Problem: Wide-ringed wood is often called "second-growth", because the growth of the young timber in open stands after the old trees have been removed is more rapid than in trees in a closed forest, and in the manufacture of articles where strength is an important consideration such "second-growth" hardwood material is preferred. This is particularly the case in the choice of hickory for handles and spokes. Here not only strength, but toughness and resilience are important. The results of a series of tests on hickory by the U.S. Forest Service show that:
What term is sometimes used for wood with wide rings?
The answer is the following: second-growth

Problem: An influx of interstate and overseas migrants, particularly Irish, German and Chinese, saw the development of slums including a temporary "tent city" established on the southern banks of the Yarra. Chinese migrants founded the Melbourne Chinatown in 1851, which remains the longest continuous Chinese settlement in the Western World. In the aftermath of the Eureka Stockade, mass public support for the plight of the miners resulted in major political changes to the colony, including changes to working conditions across local industries including mining, agriculture and manufacturing. The nationalities involved in the Eureka revolt and Burke and Wills expedition gave an indication of immigration flows in the second half of the nineteenth century.
During the second half of what century did the Burke and Wills expedition give an indication of immigration flows?
The answer is the following: second half of the nineteenth century

Problem: Chronic obstructive pulmonary disease can coexist with asthma and can occur as a complication of chronic asthma. After the age of 65 most people with obstructive airway disease will have asthma and COPD. In this setting, COPD can be differentiated by increased airway neutrophils, abnormally increased wall thickness, and increased smooth muscle in the bronchi. However, this level of investigation is not performed due to COPD and asthma sharing similar principles of management: corticosteroids, long acting beta agonists, and smoking cessation. It closely resembles asthma in symptoms, is correlated with more exposure to cigarette smoke, an older age, less symptom reversibility after bronchodilator administration, and decreased likelihood of family history of atopy.
What are the principles of management for asthma and COPD?
The answer is the following: corticosteroids, long acting beta agonists, and smoking cessation

Problem: The winner, Taira no Kiyomori, became an imperial advisor, and was the first warrior to attain such a position. He eventually seized control of the central government, establishing the first samurai-dominated government and relegating the Emperor to figurehead status. However, the Taira clan was still very conservative when compared to its eventual successor, the Minamoto, and instead of expanding or strengthening its military might, the clan had its women marry Emperors and exercise control through the Emperor.
How did the Taira clan expand power?
The answer is the following:
had its women marry Emperors
