The main reason would be because so many of them had already died fighting against the British.
In general, this statement is true in the sense that Truman was a pragmatic leader. He of course came into office because of FDR's death, so he had great shoes to fill. Yet he did so with great poise.
Manifest Destiny basically mean, "EVERYONE MOVE TO THE WEST NOW!" But with no slaves, how would they create farms to maintain themselves? Easy: expand slavery. However, this was battled against by several sources to create the Compromise of 1850. The compromise delayed the Civil War, despite politicians knowing it will eventually happen. It bought them time-- that was important! Other new states like Nebraska and Kansas were allowed to allow slavery or not. This eventually grew to where the North had no slavery and the South did, which lead to the Civil War.
Correct answer: method or methods
"Touch typing" means to use a typewriter keyboard (or today, computer keyboard) without looking at the keys. The typist has a "touch" or "feel" for where all the keys are and can type more quickly by not needing visual confirmation of the keys they are striking as they type. I'm touch typing as I write this answer by the way -- I had a very good (and very fussy) keyboard instructor back in high school who drilled us over and over again in learning our keystrokes.
The practice of touch typing is sometimes credited to Frank Edward McGurrin, who was a court stenographer in Salt Lake City, Utah, and also taught typing classes. He won a typing contest held in Cincinnati in 1888 using his method. He developed his method while serving as a law office clerk in Grand Rapids, Michigan. He said of those early days of his career: "Before the end of the year 1878 I could write upwards of 90 words a minute in new matter without looking at the keyboard."
