tim Wrote:this whole discussion is irrelevant. "is" or any of its other forms is not a parallel marker. so to ask yourself whether things on both sides of "is" are parallel means you are wasting time dealing with a grammar rule that is not applicable. one of the most helpful things you can do for yourself is to recognize the signals that indicate you are dealing with a particular grammar rule so you can analyze the sentences efficiently..
Tim , I think I need to point you to the relevant section in the Strategy guide so you know what I am refferring to.
Here's text from the Strategy Guide - Copied
Strategy guide 4 Pg. 57
"A more subtle form of parallelism involves Linking Verbs."
"When you use a linking
you have to make the subject and the object parallel"
"The most common linking verb is naturally the verb to be"
And as far as I know "is" is a form of "to be"
Not sure why you think the discussion is irrelevant.
