Answer:
<em>Omniscient third person.</em>
Explanation:
The omniscient third-person point of view is characterized by a narrator that always knows everything - what is happening, what the characters in the story think and do, he has an answer to any possible question because he is a know-it-all. This perspective in writing is very useful when the storyline is complicated and there is a lot of characters that need to unite that story and all of its events.
In the given example, the narrator not just sees what the character is doing, but also what she is thinking, planning, etc, so it matches the characteristics of the omniscient third-person point of view.

6. Here, the verb "analyzing" is taken as a gerund, thereby functioning as a noun. And so, the helping verb used will be "is".
7. Similarly, this sentence contains the noun "economics" which is a branch of study and thereby taken as a singular noun. Thus, the verb will be "is".
Thus, in all three sentences, the helping verb used will be "is".
