If there is a sentence-
English is not too difficult to master, ____ it gets easier and easier with practice
which of these words would be the best fit for the blank and why?
At the outset, it would appear that "as" seems a good fit here, but when you do think about it, even the other words look like a plausible option. In effect, it closely resembles a "cause and effect" scenario, hence the confusion. Other than "consequently", I think all the other words do fit here, at least in a way.
I did come across a similar question here, but this didn't help in getting me a certain answer for my question.
Please help, thank you.
