There are four examples given of fractions in the end of the lesson : 

 tres cuartos, 

dos decimos,

 tres octavos, 

 un septimo  

These examples are supposed to show the need for plurals when the numerator (top number) is more than one.  Unfortunately all the numbers choosen ( dos and tres) end in "s".  I found myself somewhat confused, and wondering if this meant that the top number should also  have an "s", por ejemplo sietes ochos instead of siete ochos.   

 It would be clearer if you used included a fraction that did not end in "s";  por ejemplo  cuarto octavos instead of tres octavos. 

los humanos PARA sobrevivir en el planeta rojo. why use para here ? what is its significance? 

The English asked for "any animals" on that last sentence. So would the better translation be ¿ tienes algunos animales en casa?

Hola todos

So I can have a better understanding of this subtle distinction between these 3 conjunctions (pero/sino/sino que), can you please confirm if I'm correct in these following 3 examples which all share the same 1st clause: 

SINO >>> El médico no me recetó un jarabe __sino__ unas pastillas. (Because simple SUBSTITUTION ) 

PERO >>> El médico no me recetó un jarabe __pero__ con la condición que lo vea la próxima semana para una revisión. (Because MAKING A LIMITATION to the 1st clause) 

SINO QUE >>> El médico no me recetó un jarabe __sino que __ me dijo que necesité una operación . (Because DIFFERENT CONJUGATED VERB IN 2ND CLAUSE) 

Hopefully this can clarify these nuances in my head once and for all! 

Saldudos y gracias,   ~Oscar :) 

The RAE seems to say that it is correct to have no accent on the vosotros vorms of liar and criar.
