Final answer:
The level of government that can afford large-scale media advertising to greater inform voters about candidates is the federal level due to its larger budget and broader reach compared to local or state levels.
Step-by-step explanation:
Among the various levels of government, the one that can afford television ads, billboards, and newspaper articles to a greater extent and thus allow voters to get to know the candidates better is D) the federal level. This level of government typically has more resources and a broader reach than city, state, or county governments. Federal campaigns often have larger budgets, allowing for a mix of traditional broadcast media and newer platforms like Internet and social media. While local news has a vital role in community engagement, their budgets are generally smaller and can't compete with the financial capability of federal campaigns when it comes to mass media advertising. Moreover, the impact of media coverage on a national scale is significant in helping voters obtain quick information about the candidates and their platforms.
