Singaporeans prefer NUS to Harvard?

Just saw the news that NUS has scored a platinum award in University catergory (first time this has been measured) in the Reader's Digest Trusted Brand Awards 2007.

Many congratulations for this accolade for NUS, however, there are a few queries that remain unsolved in my mind:

1. Did Readers Digest only base the Survey on "7,000 responses to questionnaires and telephone interviews from across Asia." Is this a representative sample and is the spread of respondents distributed equally across the countries?
   
2. Where does the Straits Times deduce that Singaporeans prefer NUS to Harvard as put boldly in their headline?

The Reader Digest website seems a little unfinished to me, wonder if they will update more information (especially about the other countries) soon.
