Hi,everyone.I read an article with the title 'Competition between US and China sparks off benefits for both countries'. But I am not sure whether native English speakers use the phrase 'spark off benefits' in daily life or literacy and whether it is correct and nature to say 'something sparks off benefits' in an essay? Thanks a lot!
In this case, the competition or conflict between China and America is likened to two rocks colliding. This produces sparks. But the sparks can have benefits, for example by producing fire. If all those elements (or similar ones) aren't present, the metaphor doesn't work.
