Translation:He is Bruno.
The reason for this construct is to teach that "c'est" also means he is, she is, this is and that is, and that is how the French understand it when referring to people. Reflexively, new learners see "c'est" and think it is or it's, but that isn't always the case. The next thing to learn is when to use "c'est" versus "il est/elle est." The lessons in the skill "Gallicism" are an attempt to clarify that.
There are set rules when to use each and they are not interchangeable. https://www.thoughtco.com/french-expressions-cest-vs-il-est-4083779
Well, if someone asked "Who is he?", then you could answer "He is Bruno." but in French you have to use "C'est Bruno." and they are trying to get you to understand that "He is Bruno." cannot be "Il est Bruno." in French, as you must say "C'est Bruno."
I agree though that if someone said "Who is that?" we would answer "That's Bruno." and I don't know another way to translate that. If you knock on the door, and someone asks "Who is it? you would answer "C'est moi." So, again, "C'est" can be "It is", "That is", "This is", "He is" or "She is". I think that they are working on the last two meanings in this lesson though.
A man just walks thru the door on the other side of the room and someone asks, "Who is that?" "It's Bruno." This is what Americans say, not "He is Bruno." To get "He is Bruno" you have to start with a question of which person, or maybe dog, is Bruno among two or more. "Is he B?" "No, he is B," you would say, pointing at B.
Somehow today, after getting all golden to 62, lots of my circles have gone back to colors, lots of them, from the very first one, so that is why I am here on this lesson. So I know that this lesson is trying to get across that people say "C'est" instead of "Il" when they mean "he." But this lesson does not get that across.
Who is that? That's Bruno. Yes, we do say "it's" too in English. At the moment we haven't decided as a team whether to accept "it" in this particular lesson, and of course the main goal is to demonstrate how it is used in French and to show early on that "c'est" can mean much more that "it's."
As far as the colored skills, whenever a new skill is added to a tree or new words are added to a skill that weren't there before, the circle becomes colored. Since this a new tree, there were many changes made. Unfortunately only staff can answer your questions about why the release was done this way or why there isn't a way to test out of an early skill. (I wish!) Fortunately, you shouldn't have to repeat all the lessons in a skill, it goes very fast, and the word strength for words you have already done has not changed.
However if you would like to file a bug report, here is the form. Or you can create a new post in the discussions. Those are two ways to get the attention of the staff and perhaps in future trees they will open up past checkpoints during A/B tests for more advanced learners to test out.
I understand the intent of the lesson, but it is also important to understand the equivalent English translation. "He is Bruno." makes perfect sense in English, and there are plenty of situations where it may be important to emphasize Bruno's gender, but it does feel a bit peculiar.
Most often, we couldn't care less whether 'Bruno' is male, female, fish or fowl! When Bruno shows up, or is in our presence we greet the occasion with, "It's Bruno!" or identify Bruno to others with, "It's/this is/that's Bruno." and the rest is for the others to figure out. (Usually not a very difficlt task.)
In response to "Which one is Bruno?" the most likely answers would be, 'That one' or 'Him' However, the point is that while 'He is Bruno' is possible in very rare circumstances, 'It's Bruno' should be accepted by DL, as it is the most likely sentence to be said in the UK. I couldn't speak for other English speaking countries.
It would be very rare, if ever, that "He is Bruno" would be said. As has been said, "It's Bruno." would be much more likely. It would be, " His name is Bruno." if talking about his name. So, if It's Bruno is wrong, as we have been marked, how do you say, "It's Bruno." in response to "Who is it?"? Also, in response to "Who is he?", it's highly unlikely that "He is Bruno." would be an acceptable or sensible answer. It would have to be qualified by, e.g. Amy's boyfriend, Peter's dad etc.
The French have very specific rules when to use “c’est” and when to use « il est » . With a name following, it will be « c’est » .
The following link explains when to use each, but please press “Continue reading” as the first page has barely anything. https://www.thoughtco.com/french-expressions-cest-vs-il-est-4083779
It does not exist in French. Proper names by themselves come after « C’est » to mean “He is Bruno.”, “It’s Bruno.”, That’s Bruno.” or “This is Bruno.”
« Il est » and « C’est » are not exchangeable as there are set rules for when to use each of them. https://www.thoughtco.com/french-expressions-cest-vs-il-est-4083779
Of course, you can say « Il s’appelle Bruno. » if you are just introducing his name.
It is rather amusing that French is so specific about which you use. « C’est Bruno. Il est médecin. Il est intelligent, mon ami Bruno. C’est bizarre. C’est mon ami, mais je ne sais pas s’il aime des frites. »
