Method. Describe each situation in four steps: (1) what happened, (2) what one family alone could have done, (3) what the community did, (4) the difference it made. Three or four situations are enough. Draw them as panels if you prefer, with one sentence under each.
Sample answers
What to write in your conclusion: in every one of these, the same pattern appears — a problem too big for one family, solved by people who expected nothing in return, and a duty accepted rather than a payment received. As the chapter puts it, communities exist because “all families and individuals within the community have specific duties to perform”, and because “everyone depends on a number of other people and communities”.
If you draw it: four panels work well — the problem, people gathering, the work being done together, the result. Look at the photographs on page 145 of the textbook for the idea: an entire hillside of people digging trenches, walking to the site with their own tools, and, at the end, a pond full of water where a bare slope used to be.
