Read this excerpt from chapter 1 of wheels of change by sue macy. inventors began to explore the idea of attaching cranks or pedals to the velocipede's wheels as early as the 1820s. although a few made successful models for personal use, no one developed a prototype that gained widespread acceptance until the 1860s. some attribute the breakthrough to ernest michaux, a french carriage maker, though others credit pierre lallement, who worked for him. at any rate, the new velocipede was propelled by pedals and cranks attached directly to the axel of the front wheel, which was slightly larger than the wheel behind it. forward progress could be stopped or slowed by pedaling backward. what chronology is described in the excerpt? the gradual improvements in bicycle design the process of attaining design patents the increasing competition among bicycle companies the progression of adding safety features to bicycles

We can answer to this question by singling out incorrect options. It is obvious that the excerpt is about the development of bicycle or first bicycles. Therefore, there is no competition, yet. We don't have any information about a successful trial or patent after that. The excerpt describes the development of sufficiently working, a useful bicycle. Of course, the developers would have considered safety features, but we don't observe it in this excerpt. The correct answer is the first option -  the gradual improvements in bicycle design.

samuel gompers was an extremely important person in the american labor movement, being him an employee all his life he devoted himself to fight for the rights of his pairs, he believed they all had the right to have better thing and that they all were working for them but the factory workers were greedy, ambitions and socialist people for him who he didn't have a good concept of.

he gave so many speeches and led so many strikes and protest to fight for equality which he considered employers didn't want to accept, so he had an absolutely negative opinion of them.
