Hola,
I don't understand how 'debido a que' is a wrong answer in the test for this question?
Ella dejó a su marido ________ su mal humor y sus celos.She left her husband because of his bad temper and jealousy.
I guess it's because it's a combination of nouns (humor, celos) without any further embellishment, but it's confused me because of the explanation referring to a noun, rather than nouns plural:
"If we use debido a que, it can never be followed just by a noun, it needs a phrase."
Gracias,
