Which two words in the passage are academic words? General Sherman is one of the world’s largest largest giant sequoia trees. A naturalist named it after Civil War General William Sherman. The General Sherman tree has an estimated circumference of more than 100 feet. Its height exceeds 270 feet.
I believe the two words are circumference and naturalist. However, the term "academic word" is a very broad umbrella category and these words can be used on a day-to-day basis, so please don't quote me if I am incorrect.
