¿Cuántas personas hay en la casa? No hay _______   ni   nada   nadie

anonymous · Answer

Take a look at these two translations, side by side. 
You'll see exactly how match up: 

¿Cuántas personas hay en la casa?
How many people are in the house?

"Cuántas" means "how many"

"Personas" means "people."

"Hay" means "there are"

"Casa" is "house." 

Put it all together, and you get...
"How many people are in the house? 

~~~~~~~~~

"Ni" means "nor"

"Nada" means "nothing." 

"Nadie" means "nobody." 

~~~~~~~~~~~

I bet you can use that to help you fill in the blank.
