What does this sentence mean, "Elle a posé toutes ses lettres au tour d'après"?

I learnt about the inverted question form and the inverted verb forms of quoi and how they work. Quoi becomes que or qu'. Additionally, I learnt about est-ce que and it uses the question word first and then the inverted verb and then the subject. 

In the exercise entitled "A Book Lover," there is a phrase "...rien qu'en observant ses grands frères et sœurs." When I gave exactly that spelling, the s's at the end of "frère-" and "sœur-" were marked as incorrect...even though they were present in the correct example, and the narrator gave us a very clear clue that the words were plural by the way she pronounced "ses."  Just letting you know about this glitch in the program. 

Also, I frequently find myself needing a 2nd or 3rd listen to be certain about certain words. Sometimes I'm able to get the program to repeat the recording, often not; when I do, I often need to click on the audio button multiple times before it complies. Either I'm trying to cheat, or the function allowing us to hear the phrase over again doesn't work very well. Please let me know which is the case!

Otherwise, I'm enjoying these challenges very much!

I noticed that in your audio of "j'étais allé", there is not a liaison. Is it optional?

Is it usual in French to use “parfum” to describe the taste of food?  Or is the speaker describing the smell of the food?  If the speaker is speaking of the good smell of food, is this a usual expression concerning food as well?

I am not an astronomer but I believe the correct term for describing earth's movement around the sun is not "rotation" but "revolution."  I think it would be correct to say,

"...en fait, la révolution de la Terre autour du Soleil dure quelques heures de plus chaque année."
