I think the ________ is mre imprtant than _______. Here’s why: First, __________________. Secnd, _________________. Third, __________________________________________. In shrt, ____________________________________.
1. Which inventin d yu think is mre imprtant, the printing press r the light bulb? Why?
I think the printing press is mre imprtant than the light bulb. Here’s why: First, bks became much cheaper and easier t make than befre. This let mre peple learn t read and share ideas faster than ever. Secnd, it changed the mst basic way humans learn. Withut it, schls, science and even mdern inventins like the light bulb might nt exist tday. Third, the printing press spread knwledge wider and mre pwerfully. It helped create the mst imprtant changes in histry. In shrt, the printing press didn’t just make life better—it made prgress itself pssible. That’s why I believe it’s the mre imprtant inventin.

I believe cmputer is the mst imprtant inventin. Here’s why: First, cmputers let us study, wrk, cmmunicate and create—all with ne machine. Secnd, they changed the wrld faster than any ther inventin. Fr example, students frm different places can get educatin nline mre easily. Mst imprtantly, cmputers create new pssibilities. Withut them, we wuldn’t have the Internet, mdern science r even self-driving cars! In shrt, cmputers tuch mre parts f ur lives and drive the biggest changes. That’s why they’re the mst imprtant inventins.
(3) What ther inventins d yu think are as useful as thse n the list?
I think  ________ is as useful as thse n the list.
