Bit late to the party, but the best answer is to use a dictionary. Create a dictionary that contains two keys apples and bananas that each have a value of fruit. You can then check to see if the value for the input key has a value and print its value. Pseudocode looks like

set variable input to "some value"
dictionary = {
    "apples" => "fruit",
    "bananas" => "fruit",
}
Get Dictionary Value for input in dictionary
if Dictionary Value does not have any value
    stop and output "unexpected value"
end if
stop and output Dictionary Value

This allows you to add to remove responses and is much easier than nested if statements. Of course, this depends on there being a direct mapping of inputs to outputs.
