It's a sentence about 'sea' and 'river' in general. Is it correct to say:
1.The sea and the river are dangerous.
Can I also say:
2. A sea and a river are dangerous.
Is it the same as with:
A tiger is a wild animal.
The tiger is a wild animal.
It would only be usable if it were true that all seas and rivers are dangerous. I don't think that's the case.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
