The question seems a bit incomplete but I believe the correct answer should be 2. was not.
That would correctly complete the sentence like so:
I was not there when the crime happened, I only heard about it afterwards.
Ich war eine lange Zeit krank
i'm not too sure though, but i hope it helps
Hi Klingelbaugh
All of the options are Germany so answers A, C, and D, are all the words ''no'' in Germany but B) is the word ''not'' in Germany so the answer would be Die Kinder essen nicht Gemuse. The answer is B) because its a negation word so opposite of positive and its the only different answer as well and in English the question is asking The children eat blank vegetables so the blank part is B) nicht which means not so The children eat not vegetables, I know that sounds odd but its a negation word.
