I actually answered this question correctly in the time given. C,E,H

Not challenging.

The correct words for the blanks are (i) apprehension, (ii) escalated, and (iii) confiscatory.

Breakdown of the Blanks
- Blank (i): C. apprehension

The sentence describes citizens meeting with their senator to voice their concerns. The final part of the sentence states that taxes would become a negative thing and that individuals would keep "little of their well-earned income." This context implies a feeling of worry or anxiety about the future. Apprehension means anxiety or fear that something bad or unpleasant will happen. This word fits perfectly.
- Blank (ii): E. escalated

The second blank describes what would happen to the tax rates. The argument is that if they do something "any further," the taxes would become a problem. Escalated means to increase rapidly. This word fits the context of rising tax rates that are becoming a burden.
- Blank (iii): H. confiscatory

The final blank describes the nature of the taxes if they rise further. The phrase "allowing hard-working individuals to keep little of their well-earned income" is a definition of a type of tax. Confiscatory means taking or seizing property as if by authority. In this context, it describes a tax that takes away too much of a person's income, so much so that it feels like it's being seized. This perfectly aligns with the citizens' argument.
