Questions & Answers about Z powodu tej atrakcji mnóstwo ludzi jeździ tu pociągiem.
Why is the verb jeździ in the singular when the sentence is about a lot of people?
Could I use jedzie instead of jeździ here?
It would change the meaning. Jeździć (which gives us jeździ) is a verb of motion used for habitual or repeated travel. Using jedzie would mean a specific multitude of people is currently on their way here right now as a single group.
Why do we use tej atrakcji instead of the basic form ta atrakcja?
The phrase z powodu (because of / due to) always forces the noun phrase that follows it into the Genitive case.
How would I apply this lesson's evidential mieć to say 'A lot of people supposedly travel here by train'?
You would use the third-person singular of mieć to match mnóstwo, followed by the infinitive of the main verb: Z powodu tej atrakcji mnóstwo ludzi ma jeździć tu pociągiem.
