Exam AWS Certified Alexa Skill Builder - Specialty topic 1 question 36 discussion

An Alexa Skill Builder has created a taxi hiring skill. The skill needs to find out when the customer wants a taxi, where the customer is traveling from, and where the customer wants to go. The Builder is currently asking each question individually, in the following order:
"Where do you want to take a taxi from"
"Where do you want to take a taxi to"
"When do you need a taxi"
To ensure the voice interaction is flexible, how should this information be gathered regardless of the order in which the user provides it?
