There is no picture. But to translate that in spanish is: ¿Qué están haciendo las personas en la foto?
You could say this:
Que occurio fue que cogí la gripe. Estuve enfermo durante once días.
Translation to English:
What happended was that I caught the flu. I was sick for eleven days.
It means one "doesn't have too" or "you should not"
Depends on the context
The level of quality and complexity of flamenco is comparable to that of jazz and classical music.
