Predict the result
How can a set list your three favorite sports?
There can be more than one correct list.

Set up the model
Label the set with the capital letter S.
Put three distinct sport names inside braces.

Work the example
The source example lists hockey, basketball, and soccer.
Commas separate the elements.
That is one possible three-element set.
A different list of three favorite sports can also qualify.

Check the result
Now write a set T containing four small hand tools.
Take eight seconds to think before the answer appears.
[Eight-second silent pause to work; the answer remains hidden.]
One possible set contains a wrench, screwdriver, hammer, and pliers.
These are four distinct tools.

Interpret the result
A set’s listing order does not change which elements belong to it.
Use the original task and check that your result fits its meaning.
