Are these sentences natural? Feb 10

[musicgold]

Hi,

Are the following sentences natural to a native ear?
1. Why don’t we have any example of frugality in this sequence?

2. Why are there no examples of frugality in this sequence?

3. I have always had a trouble with this file system.

Thanks,
MG.
