Does the sentence contain faulty parallel structure? the ice was a greater hardship for the electrical power company than the natural gas company.

What you're looking for is YES, yes it does have a faulty parallel structure.

I took the test and came back because I used the other answer and got it wrong. Didn't want that to happen to someone else. :3

                        Hope this helped you!!! :P

                                   Have a day

in june, we will have been married for eighteen months. (i am assuming this is what you want? the sentence, as you have presented it, is grammatically incorrect--   you want it corrected, yes? )
