Usage and Grammar

Q. My younger colleagues see absolutely no problem with this construction: “Based on the report, the authors drew up a summary.” I see this everywhere now and wonder if my reaction, which is to change this into “On the basis of the report, the authors . . .” or “The authors drew up a summary based on the report,” is because I’m a dinosaur.

A. Most likely; but if it’s any comfort, we are dinosaurs, too.
