Question

3- Do you know the difference between there is and there are? please explain​

Answer 1

La diferencia es que “there is” se habla en singular, o sea un solo sujeto u objeto, en cambio, “there are” se habla en plural, o sea donde pueden haber más de un sujeto u objeto.

The difference is that "there is" is spoken in the singular, that is, a single subject or object, instead, "there are" is spoken in the plural, that is, where there may be more than one subject or object.
