QUES: The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety. Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, can protect against allergies and autoimmune diseases. The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans. One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not. In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.
Dogs can act as a facilitator of what between human beings?

ANS: social interactions

QUES: In the early 1900s, James J. Hill of the Great Northern began promoting settlement in the Montana prairie to fill his trains with settlers and goods. Other railroads followed suit. In 1902, the Reclamation Act was passed, allowing irrigation projects to be built in Montana's eastern river valleys. In 1909, Congress passed the Enlarged Homestead Act that expanded the amount of free land from 160 to 320 acres (0.6 to 1.3 km2) per family and in 1912 reduced the time to "prove up" on a claim to three years. In 1916, the Stock-Raising Homestead Act allowed homesteads of 640 acres in areas unsuitable for irrigation.  This combination of advertising and changes in the Homestead Act drew tens of thousands of homesteaders, lured by free land, with World War I bringing particularly high wheat prices. In addition, Montana was going through a temporary period of higher-than-average precipitation. Homesteaders arriving in this period were known as "Honyockers", or "scissorbills." Though the word "honyocker", possibly derived from the ethnic slur "hunyak," was applied in a derisive manner at homesteaders as being "greenhorns", "new at his business" or "unprepared", the reality was that a majority of these new settlers had previous farming experience, though there were also many who did not.
What year was the Enlarged Homestead Act passed?

ANS: 1909

QUES: Town terraced houses for all social classes remained resolutely tall and narrow, each dwelling occupying the whole height of the building. This contrasted with well-off continental dwellings, which had already begun to be formed of wide apartments occupying only one or two floors of a building; such arrangements were only typical in England when housing groups of batchelors, as in Oxbridge colleges, the lawyers in the Inns of Court or The Albany after it was converted in 1802. In the period in question, only in Edinburgh were working-class purpose-built tenements common, though lodgers were common in other cities. A curving crescent, often looking out at gardens or a park, was popular for terraces where space allowed. In early and central schemes of development, plots were sold and built on individually, though there was often an attempt to enforce some uniformity, but as development reached further out schemes were increasingly built as a uniform scheme and then sold.
Well-off continental dwellings consisted of?

ANS: wide apartments occupying only one or two floors of a building

QUES: The Jamahiriya's radical direction earned the government many enemies. In February 1978, Gaddafi discovered that his head of military intelligence was plotting to kill him, and began to increasingly entrust security to his Qaddadfa tribe. Many who had seen their wealth and property confiscated turned against the administration, and a number of western-funded opposition groups were founded by exiles. Most prominent was the National Front for the Salvation of Libya (NFSL), founded in 1981 by Mohammed Magariaf, which orchestrated militant attacks against Libya's government, while another, al-Borkan, began killing Libyan diplomats abroad. Following Gaddafi's command to kill these "stray dogs", under Colonel Younis Bilgasim's leadership, the Revolutionary Committees set up overseas branches to suppress counter-revolutionary activity, assassinating various dissidents. Although nearby nations like Syria also used hit squads, Gaddafi was unusual in publicly bragging about his administration's use of them; in June 1980, he ordered all dissidents to return home or be "liquidated wherever you are."
What Libyan government official allegedly plotted to kill Gaddafi in 1978?

ANS:
head of military intelligence
