this is the right answer
I couldn't believe this poll. It is obviously "at" and only "at". But the poll results showed a pretty even spread.
So either most users are not native speakers or there is some variation between countries.
I knew how to sort this out, however, I did a google search.
(remember to out the sentence in speech marks).
The result was clear:
if we take into account a few errors by non-native speakers, then "at" is without a doubt coorect and "in" is certainly incorrect.
And it also indicated that most respondents were monkeys.
Agreed, Mark. How the heck can you reside within a disadvantage.
Yoiu are never "IN" an advantage, but AT an advantage:)
