Questions using throughline
Problem 1
What is a 'throughline' in an extended essay?
- The alphabetized list of every source, provided at the end.
- A colorful anecdote used to open the essay.
- The central claim threaded visibly through every section, so the reader always knows what the essay argues and why the current page matters to it.

Answer and explanation
The central claim threaded visibly through every section, so the reader always knows what the essay argues and why the current page matters to it.
A throughline is the sustained central claim woven through the whole essay so the argument never drifts; it is not a sentence's length, a source list, or an opening anecdote.
