What is the exact translation of this sentence?


There is this sentence in my textbook that I don't quite understand the
structure of: スイスのクレーマーさんですか、ドイツのクレーマーさんですか． So if I understood it correctly
it's asking if that person is from Switzerland or from Germany but can you
just connect those 2 things with a comma? The whole sentence sounds weird to
me. Also, is there another and maybe better way of saying this question?




The question literally translates as:

[code]

    Is it (the) swiss Mr. Kremer or is it the german Mr. Kremer?
    
[/code]

(It could could be also Mrs. instead of Mr. depending on context.) You might
be confused by the literal translation since it implies that there are 2 Mr.
Kremers, one from Germany and one from Switzerland.

But despite this somewhat strange phrasing (which might be, however, clear
from context) the

[code]

    ...ですか、...ですか。
    
[/code]

is a perfectly valid way to ask a 2-way question: see e.g.:
