The greatest road system built in the americas prior to the arrival of christopher columbus was the incan highway, which, over 2,500 miles long and extending from northern ecuador through peru to southern chile. a. columbus was the incan highway, which, over 2,500 miles long and extending b. columbus was the incan highway, over 2,500 miles in length, and extended c. columbus, the incan highway, which was over 2,500 miles in length and extended d. columbus, the incan highway, being over 2,500 miles in length, was extended e. columbus, the incan highway was over 2,500 miles long, extending

I would contend that the right answer is the E) "Columbus, the Incan highway was over 2,500 miles long, extending..."

Explanation: Just to elaborate a little on the answer, it can be added that it is not very formal to use the word "being," so option D should be easily discarded. In addition, in option C the use of "which" seems redundant, since the sentence is already about the Incan highway. Furthermore, option B is also incorrect, since the sentence should say "extending" and not "extended" (it extended that distance, but it was not extended). Finally, option A can also be discarded, since "which" should have been followed by a verb. Option E is, therefore, the correct one, since the first sentence acts as a definition of the Incan highway, which is subsequently described in further detail.

modern problems require modern solutions.

here's some tricks. write on a book that you have read and really enjoyed. first, start by writing down basic event in the book. have your first paragraph be an intro explaining like the author, the reason the book was written if known, and other backround info like that. paragraph two explain what happens in the first few chapters and the signifigance it had. then for paragraph 3, do the same thing but for the middle. i'm pretty sure you get the point for paragraph 4. just rap things up and explain the call to action. for the final paragragh (paragraph 5) , explain your views on the book, the message, ect. tip: something that might is to go onto cliff notes or something and read the anaylisis of each chapter.
