You are probably using a student language instead of #lang racket
To fix put "#lang racket" at the top of your program
or click the language button at the bottom-left of your Dr.Racket window
and pick a non-teaching language.

However, I tried an example:
(cons 1 2)
And get this error message:
cons: second argument must be a list, but received 1 and 2
The example here:
2 matches
