The correct answer is D. unfamiliar with the geography and terrain.
The Continental Army, lead by George Washington, squared off with the British army during the American Revolution. During this time, the colonists were extremely unorganized, had little supplies, and was staffed by thousands of volunteers.
However the Continental Army did have an advantage in knowing the geography/climate. Considering the volunteer soldiers for the Continental Army lived in the 13 colonies (where the fighting took place) the geography and terrain was very familiar to them.

Not sure but hope what I know help a little...Slavery was “an unqualified evil to the negro, the white man, and the State,” said Abraham Lincoln in the 1850s. Yet in his first inaugural address, Lincoln declared that he had “no purpose, directly or indirectly, to interfere with slavery in the States where it exists.” He reiterated this pledge in his first message to Congress on July 4, 1861, when the Civil War was three months old.<span>Did You Know?When it took effect in January 1863, the Emancipation Proclamation freed 3.1 million of the nation's 4 million slaves.</span>
What explains this apparent inconsistency in Lincoln’s statements? And how did he get from his pledge not to interfere with slavery to a decision a year later to issue an emancipation proclamation? The answers lie in the Constitution and in the course of the Civil War. As an individual, Lincoln hated slavery. As a Republican, he wished to exclude it from the territories as the first step to putting the institution “in the course of ultimate extinction.”
The printing press
Movable type printing was introduced to Europe by Johann Gutenberg in the mid-15th century. This technological advance made it possible for a reformer like Martin Luther to spread his ideas widely and rapidly. While overall literacy rates were low at that time, it was common for people to gather for reading of the latest Reformation materials. Hundreds of thousands of copies of tracts written by Luther were printed and distributed -- as well as similar spread of ideas by publishing done by other reformers.
