Microsoft Azure AI Fundamentals — Question 23

You have a dataset that contains information about taxi journeys that occurred during a given period.
You need to train a model to predict the fare of a taxi journey.
What should you use as a feature?

Answer options

• A. the number of taxi journeys in the dataset
• B. the trip distance of individual taxi journeys
• C. the fare of individual taxi journeys
• D. the trip ID of individual taxi journeys

Correct answer: B

Explanation

The correct answer is B because the trip distance directly influences the fare calculation in taxi journeys. Options A and D are not relevant as they do not provide direct information about the fare, while option C would be the outcome rather than a predictive feature.
