The questions asks: Clearly state which pairs are significantly different and which pairs are not significantly different. You can see in the grouping, Nobel has the letter "A", Academy has the letter "A" and "B" and Olympic had just the letter "B". From my class we didn't come across one who had both letters so I am not sure how to write this.
