The correct answer is <em><u>option A.</u></em> Porter is writing <em><u>social history</u></em> because he is focusing on lives of large numbers of ordinary people. He is examining letters, journal entries, autobiographies and newspapers from that time to see how the fear of the disease affected the lives of ordinary people. Porter is trying to recollect data from that time and put together a piece that describes how society was affected by the influenza pandemic, which was a consequence of World War I, an historic event that shaped and changed many societies, specially the ones from Europe.
Answer:
Prices are often volatile due to inelastic demand. e.g if there is a ‘good harvest’, supply will increase and there will be a fall in the price of primary products. However, because demand is inelastic, this would lead to a fall in revenue.

The volatile price of coffee – can make planning difficult.
Supply can also be volatile due to weather and disease. For agricultural crops, there is always a risk of crop failure, which could cause economic hardship in one particular year.
Limited resources. One day developing economies may run out of its finite primary products, e.g. precious metals could become scarce. Without diversification, this would leave the economy with a void.
Discourages investment in other aspects of the economy. Concentrating on primary products does not always help the long-term development of an economy because it can contribute towards a lack of investment in other aspects such as education and industrial production. Comparative advantage can change over time. It’s important to not just look at the present comparative advantage, but prospects for next 10 or 20 years.
There is a low-income elasticity of demand for primary products. With a rise in global income, there is a proportionately smaller percentage rise in demand for primary products. (agricultural products tend to be income inelastic). Therefore, if you produce primary products, you may see lower rates of economic growth than countries who produce manufacturing goods – which are more income elastic. The Prebisch-Singer hypothesis suggests that countries who concentrate on primary products are vulnerable to a declining terms of trade.

The answer is "Authenticity".
Authenticity is the characteristic of something having been given by an approved source. This idea incorporates non-revocation, which is the failure of a gathering to deny or challenge the validation of a collaboration. Authentication in non-repudiable connections gives evidence that these cooperations are remarkably connected to an approved source.
For instance, a client will most likely be unable to get to a non-repudiable document after its receipt without likewise producing a record of this entrance.
Answer: Complexity
Explanation: The nervous system is an essential and integral part of an individual or animal which aids the receipt and transmission of sensory information from and to other parts of the body. In the scenario above, the complex nature of the nervous system which enables it to codify more than one sensory information at a time is highlighted, It receives and peocesses different sensory signals simultaneously, transmitting received signals or stimulus to the brain to act on. The complexity of the nervous is demonstrated in Ashley's ability to talk on phone, type on a computer and hand documents to colleagues simultaneously.
