QUES: Typical use of the various technologies described above include calling or conferencing on a one-on-one, one-to-many or many-to-many basis for personal, business, educational, deaf Video Relay Service and tele-medical, diagnostic and rehabilitative use or services. New services utilizing videocalling and videoconferencing, such as teachers and psychologists conducting online sessions, personal videocalls to inmates incarcerated in penitentiaries, and videoconferencing to resolve airline engineering issues at maintenance facilities, are being created or evolving on an ongoing basis.
What is a common use of conferencing technology?

ANS: tele-medical

QUES: In 1910, over 2 million children in the same age group were employed in the United States. This included children who rolled cigarettes, engaged in factory work, worked as bobbin doffers in textile mills, worked in coal mines and were employed in canneries. Lewis Hine's photographs of child labourers in the 1910s powerfully evoked the plight of working children in the American south. Hines took these photographs between 1908 and 1917 as the staff photographer for the National Child Labor Committee.
Where was photographer Lewis Hine employed?

ANS: National Child Labor Committee

QUES: Some alloys occur naturally, such as electrum, which is an alloy that is native to Earth, consisting of silver and gold. Meteorites are sometimes made of naturally occurring alloys of iron and nickel, but are not native to the Earth. One of the first alloys made by humans was bronze, which is made by mixing the metals tin and copper. Bronze was an extremely useful alloy to the ancients, because it is much stronger and harder than either of its components. Steel was another common alloy. However, in ancient times, it could only be created as an accidental byproduct from the heating of iron ore in fires (smelting) during the manufacture of iron. Other ancient alloys include pewter, brass and pig iron. In the modern age, steel can be created in many forms. Carbon steel can be made by varying only the carbon content, producing soft alloys like mild steel or hard alloys like spring steel. Alloy steels can be made by adding other elements, such as molybdenum, vanadium or nickel, resulting in alloys such as high-speed steel or tool steel. Small amounts of manganese are usually alloyed with most modern-steels because of its ability to remove unwanted impurities, like phosphorus, sulfur and oxygen, which can have detrimental effects on the alloy. However, most alloys were not created until the 1900s, such as various aluminium, titanium, nickel, and magnesium alloys. Some modern superalloys, such as incoloy, inconel, and hastelloy, may consist of a multitude of different components.
What adds desired impurities to modern steel?

ANS: unanswerable

QUES: 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.
Who complained about how Kerry ran the State Dept?

ANS:
Career State Department officials
