Превод - Датски-Английски - Det Palæstinensiske flygtninge problem opstod af...

Maybe homework, but I discovered it to late ...

Hi Pia, yes you're right it may be homework, however since it's done, let's just correct a few things.

"The sad results...are visible .... (in connection with the Palestinian exile)"

This part in brackets does not sound well, perhaps it should be only: "in the Palestinian exile"

"With this policy one (?) tried to create a homeland in Palestine exclusively for Jews."

Who is that "one"? The government?

Yes, "in the Palestinian exile" sounds good to me and it doesn't affect the meaning I think. But ....can't you write:"and in relation to the Palestinian exile"?

It doesn't say in the source who the "one" is, but you are right (again) ... it must be the government or some authority in the country.

So, let's make this clear.
1- you ask if you can write: "and in relation to the Palestinian exile". Well, that's a possible sentence, however in this case you have to match this part with the rest of the sentence giving after the preposition the same kind of grammatical category (in this case a noun):
"The sad results of this strategy are visible in the Palestinian refugee-camps and in the Palestinian exile."

About that "one" if it's not clear that it is "the government", perhaps it would be better turning the sentence into passive.

"With this policy, an attempt to create a homeland in Palestine exclusively for Jews has been (is being) made."

Thank you Lilian for your lesson
It's not that easy for me to keep up with the English, but I think that I understand what you mean.

I'll correct now!
