Having a question about context and details!

While reading third paragraph of this last paragraph, the part "glorification"~ made me make a narrative that nationalists may have exaggerated achievements and there could be questions regarding this point.

Looking into Q22 (C)

Most historians- should be specifically "US" historians

Make the histories of the nations about which they wrote seem more glorious than they actually were

I thought it's correct as glorification could be interpreted as exaggeration. Thus, making it more glorious than they actually were.

Does "glorify" exclude the meaning of exaggeration?

As a non-native speaker, some words are confusing...

Any tips for improving context interpretation is also welcomed:)
