@Danaizha Embedded conditional has a necessary condition that is also acting as a sufficient condition, such A -> B -> C. As you can see B is a necessary condition for A and it is also a sufficient condition for C. So, because A, B, C are in a dependent relationship with each other, that means they are embedded or entertained with one another. Separately, conjunction are words such as 'and,' 'with,' and 'but'. These words create a bridge between two or more ideas. Hope this helps.
