The feature allows users to post multiple-choice questions on their stories, and then followers can select the answer they think is correct.
What is cool is, those answering will be shown immediately if the answer is correct or not.
Instagram encourages users to use the feature to ask friends and followers multiple-choice questions, and see how well they know each other.
This is an additional feature to already existing stickers like; Questions, Poll, Music and Countdown.
You will need to update your Instagram app to the latest version to use the new feature.
