Read this passage from a newspaper editorial whose purpose is to persuade an audience ofeducators. as you read, identify the best replacement for the bold words and phrases to match the desired style and tone of this editorial.

in years past, educational systems often focused exclusively on mainstream culture. these systems
focused on teaching from one cultural group and its traditions, suggesting then
that other cultural groups and their traditions were not worth studying. goodness that trend
is changing. as educational systems increase their acceptance of other people's family traditions
. we will probably see educational materials that include more authors
who might fall outside the accepted bunch of school resources
offering students a heap
of voices to learn from and enjoy.
