QUES: Until mid-to-late adolescence, boys and girls show relatively little difference in drinking motives. Distinctions between the reasons for alcohol consumption of males and females begin to emerge around ages 1415; overall, boys tend to view drinking in a more social light than girls, who report on average a more frequent use of alcohol as a coping mechanism. The latter effect appears to shift in late adolescence and onset of early adulthood (1819 years of age); however, despite this trend, age tends to bring a greater desire to drink for pleasure rather than coping in both boys and girls.
Which gender reports most frequently using alcohol as a coping mechanism?

ANS: girls

QUES: Most clothing appears to have been made of animal skins, as indicated by finds of large numbers of bone and antler pins which are ideal for fastening leather. Wool cloth and linen might have become available during the later Neolithic, as suggested by finds of perforated stones which (depending on size) may have served as spindle whorls or loom weights. The clothing worn in the Neolithic Age might be similar to that worn by Otzi the Iceman, although he was not Neolithic (since he belonged to the later Copper age).
What evidence suggested that humans used animal products for clothing?

ANS: finds of large numbers of bone and antler pins

QUES: After several failed attempts, in 1930 the first aeroplane reached Bermuda. A Stinson Detroiter seaplane flying from New York, it had to land twice in the ocean: once because of darkness and again to refuel. Navigation and weather forecasting improved in 1933 when the Royal Air Force (then responsible for providing equipment and personnel for the Royal Navy's Fleet Air Arm) established a station at the Royal Naval Dockyard to repair (and supply replacement) float planes for the fleet. In 1936 Luft Hansa began to experiment with seaplane flights from Berlin via the Azores with continuation to New York City.
What improved thanks to the Royal Air Force in 1933?

ANS: Navigation and weather forecasting

QUES: Throughout the 20th century air defence was one of the fastest-evolving areas of military technology, responding to the evolution of aircraft and exploiting various enabling technologies, particularly radar, guided missiles and computing (initially electromechanical analog computing from the 1930s on, as with equipment described below). Air defence evolution covered the areas of sensors and technical fire control, weapons, and command and control. At the start of the 20th century these were either very primitive or non-existent.
The evolution of air defence was in answer to the evolution of what?

ANS:
aircraft
