Understanding the Sentence Context

The sentence "The reminder has gone out on __________ occasions, requiring personnel to complete their personal files" needs a word that indicates the frequency or number of times a reminder was issued. The context suggests that the reminders were sent more than once, but not necessarily an exact or very large number.

Analyzing the Options

Let's examine each option to see how well it fits the blank:

• further: This word usually implies additional time or extent. For example, "We need to discuss this further." It doesn't fit well with "occasions" in this context.
• several: This word means more than two but not many. It fits perfectly here, indicating that reminders were sent out on multiple, distinct occasions.
• untold: This means too many to be counted or described. While possible, it sounds a bit too dramatic for a standard reminder about personal files unless the situation is very unusual.
• most: This means the majority or a large proportion. It implies a specific, high frequency that might not be accurate or intended.

Choosing the Best Fit for Occasions

The word several is the most suitable choice because it accurately conveys that the reminder action happened multiple times without being overly specific or exaggerated. It's a common and natural way to describe repeated events in a professional context.

Comparing Options in a Table

Therefore, the completed sentence reads: "The reminder has gone out on several occasions, requiring personnel to complete their personal files."
