Hello, Lee Mcgee
This test of "reading it alone" is not fair at all.
The ability to read a text without vowels is not based on the shape of the letters, but it is based on the vocabulary knowledge, And most of all, on the knowledge of the grammatical pattern and syntax.
The shape of the letters says nothing.
And so, you cannot make this kind of test.
As for the issue itself...
Every Hebrew reader can read without vowels, and this is how the Hebrew is read since the beginning.
Mishna, Talmud, (also the Talmudic Aramaic), books, and so on.
Once one speaks the Hebrew language, it is easy for him to read it without vowels marks, exactly like an Arabic man reads Arabic without vowels marks.
The vowels marks were added to the Bible because it is sacred and the accuracy is essential for those who see it like that.
And I already know the answer, which I don't accept, that This is Biblical and This is not.
And so, it doesn't matter, because the Hebrew reader is easy to understand the pattern easily.
And you can check it for yourself.
Here is a story that was written a few centuries ago, in Biblical Hebrew
https://benyehuda.org/mapu/ahavat_zion_complete.html
If you wish to test one's knowledge in Biblical Hebrew, then you should ask if he can read this.
This is Biblical Hebrew with no vowels.
And if a man can read it with no vowels, then he can read also the Bible with no vowels.
And if he can't, then he also cannot read the Bible, and just thinks he can, because he uses translations next to it to help him.
The Biblical can sometimes be harder to read also for a Hebrew reader, Not because he doesn't have the knowledge of the pattern, but because sometimes the Biblical text is written is a "short way" or with a lot of poetic styles, and so it can make it harder to understand, just like any poetic text can be harder to understand.
But that is not because of lack of knowledge, but because the text itself, objectively, is written in a hard style to understand.
Another test is any kind of Hebrew with no vowels, like Ben Sirah, or the Qumran scripts (not the Biblical ones).
The Aramaic text you wrote, probably can be read easily by those who read Aramaic naturally. But it maybe has a lot of "strange" patterns which are different from the patterns on other Aramaic dialects.
So to sum things up,
Each language (Hebrew, Aramaic, Arabic) is based on patterns.
The shape of the letters is not important.
So for testing one's knowledge in Hebrew (Biblical or not), you should give a text that uses the same pattern or close to it.
