The answer is C because tengo means I have to which translates to necesario
I don’t know if this is a question but I completely agree...btw if this is a question somehow just comment and I’ll answer
If you wanted this translated here u go: “In Costa Rica, they teach technology classes in English to prepare the students to work for South American companies with offices in Costa Rica.”
The answer would be D. como means like what kinda. so it would be: Como te llamas?
“Que”is the word that goes in the blank
Hope this helps
