… the last decade, technology has advanced rapidly.(A) Between(B) From(C) To(D) During

To determine the correct preposition to fill in the blank in the sentence, let's analyze each option provided.

1. Understanding the Sentence Context
   The sentence discusses the advancement of technology over a specific period, which is the last decade.

2. Evaluating Each Option:

   • (A) Between: This implies a range between two distinct points, not appropriate here since we are not specifying two endpoints but rather a duration.
   • (B) From: This would typically indicate a starting point but doesn't encapsulate the entire duration as required in this context.
   • (C) To: Similar to "from," it also indicates an endpoint and does not convey the sense of duration.
   • (D) During: This indicates that something happens within a specific time frame, which fits well with the context of technology advancing over the last decade.

Conclusion

The correct choice is (D) During.

Final Answer

During
