Answer:
To alter behaviors, to influence public opinion, or to raise awareness about an issue.
Explanation:
The answer is one and four.
1 and 4 are generally facts about his life and what he did.
2 and 3 are minor details rather than central ideas.
The conclusion of the excerpt is that the narrator does not have facts and that all information provided is only suggestive that the referenced persons seem to have taken advantage of insider information.
The central idea of this excerpt hence is that there is a red flag being raised on the possibility that certain persons may have breached ethical principles that prohibit insider trading.
<h3>
What is a central idea?</h3>
A central idea is the dominant thought to which all other parts of a text relate to.
<h3>What is insider trading?</h3>
Apart from its connection to fraud or breach of fiduciary responsibility, insider trading per se refers to making financial investments based on knowledge that is unknown to others.
Such behaviors obviously should be regarded as ethically reprehensible since they adversely impact other people.
<h3>How does insider trading hurt others?</h3>
Insider trading reduces investor returns by negatively affecting market liquidity and raising transaction costs.
Additionally, because so many individuals have a stake in the financial markets—roughly half of American households own stocks directly or indirectly—most Americans are harmed by this activity.
