Exercício: Although x Still x Yet x Despite

Earth is the only place we know of in the universe that can support human life. ______ human activities are making the planet less fit to live on.

Opções:
  1. Although
  2. Still
  3. Yet
  4. Despite

Qual das opções é certa? Eu escolhi a opção 'although' porque eu acho que 'yet' é algo que ainda não aconteceu.

E aproveitando alguém sabe me dizer sobre: Although / Still / Yet / Despite ?

Obrigado.

To me you are right, and the alternative would be the letter a. (although)

Despite would be used with the following structures:
despite + noun
despite + verb + -ing

So, it´s out of question.
=========================================
Yet
Couldn´t be used in one of the following meanings (from 1 to 7).

And not as a conjunction as well. (see the notes)

=============
Still
It doesn´t fit in the above clause as well.

============

So, what is left is although, wich is used with the structures:

although + a clause

Yesss!
