A great resource for learning german is the youtube channel Easy German. They go on to actual german streets and interview germans in german. This gives you a total immersion into the language. And it has English subtitles below the german subtitles so you can listen and see the words in real-time life conversations. I highly recommend it. Also check out Deutsch Extra, its a tv show that's used to teach german. All on youtube
Please try not to let that frustrate you.
In order to save us course contributors from typing hundreds (or sometimes thousands) of very similar sentences, we can create multiple sentences at once by using alternations, e.g. [Du bist/Ihr seid/Sie sind] sehr [seltsam/komisch/merkwürdig] would turn into 3*3=9 sentences.
It’s often difficult to form such multiple alternatives in a way that will not match the default/best translation, and so very often, “the same sentence” will be in the list of alternatives twice: once as a product of such an alternation and once typed directly, typically as the best translation.
You may then see “another correct answer” saying the exact same thing.
Please just treat it as “Correct!”.
The sentences in DL aren't meant to be memorized as they are. They are often just almost random sentences built with the vocabulary the learner already knows and help to form a better understanding of the grammar and structure of the language.
If you just want to learn useful phrases, there are other better resources online for that.
And to the question: I can think of many contexts where I could say this sentence to my children, in a playful manner.
Help, please! In this lesson it is explained the accusative pronouns as follows: ich/mich; du/dich; er/ihn; sie/sie; es/es; wir/uns; ihr/euch; sie/sie. So, why it is "Kinder, mögen wir das?" If I follow the rule, I would write "Kinder, mögen wir es?" What did I misunderstood?
