I'm reading the book Grammar in use and I faced a question that puzzled me. On unit 70 (countable and uncountable 2) it ask the following:
Which is correct?
- Our travel/journey from Paris to Moscow by train was very tiring.
At the back of the book it is written that the correct answer is journey but why cannot the word "travel" be used here? I checked the sentence "our travel from Paris to Moscow by train was very tiring." with the Grammarly app and it did not detect any mistakes.
