Imagine you are a historian studying a journal written by a citizen living in East Berlin when the Berlin Wall was being constructed. Describe the process of interpreting the information

The correct answer to this open question is the following.

If I were a historian studying a journal written by a citizen living in East Berlin when the Berlin Wall was being constructed. My process of interpreting the information would be the following.

First and foremost, I have to make sure this is a valid and original document written by a citizen who lived in that time of the Berlin Wall, during the Cold War years.

Then, I would have to check other important valid sources as is the case of newspapers of that time, magazines, or even radio programs. Once checked, I would proceed to divide the most important arguments of events in the journal. I dive these into facts, mere opinions, quotes, or anecdotes. Then I would have a more complete scenario to try to understand what was real in the journal and what were opinions or judgments.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
