Is this homework?
Interested in Language
This is an exercise,in which we have to correct the mistakes.
Trains in London are more crowded than in Paris.
I think the mistake is the missing definite article "the" before "trains".
What can you say?
The author of the book.
***** NOT A TEACHER *****
The beloved expert Michael Swan says:
"We do not use the with ... plural nouns to talk about things in general."
He gives these examples:
a. Books are expensive. ("All books")
b. Life is complicated, ("The whole of life.")
c. Nothing can travel faster than light.
BUT sometimes "it is difficult to know whether or not to use the."
Mr. Swan gives this example: " I wish the trains were cleaner and more punctual."
He explains that "the" is proper because "the listener / reader knows which ... things we are talking about."
Only my examples:
"Teachers have a hard time." (Teachers in general.)
"I think the teachers should give us less homework." (You are perhaps talking with another student at the same school.)

What about this theory?
When saying "trains in London are more croweded than those in Paris" we are referring to the London trains for which we have to use the definite article "the"
When referring about trains in general, then the best variant would be :"Trains are faster than cars" without the use of the definite article "the"
Is this concept correct?
