Is that a typo? Do you mean Programming_Language_1 is sufficiently low level?
Recall that the approach is to translate instances of Programming_Language_2
to instances of Programming_Language_1.

I will assume you meant Programming_Language_1. So you are saying that the
target language (Programming_Language_1) must be a lower level language than
the source language (Programming_Language_2), right?

How to determine if two source languages are semantically similar?
