Technological choices

In some cases, the technological choices might have been less successful. Example of these are lead pipes, used in the antique and continued to be used in house connections until recently. water supply and sanitation systems need constant maintenance and adequate rehabilitation. This was already seen in the Roman aqueducts: calcium carbonate incrustation formed inside the conduits needed constant removal, while otherwise stopping the water flow. The same is true for the modern systems, the maintenance of them must be taken care of otherwise they do not function properly. The bigger problem is related to the need of constant replacement and fixing.

One long-term debatable issue has, and still is, what source to use, whether to use ground or surface water as raw water for community purposes. Surface water was needed to be used in bigger systems, but for smaller systems, ground water was commonly used. This is connected to the current question, how far is it economically possible to expand the systems. Once the systems expand other problems such as being over exposed are to be considered.

Today in the United States the poverty rate of the elderly is ______.
tester [92]

The correct answer is B. Increasing

Explanation:

In sociology, poverty occurs when an individual or a group of people are unable to pay for basic elements such as food, clothes, and housing and therefore basics need are not fulfilled or at least not completely satisfied. Poverty rates vary according to the country or zone, but also according to different groups in society. In the case of elderly, this is a group in society that is at risk of experiencing poverty due to lack of job opportunities, lack of saving and health issues that stop them from working. Because of this, it is estimated in the U.S. a decade ago around 9% of elderly people living in poverty and unfortunately, in the last years, this percentage has increased to around 15% mainly due to the economic recession the U.S. experienced during the 21st century along with programs and laws that have increased taxes. Therefore, today the poverty rate of the elderly in the United States is mainly increasing.

Answer: Construct validity

Explanation:

Construct validity is the degree to which a test is done to measure what it claims. Construct validity defines how well the test or experiment actually measures its claims and whether the operational definition of the variable reflect the true theoretical meaning of the concept being illustrated.
