Am i correct on above

I also want to know "reporting " is refering to which thing.
I read somewhere I dont remember where but i am sure i read
reporting is refering to "Data" and it not correct.

Please explain how to be 100% sure to which thing __ing is refering.Generally when Ing modifier comes after a comma foolowing a clause.Ing refers to subject of that clause

Clause +,+ ing subject

ing , noun + clause --- ing refers to noun following it

But i am not sure about

Clause , ing modifier , phrase
i am not sure about this format (mentioned in question under discussion)

Please explain

If no screenshot is posted, the discussion will have to come to a halt.

The answer to your question, though, is that the part of the sentence from the beginning up to "1980" is by itself a complete sentence. So, the analysis of "comma + __ing" is the same as it would be if you stopped reading at "1980".
I.e., in the original, that modifier is mistakenly describing the data.

thanks a lot for reply
sorry sir i dont have screen shot of this question

I have tweaked the sentence.
Please answer if it is fine as per norms of forum

In the following sentence
Data gathered by T.V reporter has been analyzed by news editor, reporting that the world's economy has become about ten percent more profitable since 1980,due to more vigorous business growth associated with alcohol industry

why reporting is not refering to editor.
I read "data...editor" together than take a pause because of comma and then read from "reporting".this way it seems to me that reporting is refering to editor.

If we have only following part of sentence under discussion.I feel "reporting refers to data (subject of previous clause)".Which is also wrong because data can not report itself.

I feel if we go with context reporting can refer either Data or editor

Data gathered by T.V reporter has been analyzed by news editor, reporting that the world's economy has become about ten percent more profitable since 1980

That's not how "comma + __ing" works. So, no.

And that's the last we can discuss of this problem without proof that it's authentic. If you find such proof, please post a new thread.
Thanks.
