Answer:

The idea unsupported by the author's main arguments about Benjamin Franklin's accomplishments is Benjamin Franklin's Fascination with Electricity  adapted from the National Park Service  paved the way for  theories about  electricity.

Explanation:The Statement that Benjamin Franklin was fascinated by electricity and gave a lot of his time after he retired  study its properties is true because he started studying the properties of electricity in 1746 and devoted more time to it after retiring in 1788. He conducted his famous kite experiment in June 1752. Also, the statement that he never patented any of his inventions is also true and is supported by authors arguments. Franklin's influence in the early history of the United States has led people to call him "the only President of the United States who was never President of the United States". He is largely self educated because though he attended the school he did not graduate, but continued his education through voracious reading.

Answer:

the only president who was never elected president

Explanation:

This wasn't mentioned in the author's argument and none of the elements of an argumentative structure involved that claim.

1. The title implies that the passage will focus on Benjamin Franklin's fascination with electricity, not his political influence or affiliations.

2. The central claim is the following: "Benjamin Franklin was fascinated by electricity and gave a lot of his time after he retired to study its properties." This restates that the focus will remain on B.F.'s fascination with electricity.

3. His non-presidency wasn't even mentioned in the passage. If it was, it would make a poor supporting claim for the topic.

Other Options:

  • paved the way for theories about electricity
  • largely self-educated
  • never patented any of his inventions

Here's the passage for reference:

Benjamin Franklin's Fascination with Electricity

adapted from the National Park Service  

    Benjamin Franklin was fascinated by electricity and gave a lot of his time after he retired to study its properties. Some of his research resulted in "tricks" that he used to amuse others. For example, he made a charged metal spider that moved like the real thing. He discovered new ways to generate, store, and turn on electricity. His design of lightning rods helped prevent untold numbers of structural fires throughout the world.

    His famous kite experiment occurred in June 1752. Franklin asked his son William to fly a kite to which he had attached a wire on top and a key at the end of a string. Ultimately, the kite gathered an electric charge from a storm cloud. Franklin was then able to collect some of the charge and compare it to the electricity he had created in other experiments. He did not mention the experiment until October, four months after it took place, at which point Franklin did not clarify that he had conducted the experiment himself—an issue that has caused some people to doubt Franklin's story.

I also got this question correct on Edmentum. I hope this helps!
