I wonder whether the following sentence is correct or not.
"Ten minutes suffice to train on the Segway, learning to maneuver it with ease." (from an ad.)
From my understanding, when two independent sentences are connected, a coordinator or subordinator must be used. If the above sentence is grammatically correct, please let me know why? and if incorrect, please let me know the correct sentence. Thank you very much!
It's a lousy 'sentence'. It expects us to guess what the subject of 'learning' is.
