hoose the option that best completes the sentence. The ______ of armed robbery has been on the increase.

To complete the sentence accurately, we need to choose the word that correctly aligns with the context of an increase in occurrences over time. Here are the meanings of the options provided:

• Incident: This refers to a single event or occurrence. Although it relates to an event, it does not emphasize frequency or rate. Therefore, it doesn't fit the sentence that implies an increasing trend.
• Accident: This refers to an unexpected event, often causing harm or injury. It is not specific to trends or rates, so it doesn't fit well with the sentence’s meaning that indicates continuous increase.
• Incidence: This refers to the frequency or rate of occurrence of something, especially when describing how common particular events or cases are over a certain period. Since the sentence is about the **increase** in occurrences of armed robbery, this option fits perfectly as it relates to the number of times an event happens.
• Accidence: This refers to the part of grammar that deals with inflections. It is not related in any way to describing an increase in events.

Therefore, "The incidence of armed robbery has been on the increase." is the most suitable completion for the sentence because it specifically denotes the rate or **occurrence of a phenomenon, highlighting that it is rising.**
