How does John DiConsiglio organize the text in "Disease Central," the supplemental text in When Birds Get Flu, to present the central idea?

He presents the central idea first.
He concludes with the central idea.
He presents the central idea in the middle.
He summarizes the central idea with a quote.

What character trait does penelope demonstrate when she calls for the suitors to hold a contest? what other character has a similar trait? she demonstrates cleverness, like odysseus does when he tricks and overcomes foes. she demonstrates hospitality, like the phaeacians do when odysseus lands on their island. she demonstrates a lack of confidence, like telemachus does when he fails to kick out the suitors. she demonstrates a lack of self control, like odysseus’s men do when they slaughter helios’s cattle.

What central idea does this passage develop? the impact of fate the integrity of leaders the ruthlessness of power the importance of friendship

I’ve given a lot of thought to what one of them should be, and the answer seems clear.
