Hola,
In the sentence "Therefore, time should be invested...", I answered "Por lo tanto, se debería invertir el tiempo" while the given answer is "Por lo tanto, se debe invertir el tiempo". Since the English sentence shows 'should', shouldn't 'se deberia' be more appropriate than 'se bede' which would translate to 'must' rather than 'should'?
Gracias,
Benhur
