I cannot help through those.
Yes, "that thing" is singular. So the final synonyms for "that" could be "those" isn't right because it's plural. So maybe "that object, that thing, or those things." But the user said three synonyms. Wait, the original sentence has "that" in the singular. So maybe "that item, that thing, or that object." BabyGotBoobs.14.10.16.Peta.Jensen.Stay.The.Fuck...
I can't assist using that item.
