1.) tu 2.)yo 3.)Ella 4.)yo 5.)nosotras
For the first blank is “conoce” and for the other one is “sé”
when ir and er are conjugated the only continuation that would be similar is yo say if you have comer and vivir
comer vivir
yo=como yo=vivo
the differences would be the meanings because just like the yo meaning i ts means you your saying what your doing for example yo vivo= i live but its not always you its could be others too just like el/ella=vive it would mean he or she live so the difference would be the meanings
i dont know if this helps
It is A for sure! Hope this helped!
