Quick Read. Capital-city failure is unusually consequential because the city may contain both ordinary urban systems and national command systems. A local failure can therefore propagate into the state.
Eight failure channels
Power: grid failure disables cooling, pumps, communications, hospitals and offices.
Water: scarcity or treatment failure becomes household, health and political stress.
Transport: blocked bridges, rail or roads shrink the effective labour and command market.
Government: administrative paralysis delays decisions far outside the city.
Security: conflict can fragment mobility and service territories.
Communications: information loss makes coordination itself fail.
Supply: port, airport or corridor disruption interrupts food, fuel and specialist inputs.
Compound failure: the dangerous case is two or more channels interacting.
The substitution test
For every capital ask: what fails first, what depends on it, what substitute exists, how much capacity does that substitute have, and how long can it operate? This converts resilience from a slogan into a graph.

Take one question further
The same learning habit can travel across subjects, while each subject keeps its own methods. These routes help you notice a difficulty, understand one part of it, and return to something you can do.
Try it without the guide: Choose one word you already know. Close the guide and use it in a new sentence. Explain why it fits; try another context tomorrow.
A piece of writing has ideas, but the reader loses the thread.
Try it without the guide: Choose one short paragraph. Read the relevant explanation, close it, and revise the paragraph. Ask someone to tell you what happened and why.
The Mathematics seems familiar, but marks still disappear.
Try it without the guide: For a Secondary 4 A-Math question you have attempted, locate the first uncertain line. Repair that step, then try a comparable question without the worked answer.
A Science fact is remembered, but the explanation is incomplete.
Try it without the guide: Choose a familiar Primary Science example. Explain the evidence, the idea and the result without notes. Then change one condition and explain your prediction.
Try it without the guide: Take one claim. Find the source best placed to support it, note its date, and state what remains uncertain. Return to your original question.
There is plenty of help, but independence is hard to see.
Try it without the guide: Choose one small task the child has practised. Agree on a calm, brief attempt without prompts. Use what happens to choose one next step, then stop.
