Translation:There are a lot of cars.
Are there more detailed notes which highlight this 'Is Many' I can read and go over before the course tests me on it? I've run into this issue a few times. I make my own notes on words and sayings I haven't been taught via docs but it would be nice to go over it before running into it.
It may be a Duolingo thing I'm not used to. I personally find it hard to learn having new things thrown at me one after another like this eg each individual lesson highlighted the phrases you were about to go over I would retain more.
