Response
Now, did a quick Ctrl F through some stuff I did for school a few years ago. The first time I found the word Response it was in 5th grade.
From this I can conclude that if a 5th grader can spell Response, and presented with the fact that you cannot spell response, you must then be of an age less than that of a 5th grader. In 5th grade, students are usually 10 – 11 years old. Therefore you are less than 10-11 years old, and so you are 9-10.
