Such volcanoes are devastating, but very rare. The last one happened at Toba in Sumatra, Indonesia, 74,000 years ago. The active volcanic system at Yellowstone National Park has resulted in super-eruptions-the most recent happened 640,000 years ago. Yellowstone's volcanism is powered by magma rising from a hotspot.
A biased opinion is based on a preconceived notion or idea about a thing, person or group of people based on personal beliefs. In psychology, a bias is known as a cognitive shortcut..

This is an opinion, but you have to know that eloquent is a descriptive word to for this to become clear. Descriptive words are subjective, or state someone's opinion.

A bias is an opinion or an attitude we have for or against something. A bias usually stems from our feelings rather than from rational thought. What is very important to realize is that ALL of us are biased. We are biased for or against certain people, activities, and ideas.
