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.

b because i dont see anything

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
