¿entiendes las palabras de tu profesora? the "personal a" is necessary. the "personal a" is not necessary.

The correct answer is: [B]:

"The 'personal a' is NOT necessary; since the "blank space" given for this very question does NOT precede a person's name (or even a pet animal).

hey, i'm sorry to disappoint you, but we can not answer your question today. we do not have your audio clip, therefore we can not listen to the audio about the schools in nicaragua. if you are able to put what the audio recording says here, i'd gladly be able to you.

have a nice day and happy halloween!
