It is perhaps clearer in other languages, but conjugated verbs in English<span> can also sometimes tell us something about how many people are participating in the action of the </span>verb<span>. For example, singular subjects (he, she, it) in the present simple tense have an “s” added to them when </span>conjugated<span>: He sings. She reads.</span>
Incorrect because it would be “nosotros no llevamos” but it says YO. in order to correct it you’d need to chance the YO to NOSOTROS or change the verb to llevo.
Everything seems to be correct. Great job!
