Questions & Answers about مدلهایشان حاکی از اینکه یک گردباد ویرانگر شکل میگیرد، بسیار دقیق بود.
How exactly does hâki az in ke work here, and could I have used mabnâ bar in ke instead?
hâki az in ke means "indicating that" or "showing that," and is usually used when data, evidence, or signs point to a conclusion. You could grammatically use mabnâ bar in ke, but that phrase leans closer to "based on the premise that" and is more commonly paired with decisions, claims, or reports. For scientific models showing a result, hâki az in ke is the most natural fit.
Why is the word in ke necessary after hâki az? Can I just drop it?
You cannot drop it here. The preposition az (from/of) must be followed by a noun or a noun phrase. Because the thing being indicated is a full sentence—"a destructive tornado is forming"—Farsi uses in ke (literally "this that") to bundle that entire clause into a noun phrase so it can grammatically attach to az.
Why is the final verb bud (was) in the singular when the subject modelhâyeshân (their models) is plural?
This is a classic rule that's always good to review: in Farsi, inanimate plural subjects (things that are not human) usually take a singular verb. Since models are inanimate, using the singular bud is correct and sounds much more natural than the plural budand.
The English translation says "is forming," but Farsi uses the standard present indicative shekl migirad. Shouldn't it use the present continuous tense?
It is not strictly necessary. While Farsi does have a specific present continuous structure (which would be here), the standard present indicative (the prefix + present stem) is heavily used to mean both "forms" and "is forming." In subordinate clauses like this one, it is very common and natural to simply use the standard present indicative for an ongoing event.
