The expression "lie behind" means to be the reason or cause for something. It is usually used to explain the hidden or underlying factors that are responsible for a particular situation or outcome. For example, if a company suddenly experiences a significant drop in sales, one might ask what lies behind this decline. In this case, the phrase is used to explore the possible reasons or factors that led to the drop in sales. "Lie behind" can also be used to refer to something that is hidden or obscured from view but is still important. For example, the true motivation behind a person's actions might lie behind their words or outward behavior.
