Read the sentence. the british defeat of the mahdist forces at omdurman finally brought an end to the shameful and horrific slave trade. this sentence does not maintain a formal style and tone because it uses casual language. is completely objective. uses charged language. is a choppy sentence.

The answer to your question would be that the sentence does not mantain a formal style and tone because it uses charged language.  The statement is not an objective fact, it is charged with subjective language instead ("shameful", "horrific").

Formal writing employs impersonal and precise language. Writing formally and objectively requires a writer to write without sharing his personal point of view. What is more, formal and objective writing should also avoid the use of the first person or the personal point of view.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
