Final answer:
The best approach for understanding cultural preferences of a family is through open and respectful communication, rather than relying solely on reading books.
Step-by-step explanation:
The statement 'If you are uncertain about cultural preferences of a family in whose home you are working, the best thing to do is to read many books about the culture and act according to what you learn through your reading.' is False.
While reading books about a culture can certainly provide valuable insights and knowledge, it is essential to remember that cultural preferences are unique to individuals and families. The best approach is to engage in open and respectful communication with the family, asking questions and seeking to understand their preferences directly. This way, you can avoid making assumptions based solely on what you have read.
