Answer:
The entire absolute phrase in the sentence is "eyes glittering with concentration".
Explanation:
After reading it, we realize that "eyes glittering with concentration" refers to the sentence as whole. That is what makes it an absolute phrase - instead of modifying just one noun, it modifies a whole sentence. In this case, we can imagine Jack moving his cursor while his eyes glitter, showing how focused he is.
Absolute phrases' structure include a noun or a pronoun followed by a participial phrase. For example: hands trembling with nervousness. Notice that "eyes glittering with concentration" follows that structure.
Participial phrases consist of a participle and modifiers. For example: running out of energy.
Answer: Know your sources. Is it reliable? Especially for research projects, you should definitely be careful of which one to use. For example, a lot of teachers will say not to use info off of Wikipedia since anyone can edit an article regardless of what certification they have (even those who don't study in that field, literally anyone). And make sure to credit them, you're going to avoid plagiarism. I wouldn't really call these restrictions, they're just important ethics to follow.
