You won't need to embed any data in your function, the system will pass the data to you in the argument.

Also, they instructions say the the function "takes a single argument", so you won't need the gather (splat) operator.

That single argument will be the dictionary you'll count the teachers in. it will have a structure like the sample shown in the comment, but it won't be exactly the same as the sample.
