I prefer living in England to living in Greece.
I prefer living in England to Greece.
Which sentence is correct?
I agree...the first is technically correct. Just to add though, the second is often heard in speech and is understood to mean the first. With brief comparisons like these, the parallelism is understood and therefore often neglected (speech efficiency!). The rule is important though, especially in writing and especially with longer phrases!
Comparing living in Greece to living in England is sensible, and comparing England in general to Greece in general is sensible, but comparing living in England to Greece in general is not.
The same applies to the other, identical, question you asked in another thread...
Thanks, Andrew. I appreciate your lucid reply very much.
