Spanish language Q&A Forum

In a quiz question (20% is a small number),       why is the answer el "20 %" not accepted? The lesson seems to suggest that either that or El '20 por ciento" should be ok. Thanks.

I wonder what the purpose of the subtle but significant change of meaning in Tanta luz no es buena to mean "This much light is not good." instead of "So much light is not good?"

If one is hired as a translator, I don't think one would take it upon oneself to make a change of the speaker's meaning in such a way.

I really enjoy reading Spanish history. Do you have anything on the Inquisition?

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
