Final answer:
The correct answer is option b. rebuts. The argument supporting the use of tax dollars to improve internet infrastructure for critical services rebuts the creation of a two-tiered system and aligns with net neutrality principles.
Step-by-step explanation:
The argument that tax dollars should be used to expand internet infrastructure for critical functions indeed suggests that a two-tiered system of broadband access should be avoided. Such financing would aim to prevent disparities between areas that have robust internet services and those that do not (often referred to as the "digital divide").
The student's argument aligns with the ideas of net neutrality, which asserts that all internet traffic should be treated equally, without giving undue advantage to entities that can afford to pay for faster service. This position argues against creating a system where only the well-financed can afford accelerated internet speeds, which would potentially leave smaller or less profitable services at a disadvantage, impacting the open and equal access nature of the internet. The student's argument aligns with the ideas of net neutrality, which asserts that all internet traffic should be treated equally, without giving undue advantage to entities that can afford to pay for faster service.
