question: 2
what can be used to teach karel to turn right?
functions
variables
dog treats
karel can already turn right

Explanation:

In programming with Karel (a programming - like environment for teaching basic programming concepts), functions can be defined to make Karel perform actions such as turning right. Variables are used for storing values, dog treats are irrelevant in a programming context, and Karel doesn't have an inherent ability to turn right without programming it using functions.

Answer:

A. Functions
