What is the way Search Engines select what Meta Title and Description to show in SERP

This question has been around for quite long time. I suspect that Bing realizes that #seo specialists need some more clarification and shed some light on it.

There is no as such way of search engines to pick your title and description.
If you want the exact titles and description to be picked up by the Google then just add 1.75% around keywords in your content and the same keywords in your title and description.
