Question

What is one effective way for employees to keep their skillsets current?

Answer 1

The correct answer is B. Read journals online or subscribe to them

I got this answer correct

Answer 2

They are probably looking for B.  subscribing to journals is a good way of keeping up with what's happening in any field.

Of course, a very carefully curated professional network online is great for this too (but they said "personal" so that's not the answer)

Employers generally prefer that employees WORK as often as possible, so even though JUDICIOUS use of social media is a great way to keep current, D isn't the answer either.

Blogging about personal experiences is not necessarily going to teach you anything about work, though blogging professionally can be useful in gathering response from your readership
