Although the rise in the Producer Price Index was greater than expecte

Hello rnn!

Thank you for your questions. I imagine other people are wondering about these as well! Let's go through them one at a time:

1. The verb should be the past tense "remained" to stay consistent with the non-underlined part of the sentence where it says "was greater than expected" and "most analysts agreed," both of which are also in past tense.

2. No, this is not parallel. When looking at parallelism with phrases or clauses, you need to include the entire clause - not just the parts that sound good:

B. that it was unlikely for the index continuing to go up and for inflation to remain

If the phrase "it was unlikely" wasn't part of this option, then it would be parallel. However, since we're talking about parallel phrases here, we must include both phrases in their entirety. The only other way this could have been parallel would be to say "it was unlikely for the index to continue going up and it was unlikely for inflation to remain."

I hope this clears things up!
