How Carousel work in Learning?

Summary:

Hello All,

As we have new feature in Learning-

Under Me -Learning-Browse - Featured, Recommended, Categories tabs

In each tab , we can see the Carousel (say for tab-Recommended-The image carousel shows the five most recently recommended learning).

My question here is that-

1. five most recently recommended learning-Will it show "any learnings which have been recommended most times in overall learning"?
2. five most recently recommended learning-Will it show "learnings which have been recommended most times to the signed in learner"?
3. five most recently recommended learning-Will it show " learning in which more learners have enrolled in?" If this is the case, which type of learning- Required, Voluntary, Recommended?
