Article: Asthma is the result of chronic inflammation of the conducting zone of the airways (most especially the bronchi and bronchioles), which subsequently results in increased contractability of the surrounding smooth muscles. This among other factors leads to bouts of narrowing of the airway and the classic symptoms of wheezing. The narrowing is typically reversible with or without treatment. Occasionally the airways themselves change. Typical changes in the airways include an increase in eosinophils and thickening of the lamina reticularis. Chronically the airways' smooth muscle may increase in size along with an increase in the numbers of mucous glands. Other cell types involved include: T lymphocytes, macrophages, and neutrophils. There may also be involvement of other components of the immune system including: cytokines, chemokines, histamine, and leukotrienes among others.

Question: In what ways do airways change?
Ans: an increase in eosinophils and thickening of the lamina reticularis

Article: Some bird species undertake shorter migrations, travelling only as far as is required to avoid bad weather or obtain food. Irruptive species such as the boreal finches are one such group and can commonly be found at a location in one year and absent the next. This type of migration is normally associated with food availability. Species may also travel shorter distances over part of their range, with individuals from higher latitudes travelling into the existing range of conspecifics; others undertake partial migrations, where only a fraction of the population, usually females and subdominant males, migrates. Partial migration can form a large percentage of the migration behaviour of birds in some regions; in Australia, surveys found that 44% of non-passerine birds and 32% of passerines were partially migratory. Altitudinal migration is a form of short distance migration in which birds spend the breeding season at higher altitudes elevations and move to lower ones during suboptimal conditions. It is most often triggered by temperature changes and usually occurs when the normal territories also become inhospitable due to lack of food. Some species may also be nomadic, holding no fixed territory and moving according to weather and food availability. Parrots as a family are overwhelmingly neither migratory nor sedentary but considered to either be dispersive, irruptive, nomadic or undertake small and irregular migrations.

Question: What is most often triggered by temperature changes?
Ans: Altitudinal migration

Article: Kathmandu had only one western-style restaurant in 1955. A large number of restaurants in Kathmandu have since opened, catering Nepali cuisine, Tibetan cuisine, Chinese cuisine and Indian cuisine in particular. Many other restaurants have opened to accommodate locals, expatriates, and tourists. The growth of tourism in Kathmandu has led to culinary creativity and the development of hybrid foods to accommodate for tourists such as American chop suey, which is a sweet-and-sour sauce with crispy noodles with a fried egg commonly added on top and other westernized adaptations of traditional cuisine. Continental cuisine can be found in selected places. International chain restaurants are rare, but some outlets of Pizza Hut and KFC have recently opened there. It also has several outlets of the international ice-cream chain Baskin-Robbins

Question: Along with locals and tourists, who eats at Kathmandu's restaurants?
Ans: expatriates

Article: The American bison is a large bovid which inhabited much of western North America prior to the 1800s, living on the prairies in large herds. However, the vast herds of bison attracted market hunters, who killed dozens of bison for their hides only, leaving the rest to rot. Thousands of these hunters quickly eliminated the bison herds, bringing the population from several million in the early 1800s to a few hundred by the 1880s. Conservation efforts have allowed the population to increase, but the bison remains near-threatened.

Question: What did hunter do with the rest of the bison?
Ans:
leaving the rest to rot
