3. What's an impact of automation? A. Greater economic equality B. Higher tariffs C. Lost jobs D. Reduced taxes

The impact of automation can be seen in various aspects of society. However, looking at the options provided:

A. Greater economic equality - This is not necessarily true. While automation can lead to increased productivity and efficiency, it does not guarantee greater economic equality. In fact, it could potentially lead to greater inequality if the benefits of automation are not distributed evenly.

B. Higher tariffs - Tariffs are taxes or duties to be paid on a particular class of imports or exports. They are not directly related to automation.

C. Lost jobs - This is a significant impact of automation. As machines and technology continue to advance, they can potentially replace human workers, leading to job losses.

D. Reduced taxes - Automation does not directly lead to reduced taxes. Tax rates are determined by government policy and are not directly influenced by the level of automation in a country.

So, the most accurate answer would be C. Lost jobs.
