy. When asked whether he was traveling too much, he responded, "Hell no. I'm not slowing down." Despite Kerry's early achievements, morale at State is lower than under Hillary Clinton according to department employees. However, after Kerry's first six months in the State Department, a Gallup poll found he had high approval ratings among Americans as Secretary of State. After a year, another poll showed Kerry's favorability continued to rise. Less than two years into Kerry's term, the Foreign Policy Magazine's 2014 Ivory Tower survey of international relations scholars asked, "Who was the most effective U.S. Secretary of State in the past 50 years?"; John Kerry and Lawrence Eagleburger tied for 11th place out of the 15 confirmed Secretaries of State in that period.
What was the complaint about how Kerry ran the State Dept?
A: power has become too centralized under Kerry's leadership, which slows department operations when Kerry is on one of his frequent overseas trips
Problem: Please answer a question about the following article about Egypt:
The canal is 193.30 km (120.11 mi) long, 24 m (79 ft) deep and 205 metres (673 ft) wide as of 2010. It consists of the northern access channel of 22 km (14 mi), the canal itself of 162.25 km (100.82 mi) and the southern access channel of 9 km (5.6 mi). The canal is a single lane with passing places in the "Ballah By-Pass" and the Great Bitter Lake. It contains no locks; seawater flows freely through the canal. In general, the canal north of the Bitter Lakes flows north in winter and south in summer. The current south of the lakes changes with the tide at Suez.
How many locks are contained in Suez Canal?
A: no locks
Problem: Please answer a question about the following article about London:
Among other inhabitants of London are 10,000 foxes, so that there are now 16 foxes for every square mile (2.6 square kilometres) of London. These urban foxes are noticeably bolder than their country cousins, sharing the pavement with pedestrians and raising cubs in people's backyards. Foxes have even sneaked into the Houses of Parliament, where one was found asleep on a filing cabinet. Another broke into the grounds of Buckingham Palace, reportedly killing some of Queen Elizabeth II's prized pink flamingos. Generally, however, foxes and city folk appear to get along. A survey in 2001 by the London-based Mammal Society found that 80 percent of 3,779 respondents who volunteered to keep a diary of garden mammal visits liked having them around. This sample cannot be taken to represent Londoners as a whole.
What type of animal belonging to Queen Elizabeth II was killed by an intruding fox on the Buckingham Palace grounds?
A:
pink flamingos
