Which epoch covers the time from 5 million to 1.8 million years ago?

1.eocene
2.miocene
3.paleocene
4.pliocene

Let us define each of these epochs.

1. Eocene - covers 56 to 33.9 million years ago after the extinction of dinosaurs.

2. Miocene - covers 23.3 to 5.3 million years ago where countries had warmer global climates

3. Paleocene - covers 66 to 56 million years ago where the forests were very dense and there was ecological evolutions

4. Pliocene - covers 5.3 to 1.8 million years ago when grasslands were abundant

From the choices, the answer would be Pliocene. This is the shortest epoch of the Cenozoic era.

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : )
