Hi. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.
"Engetter" is a word of French origin, which refers to the rejection and expulsion of something or someone. It is likely that in the text to which your question refers, this word has been placed with this meaning, to be sure of this, you should rewrite the sentence by changing the word "engetter" to its meanings and making sure the sentence is coherent. You can also see this by looking at the context of the sentence as a whole and identifying whether that context has something that is being kicked out or rejected.
Because her dad gave tips to Bruno in the game she was playing with Bruno. Her mother reminds her it’s only a game.
The phrase in this sentence is Nonrestrictive because there can only be one youngest brother, therefor the name Julian does not need to be in the sentence, because it is unnecessary to name him.
Hope this helps! :)
If you're asking for main idea, the main idea or thesis statement sentence is sentence 1, where they explain what the passage is about.
