Which word means to disturb greatly?

• A. Interfere
• B. Perturb
• C. Deceive
• D. Modify

Answer: (B)

The word "perturb" means to disturb greatly or to throw into confusion or disorder. It conveys a sense of agitation or anxiety resulting from some sort of interference or disruption in a person's normal state. This makes it particularly fitting for describing a situation where someone is deeply unsettled or bothered by something unexpected or distressing.

In contrast, "interfere" generally implies getting in the way of something but does not inherently capture the intensity of disturbance implied by "perturb." "Deceive" refers to misleading or tricking someone, which does not relate to disturbance. "Modify" means to change or alter something, lacking any connotation of disturbance or emotional turmoil. Therefore, "perturb" is the best choice, as it directly addresses the idea of significant disturbance.
