That's an odd question as written. Was there any information about where they traveled to? Also, I'm not familiar with the geography of Rio. I know it has beaches, but are there also some high areas (I remember some pictures, but not sure if it was Rio)? Did 3 of the choices really go 75cm, 76cm, 77cm, that close together? The textbooks give 760mmHg as standard pressure at sea-level (but of course it varies), is that what they were getting at? If so, that isn't a very good science question, more of rote learning. Can you give some more details about this test? -- Erik Reuter http://www.erikreuter.net/ _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
