... snow enclosure near the camp being almost wholly destroyed.

[longnguyen1994]

"None of the dogs survived, their hurriedly built snow enclosure near the camp being almost wholly destroyed. The wind may have done that, though the greater breakage on the side next the camp, which was not the windward one, suggests an outward leap or break of the frantic beasts themselves."
I'm a bit confused by the part in bold. The way it's "being" and not "was" here make me unsure of how the 2nd half of the sentence relate to the 1st half. Is it:

A) None of the dogs survived because their snow enclosure was almost wholly destroyed.

or

B) None of the dogs survived, and also, their snow enclosure was almost wholly destroyed.

or is the relationship between these two halves here something else?

I know that you're a new member, but in future, please do not post the same question simultaneously to more than one forum. Doing so wastes our valuable time. Instead, post your question to one forum and wait for replies. If you're not satisfied with those replies, you can try another forum, but please indicate in your thread that you've already asked the same question elsewhere (provide a link), and outline why you were not satisfied with the answers you received already.

I'm a bit confused by the part in bold. The way it's "being" and not "was" here make me unsure of how the 2nd second half of the sentence relates to the 1st first half. Is it: Which of the following is equivalent to the original?

A) None of the dogs survived because their snow enclosure was almost wholly destroyed.
or
B) None of the dogs survived, and also, their snow enclosure was almost wholly destroyed.

or If it's neither, is the relationship between these two halves here something else?
