Question

select the misplaced or dangling modifier. generating power naturally, without fossil fuels, conservationist john muir was said to have been an admirer of nikola teslas hydroelectric power system.

Explanation:

A dangling modifier is a phrase that modifies a word not clearly stated in the sentence. Here, "Generating power naturally, without fossil fuels" is a participial phrase intended to modify Tesla's hydroelectric system (which generates power that way), but it's placed before "conservationist John Muir", making it seem like John Muir is generating power, which is incorrect. So the misplaced/dangling modifier is "Generating power naturally, without fossil fuels".

Answer:

Generating power naturally, without fossil fuels
