One difference between the long run and the short run in a perfectly competitive industry is that:

economic profits in the long run are always greater than they are in the short run.

economic profits in the short run are always greater than they are in the long run.

The coming of the Green Knight

Now I will say no more of the service, but that ye may know there was no lack, for there drew near a venture that the folk might well have left their labour to gaze upon. As the sound of the music ceased, and the first course had been fitly served, there came in at the hall door one terrible to behold, of stature greater than any on earth; from neck to loin so strong and thickly made, and with limbs so long and so great that he seemed even as a giant. And yet he was but a man, only the mightiest that might mount a steed; broad of chest and shoulders and slender of waist, and all his features of like fashion; but men marvelled much at his colour, for he rode even as a knight, yet was green all over.

The fashion of the knight

For he was clad all in green, with a straight coat, and a mantle above; all decked and lined with fur was the cloth and the hood that was thrown back from his locks and lay on his shoulders. Hose had he of the same green, and spurs of bright gold with silken fastenings richly worked; and all his vesture was verily green. Around his waist and his saddle were bands with fair stones set upon silken work, 'twere too long to tell of all the trifles that were embroidered thereon—birds and insects in gay gauds of green and gold.

What is the best description of the mood created by the setting of this passage?

A. Humorous, because the knight was not invited to the party.

B. Peaceful, because the knight brought a sense of calm to the party.

C. Threatening, because the knight showed up suddenly at the party.

D. Uplifting, because the knight who showed up is interesting and glamorous.
