D) Music? Really? I'd take a rock concert over the constant drone of traffic any day. B) Transport is the clear winner.

I agree, B) Transport is the obvious choice here. The sound of honking horns and screeching tires is enough to drive anyone crazy!

B) Transport is the correct answer. Noise from vehicles, especially in urban areas, is a major source of noise pollution.

Music could be a factor, but I doubt it's the greatest source overall. Transport seems more likely based on what I studied.

I recall reading that military activity is significant, but it seems more localized compared to transport.

I'm not so sure. I feel like large crowds can create a lot of noise too, but I guess it depends on the context.

I think transport might be the biggest source, especially with all the cars and planes. I remember a practice question about urban noise levels.

I'm a little confused on this question. I can see arguments for a few of the options. I'll have to carefully weigh the pros and cons of each before making a decision.

Transport has to be the answer here. The noise from cars, trucks, planes, and other vehicles is just so pervasive in developed areas. I feel confident about this one.
