In the August issue of PEN, we inadvertently printed two incorrect letters in our answer key on page 17.
- The correct answer to question 3 is B (17,000).
- The correct answer to question 5 is B (12 hours).
In both cases, the text of the answer is correct; only the letter was incorrect. The online version of PEN has been corrected, this applies to the printed copy only.
