Jim wants to know whether allowing employees to take a work break might improve workplace satisfaction. In this research question, whether or not employees took a work break is which type of variable?

Explanation:

Taking a break, whether for lunch or an afternoon cup of coffee, is an essential part of most people’s workdays. Research has shown that building breaks into our day helps keep us sharp and productive on the job. In many offices, the typical culture is to work throughout the morning, with breaks saved for lunch or the late afternoon. Hunter and Wu hypothesized that – much like workers all over the world – people get the most out of taking a break once they’ve already been hard at work for most of the day. But, after analyzing data collected from nearly 1,000 breaks, they found that a mid-morning break provides far more benefit than a late afternoon one. Hope that helps!!!

the correct answer is d.

hope this
