Which of the following choices is a strategy that can help speed up reading?

A. external distractions
B. Using a penor pencial as a pacer
C. Use subvocalization

I think both B and C are correct. But I could only choose one answer. What do you guys think the answer should be?

Thank You.

I don't like any of the possible answers.

However, if I had to choose one of the above, probably B is best.

Subvocalization would slow down the reader.
