Answer:
where is the question?????
Answer:
It is grammatically incorrect.
A: Willst du Russisch lernen?
B: Nein, aber ich würde/will gerne Spanisch lernen.
Answer:
I think it's all of the above. But It could just be Bruder if you have to pick one.
Explanation:
Cognates are two words from different languages that have a common origin/meaning/spelling. All of these German words are very similar to their english definitions.
If none of the above isn't an option then choose Bruder, because I know they have a similar origin.
