   A developer is writing a function that takes a list of numbers and returns a new list with each number doubled. The developer wants to avoid modifying the original list. Which programming paradigm naturally supports this approach?

   • AObject-oriented programming, using a class method to update the list.
   • BScripting, using a global variable to store the result.
   • CFunctional programming, using a map function that returns a new list.
   • DProcedural programming, using a loop to modify the list in place.

   • CUse a class with a method that updates the order list.
   • DUse a map function to create a new list of discounted orders, then a reduce function to sum the totals.

   A developer is debugging a program that behaves differently in production than in development. The production environment is a different operating system. The developer suspects a language feature that behaves differently across platforms. Which type of language is more likely to cause this issue?

   • AA scripting language, because it is interpreted and may use system commands.
   • BAny language, because platform differences can affect behavior regardless of compilation.
   • CAn interpreted language, because the interpreter may have platform-specific behavior.
   • DA compiled language, because the compiled binary is tied to the target platform.
