You're behind schedule and opening boxes with your coworker. She says that the blade on her box cutter is dull.

a. Ask her if she has a spare blade to replace the dull one.
b. Suggest using your box cutter instead since it has a sharper blade.
c. Advise her to report the issue to the supervisor for a replacement.
d. Offer to sharpen the blade using a sharpening tool.

If your coworker's box cutter blade is dull, she should be asked if she has a spare blade. Using your own box cutter or reporting the issue to the supervisor are also possible solutions.

Explanation:

If your coworker informs you that the blade on her box cutter is dull, you should advise her to:

a) ask if she has a spare blade to replace the dull one. This is a practical solution that can quickly solve the problem and allow both of you to continue opening the boxes efficiently.

b) Suggesting using your box cutter instead since it has a sharper blade might seem like a helpful gesture, but it can lead to confusion and potential accidents.

c) Advising her to report the issue to the supervisor for a replacement is also a valid option, especially if replacement blades are not readily available. However, it might take some time before a new blade is provided.
