You are advised to implement an 80/20 splitwith training and test utterances. This means that 80% of new utterances harvested from the conversation logs should be used as intent training utterances and 20% for testing.
Why is this a good practice?

• A.By performing an 80/20 split, you are randomizing which data is added to the utterances.
• B.By keeping 20% for testing, you are able to test the model with data on which it has not been specifically trained.
• C.Adding 100% of user phrases to the intent wouldoverload the model.
• D.Batch testing works more efficiently when there is a ratio of one test utterance for every five training utterances.

You have a skill for ordering pizzas. In your experience, you have found that 95% of your customers want a regular crust and just 5% prefer gluten-free crust. Because so few people are likely to want a gluten-free crust, you don't want to prompt for that option, but you do want to make it available.
Assuming you already have a composite bag entity that contains a PizzaCrust entity that has the values
"regular" and "gluten free", what would be the simplest way to have your skill enable a user to order a pizza with a gluten-free crust without the skill prompting the user for that option?

• A.For the PizzaCrust entity item, set the Extract With property to reference an entity with the single value
  "gluten free".
• B.In the composite bag, set the PizzaCrust entity item's Prompt for Value property to False. Then, once the the composite bag is resolved, check if the PizzaCrust entity has a value. If it doesn't, set its value to
  "regular".
• C.Don't set a prompt for the PizzaCrust entity item.
• D.Don't set a prompt for the PizzaCrust entity item and set the Out of Order Extraction property to True.
