Summarise a Complex Argument You Need to Engage With

Reading a complex argument and then reacting to it is not the same as understanding it. This produces a fair summary: the central claim, the strongest form of the main supporting arguments, the assumption it depends on most, and how the author handles the obvious counterargument. A map before the critique.

**Summarise** the argument in {ARGUMENT_SOURCE} for someone who needs to engage with it critically.
1. State the central claim in one sentence
2. List the three to five main supporting arguments or premises, in the strongest form in which they appear
3. Identify the one assumption the argument depends on most heavily
4. Note the most significant counterargument the author anticipates, and how they respond to it
</task>
