That would be A Nacer When a baby arrives in the world, you use the verb to be born
The correct answer is A, La. Let's look at this!
"Mochila es negrea"
If you are referring to the backpack (Mochila) the pronoun is feminine. There's really no explanation further I can give you as to why it's feminine, just the way the Spanish language said it would be feminine,
Also, if you are referring to black (negra) this is feminine because you are referring to the backpack as feminine, therefore La, should be your prounon!
If you don't understand let me know! I hoped this helped! :)
The two differences are that they do not look alike and they do not have the same books?
I think it's that not sure xD
Hopefully this helps!
