Question

where is the bold thamo being used in the sentence?
rafiki had never been on a boat before;
bold{nonetheless}, he decided to spend his summer
sailing around hawaii.
between two complete thoughts
interrupting one complete thought

Explanation:

A THAMO (Therefore, However, As a matter of fact, Meanwhile, Otherwise) is a conjunctive adverb that connects ideas. In the sentence, "Rafiki had never been on a boat before" is a complete thought, and "he decided to spend his summer sailing around Hawaii" is another complete thought. "Nonetheless" (the bold THAMO) is between these two independent clauses (complete thoughts), separated by a semicolon and a comma. It's not interrupting one thought as it's not placed within a single clause.

Answer:

Between Two Complete Thoughts
