' He was terrified, for
he had never expected to find empty space underneath the world.
But his wife was filled with curiosity.'
Primary Research: Primary research usually means a primary source. For example, Primary Research can be interviewing someone, conducting research. Other examples can be observations, case studies, surveys, experiments etc. The individual directly collects information from the experiment.
Secondary Research relies on secondary sources for example using a book to prepare for a report. Secondary data can be books, articles published, statistical data, reports, and case studies.
So basically, primary research is direct contact to collect the data and secondary is using other sources rather than directly getting the information from the source. Hope this helps.
Answer:
The central idea of Lincoln's speech was to show the American public that the nation must stay united and tell Southerners that secession was illegal. Lincoln says, "Plainly the central idea of secession is the essence of anarchy." Through this statement, he demonstrates that the Southern states' attempt to separate from the Union is a breach of law and order. He also argues that the US Constitution is permanent and cannot be dissolved. There are no terms in the Constitution that allow the dissolution of its government:
Perpetuity is implied, if not expressed, in the fundamental law of all national governments. It is safe to assert that no government proper ever had a provision in its organic law for its own termination.
Lincoln also reassures Southerners that his Republican administration would not interfere in matters related to slavery and its laws:
I have no purpose, directly or indirectly, to interfere with the institution of slavery in the States where it exists. I believe I have no lawful right to do so, and I have no inclination to do so.
He tries to calm the anxious Southerners by telling them that he is committed to upholding their states' rights:
. . . the property, peace, and security of no section are to be in any wise endangered by the now incoming Administration. I add, too, that all the protection which, consistently with the Constitution and the laws, can be given will be cheerfully given to all the States when lawfully demanded, for whatever cause—as cheerfully to one section as to another.
It's mostly written in 1st person if I remember correctly.
