It's a great place to live apart from the increasing volume of ________ that passes under my window every day.  transport  traffic  vehicles  circulation

To choose the most suitable word to complete the sentence, we need to consider the context. The sentence indicates a negative aspect of living in a particular area, specifically related to something that passes under the window every day.

The options provided are:

1. transport
2. traffic
3. vehicles
4. circulation

Analysis of Options

1. Transport - This is a general term that refers to the action of carrying goods or people. It doesn’t fit well as it’s not usually used to refer to the volume of something passing by.

2. Traffic - This term specifically refers to vehicles moving on roads. It is commonly used to describe congestion or the flow of vehicles, making it a strong candidate.

3. Vehicles - This word refers specifically to the machines used for transport, such as cars or trucks. While this could technically fit, it does not capture the idea of volume as effectively as "traffic."

4. Circulation - While this could refer to the movement of vehicles, it's more commonly associated with the movement of fluids or the distribution of resources, making it less appropriate in this context.

Conclusion

The word "traffic" is the most fitting option as it directly relates to the increasing volume of vehicles and effectively conveys the context of congestion under the window.

Final Answer

traffic
