Which of the following is the final step in bisecting a line segment? keeping the compass at the same width, place the compass on the other endpoint and swing arcs on either side so that they intersect the first two arcs created. mark the intersection points of the arcs, and draw a line through those two points. place the compass on one of the endpoints, and open the compass to a distance more than halfway across the segment. swing an arc on either side of the segment.

The truth is that any source can be the best source for some kind of research. as an example, if you were to write an essay about the credibility of wikipedia, would you avoid citing wikipedia? clearly not. as we know, the president of the united states jumps on twitter all the time. if you’re writing about trump, what better source can there be? it is, quite literally, an original historical document. the same would be true if you were writing about the events of the moderately recent revolutions in egypt and syria. what better source than someone who is right there in the thick of things? clearly you would have to contextualize the source as at least moderately unverified in most such cases.
