write it right
I consider that there are five important events.............totally different.If Christopher Colombus had not discovered the new world,the entire world would not have had many conflicts that disturbed a lot of countries.Moreover,if the Industrial Revolution had not occured,we would have used traditional tools.In addition to this,if Karl Marx had not written the communist manifesto,we would not have known about conflicts between social classes.Besides,if the anti-colonialist struggle had not existed ,people before would not have taken their independence easily.Finally,if the computer had not been developed,we would have faces many obstacles to undertake our research.In conclusion,I suppose we should be thankful for some of these events that made a radical change in people's life
Best of luck
