The text says:

Desde entonces, hemos sido como uña y carne

In all the lessons with desde to mean 'since' we are told to use the present tense.

I put 'Desde entonces somos como uña y carne' but was marked wrong. What is the error here?

Gracias

there is another chapter where "Having done something" with the action as subject or direct object of a sentence using El Infinitivo Compuesto (= haber + participle)

How does it differ from using infinitive?

Fumar es malo para la salud

Haber fumado es malo para la salud

if I were to guess, I am guessing that using el infinitive compuesto is that, the action was indeed being carried out where as using infinitive is just a general statement. the person we are warning regarding smoking is bad, did not smoke.

Whereas if the person indeed smoke, we will say haber fumado es malo para la salud

¡Hola! Tengo una preguntita...

Why do we use "es sabroso" here when in other exercises we've opted for "está rico/delicioso etc", which seems to be a similar idea?

¡Muchas gracias!

Hi Inma

Am I right to assume that these essentially translate into English as the same thing? Otherwise, could you explain any other differences in meaning that might exist? 

1) Su avión ha debido retrasarse

2) Su avión debe haberse retrasado

AND that adding 'de' also makes no difference to the meaning (other than maybe 'strengthening' the assumption as we learned about here: Spanish modal verb Deber versus Deber de (obligation and assumption))? 

Saludos
