Passage Summary: People are naturally wired to help others, but because being 'moral' requires thinking and following specific rules, just acting on instinct doesn't always count as a moral act.

Conclusion: The inherent human tendency toward altruism actually prevents certain altruistic acts from being classified as moral.

Reasoning: Morality requires that behavior be guided by reason and a conscious intent to follow a formal moral code, rather than just natural impulse.

Analysis: To identify the conclusion in this argument, look for the claim that the other statements are working to support. The first sentence presents a counterintuitive claim about natural altruism, while the subsequent sentences provide the necessary criteria for morality to explain that claim. You can tell the first sentence is the conclusion because the points about 'reason' and 'moral codes' function as the evidence needed to justify why instinctual altruism falls short of the moral finish line. It’s a classic LSAT structure where the first sentence is the 'what' and the rest is the 'why.'
