Think about the type of the value you're setting the "food" key to. Do you want to set it to the string "true"?

Here's a few hints:

  • you need to use your test in a conditional statement ("if") to control when the variable is set
  • the variable name should be simply "food" (you won't need "hash")
  • variable names and non-string values should not be enclosed in quotes
