When does one use 'nicht' in these sentences?
*) In Duolingo, there is a sentence lautet "Viele Juden essen kein Schwein,". But someone replied "Auch viele Muslime," and then a native German speaker added 'nicht' at the end of the sentence. So it becomes "Auch viele Muslime nicht,".
Why do you need 'nicht' in that sentence?
*) Why is it "Keine Umfrage zu der Wahl," instead of "Keine Umfrage für die Wahl,"?
*) What is the difference between der Zusammenhang and der Anschluss?
In both German and English you can't write this sentence:
"Many Jews do not eat pork, and many Muslims too."; "Viele Juden essen kein Schwein, und viele Muslime auch."
You have to write it specifying the negation (even if the sentence is a subordinate), and also putting "auch" at the top of the phrase:
"Many Jews do not eat pork, and many Muslims do not too."; "Viele Juden essen kein Schwein, und auch viele Muslime nicht."
You could also write:
"Also many Muslims do not (eat pork)"
"Auch viele Muslime kein Schwein essen" or "Auch viele Muslime essen es nicht".
I think that "die Wahl" is written as "der Wahl" because the sentence requires a dative (and that explains also the presence of "zu"). In English it would sound like: "No polls to the election", using "to" instead of "for".
[incorrect, see below]
A "Zusammenhang" is a "connection", and an "Anschluss" is a "context".
"Beratung von Bürgern im Zusammenhang mit Anschluss des Grundstücks an den öffentlichen Kanal."
"Consultation of citizens in connection with the context of property of the pubblic canal".
I believe you have your definitions reversed. Anschluss you will find in assembly instructions, when fitting your kitchen cupboards together, plugging in your tv, usb or computer ports. It is a physical connection, joining components together. Zussammenhang is studied in the Abstracts module and concerns the coherence, correlation, context of z.B. a sentence.
I'm intrigued about that quotation, I think it may refer to connecting a new property to the public utilities. I can't wait for a native speaker to answer the OP. Public has only 1 b.
