Final answer:
When variables are missing in a conditional question, it becomes difficult to evaluate the condition and determine the outcome accurately. All relevant variables and information are needed to make an informed decision.
Step-by-step explanation:
When you are missing variables to complete a conditional question, it means that you don't have all the necessary information to evaluate the condition and determine the outcome. This can make it difficult to answer the question accurately.
For example, if the conditional statement is 'If it is raining and the temperature is below 32 degrees Fahrenheit, then it will snow,' but you don't know the current temperature, you cannot determine if it will snow or not.
In order to complete a conditional question, you need all the relevant variables and information provided to make an informed decision.
