<span>Well, this question is the tricky one! Actually, there wasn't left any marks, it is the main problem of this story. So in “Elegy Written in a Country Churchyard” by Thomas Gray, NO marks have the forefathers left on history? and according to this fact the only one correct answer is definitely the third option from the scale represented above - The forefathers have left no mark on history, having led “noiseless” lives.</span></span>
The prepositional phrase is "on a high shelf" since ON is a preposition.
The answer is B :) hope that helps
