I believe the answer is: d. the shell and the skeleton
The shell and skeleton in architecture would act as the main foundation that support the weight of the whole building. The strength of shell skeleton would determine whether the building would collapse during natural disaster such as earthquakes.
Having crew members repeat back instructions to clarify what they have heard is one way to catch mistakes before they happen.
In our day-to-day life, we make our best decisions when we gather a lot of information. If we take the case of wildland fire fighting, we should be situationally aware to face the threat. We should know what’s going on around us—and should immediately share vital information about hazards with our supervisor and crew members in order to adopt safety measures and avoid mistakes. Situational awareness does not maintain an “off switch” when we are working near a fire.
It is somehow tempting to focus on what will be in front of us if we have got a specific task, but clarify to not forget to look up once in a while as there will be a lot going on over our head. When we look up we may encounter any number of potential hazards.

The greatest problem associated with detecting marijuana in urine is that it is difficult to determine when the individual actually used marijuana.
It was somehow succesful because the origins of the labor movement lay in the formative years of the American nation, when a free wage-labor market emerged in the artisan trades late in the colonial period. The earliest recorded strike occurred in 1768 when New York journeymen tailors protested a wage reduction. The formation of the Federal Society of Journeymen Cordwainers (shoemakers) in Philadelphia in 1794 marks the beginning of sustained trade union organization among American workers.
From that time on, local craft unions proliferated in the cities, publishing lists of “prices” for their work, defending their trades against diluted and cheap labor, and, increasingly, demanding a shorter workday. Thus a job-conscious orientation was quick to emerge, and in its wake there followed the key structural elements characterizing American trade unionism–first, beginning with the formation in 1827 of the Mechanics’ Union of Trade Associations in Philadelphia, central labor bodies uniting craft unions within a single city, and then, with the creation of the International Typographical Union in 1852, national unions bringing together local unions of the same trade from across the United States and Canada (hence the frequent union designation “international”). Although the factory system was springing up during these years, industrial workers played little part in the early trade union development. In the 19th century, trade unionism was mainly a movement of skilled workers.
