Explanation:

To determine why the Fair Labor Standards Act was significant, we analyze each option:

• "It was easy for children to understand" is irrelevant as the text doesn't mention children understanding the law.
• "It was disliked by business leaders" shows opposition, not significance.
• "It became a law long ago, in 1938" is just a fact about when it was passed, not why it was significant.
• "It affected workers in important ways" matches the text's statement that the law "changed workers’ lives in important ways", explaining its significance.

Answer:

D. It affected workers in important ways.
