Remember: A function is a named bundle of lines. Def writes it down, a call runs it, and a parameter is a blank you fill in.
Read and answer
Read the story, then answer.
The finaleBo's finale is a spin, a clap and a bow, and it happens three times in the show. Mina typed the three moves three times and had nine lines. Then she wanted a deeper bow, so she had to fix it three times. Ms. Ola says a function is a bundle of lines with a name. Mina writes def cheer(): and pushes the moves in under it. When she runs it, Bo stands still, because def only writes the recipe down. To make Bo cheer, Mina calls the function by writing cheer() on a line of its own. Later she makes a function with a blank, a parameter: greet("Bo") says hi Bo, and greet("Teo") says hi Teo.

Put Mina's steps in order.

Mina teaches Bo to cheer
1Bo does nothing, because def only writes the recipe down Def writes the recipe, and only a call runs it.
2called Def writes a function down. A call runs it.
3True Def is the recipe, and the call is the cooking.
4line 5 Line 5 is cheer() on a line of its own, not pushed in. Line 1 only writes the function.
5Three times Each call runs the function once, so three calls give three cheers.
6False The bow is written once inside cheer, so one fix changes all three cheers.
71-B, 2-A, 3-D, 4-C Def writes, a call runs, a parameter is a blank, and pushed-in lines are inside the function.
84, 3, 2, 1 First the recipe is written, then it is called, and only then does Bo cheer when the program runs.
9hi Teo Same recipe, different input, different result.
10parameter A parameter is a blank you fill in each time you call the function.
11No line calls dance() Nobody called dance, so it never ran. Add a line dance() on its own.
