Here is one of the OG10 eg:

210. Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant
fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized
spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.
(A) extending
(B) extends
(C) extended
(D) it extended
(E) is extending

Answer to Question 210
Choice A, the best answer, preserves grammatical parallelism while allowing for logical expression of temporal
relationships; A employs the parallel participial phrases spawned... and extending ... to modify filigree. Other
choices present different grammatical constructions that are not participial modifiers and thus not parallel to
spawned: extends in B is a present-tense verb; it extended in D begins a new clause; and is extending in E
ungrammatically introduces a new predicate. In C, extended is nonparallel if it is assumed to be a past tense verb form; if it is assumed to be a past participle, it illogically states, as does D, that the filigree extended only in
the past.

hope that helps
Shoot, this example is opening up another can of worms for me.

Question from this example I have is, what is the difference between present progressive and present participle? After reading some more, I think I may have come up with an explanation.

Present progressive is a verb in -ing preceded by auxiliary BE, and it's a finite verb constituent that can function as a main verb in a clause. Present participle is a verb in -ING form without auxiliary BE, has no tense, and cannot function as a main verb. Therefore, present participle can only be a modifier of some sort, as in the case of answer A, and E is wrong because it introduces a new finite verb.

Now my question is then, do all the modifiers - relative and non-relative - have to be without a finite verb like an absolute phrase?

And it has been said in the context of this sentence, which does not need the verb 'differ' to be in the passive voice. If the past participle of the sentence were used in the sentence, it could only be used as verb of a passive voice. And hence, I have said so. If you like to generalize the wording, you can write-intransitive verbs cannot be used as past participle in the sentences in which it will be used as the verb of a passive voice. Ok?
I understand what your statement said, and yes, I am a student learning from the same materials, thus I am questioning what you said with what I have learned.

From my reading, I do not believe the statement you wrote is correct.

Intransitive verbs has to do with construction of active and passive voice, and nothing to do with past participles. In the context of this question, past participle "differed" can be used if this was referring to an event that took place in the past. But because it isn't, therefore it should be present participle instead. The fact that "differ" is a intransitive verb does not limit the construction of whether this sentence could be written with past participle modifier.

I did not follow in detail the discussion , but I try to give simple tip :

Option D : determined by when the sun reached the observer's meridian and differed

so you can say local times "were" determined by ... and "were" differed (from city to city) (The second part of sentence does not make sense)

Whatever type of verb Differ is, it is awkward in passive voice;

Option E : determined by when the sun reached the observer's meridian and differing

so you can say local times "were" determined by ... and "were" differing (from city to city) (Both part of sentence do make sense) ; Option E uses past participle and present participle respectively.

Question option C :

which were determined by when the sun reached the observer's meridian and differing

Which were can be applied to second part or not ? I feel it is parallel , though it is wordy and should be eliminated on grounds of style.
