QUES: Tourism is considered another important industry in Nepal. This industry started around 1950, as the country's political makeup changed and ended the country's isolation from the rest of the world. In 1956, air transportation was established and the Tribhuvan Highway, between Kathmandu and Raxaul (at India's border), was started. Separate organizations were created in Kathmandu to promote this activity; some of these include the Tourism Development Board, the Department of Tourism and the Civil Aviation Department. Furthermore, Nepal became a member of several international tourist associations. Establishing diplomatic relations with other nations further accentuated this activity. The hotel industry, travel agencies, training of tourist guides, and targeted publicity campaigns are the chief reasons for the remarkable growth of this industry in Nepal, and in Kathmandu in particular.
When did construction on the Tribhuvan Highway begin?

QUES: Other microscopic procedures may also aid in identifying infectious agents. Almost all cells readily stain with a number of basic dyes due to the electrostatic attraction between negatively charged cellular molecules and the positive charge on the dye. A cell is normally transparent under a microscope, and using a stain increases the contrast of a cell with its background. Staining a cell with a dye such as Giemsa stain or crystal violet allows a microscopist to describe its size, shape, internal and external components and its associations with other cells. The response of bacteria to different staining procedures is used in the taxonomic classification of microbes as well. Two methods, the Gram stain and the acid-fast stain, are the standard approaches used to classify bacteria and to diagnosis of disease. The Gram stain identifies the bacterial groups Firmicutes and Actinobacteria, both of which contain many significant human pathogens. The acid-fast staining procedure identifies the Actinobacterial genera Mycobacterium and Nocardia.
What is Geimsa stain?

ANS: a dye

QUES: American Idol became the most expensive series on broadcast networks for advertisers starting season four, and by the next season, it had broken the record in advertising rate for a regularly scheduled prime-time network series, selling over $700,000 for a 30-seconds slot, and reaching up to $1.3 million for the finale. Its ad prices reached a peak in season seven at $737,000. Estimated revenue more than doubled from $404 million in season three to $870 million in season six. While that declined from season eight onwards, it still earned significantly more than its nearest competitor, with advertising revenue topping $800 million annually the next few seasons. However, the sharp drop in ratings in season eleven also resulted in a sharp drop in advertising rate for season twelve, and the show lost its leading position as the costliest show for advertisers. By 2014, ad revenue from had fallen to $427 million where a 30-second spot went for less than $300,000.
How much did advertisers spend for a 30 second ad spot during American Idol in 2014? 

ANS: less than $300,000

QUES: In some countries, law enforcement uses race to profile suspects. This use of racial categories is frequently criticized for perpetuating an outmoded understanding of human biological variation, and promoting stereotypes. Because in some societies racial groupings correspond closely with patterns of social stratification, for social scientists studying social inequality, race can be a significant variable. As sociological factors, racial categories may in part reflect subjective attributions, self-identities, and social institutions.
Why is using racial categorization for profiling often criticized? 

ANS:
perpetuating an outmoded understanding of human biological variation
