"¿La universidad tiene tres bibliotecas?"
Translation:Does the university have three libraries?
Yes. In both English and Spanish, we can ask a question by making an indicative statement, rather than using an interrogative sentence.
Both languages do that through using rising intonation, and using a question mark in print.
That said, I do believe that DL should use the interrogative sentence form (reversed subject-object) more often, and use the indicative (statement) form less.
Just like in English you must conjugate the verb to the correct subject. 'I have' vs 'He has'. The same holds true for Spanish.
(tú) Tienes = you have
(él, ella) Tiene = he/she/it has
This site might help you with how to conjugate (or change) the verbs so that they correspond to the correct subject. A word of warning... it contains a lot of information. Don't be discouraged because most verbs in Spanish follow a pattern based on their endings (ar, er, ir).
