Why might the author have decided to explain a scientific concept using a reference to a historical event?

Hi. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.

The author explained a scientific concept because he wanted readers to understand the meaning of that scientific concept, which would allow the reading of the text to be more convenient and efficient for the reader. The decision to explain the scientific concept through a historical event was to show how this concept fits into the real world. The use of the reference, on the other hand, was intended to extend the explanation by showing another application of the scientific concept, making it even more understandable.

the correct answer is option d. the nature of democracy. on november 19, 1863, president abraham lincoln delivered his famous gettysburg address in gettysburg, pennsylvania. in his speech, rather than focusing on details of the war (soldiers, casualties, aftermath of battle), lincoln invoked the very nature of democracy, that power ultimately comes from the people, when stating, “government of the people, by the people, for the people shall not perish”. these words mean that democracy is a government by the people (citizens) in which the supreme power is vested in the people and exercised directly by the people or by their elected representatives for the benefit of all citizens. the survival of democracy in the united states is one of the reasons why this speech so significant today.

different strategies reach different people based on their ability to understand the material. (from personal experience) when writing an argumentative essay write explaining the subject as though your audience never heard of it before and it is just being introduced, then explain why other people hate it also, afterward you would explain why that would be wrong. i hope that : )
