Question: What did OMB hope to provide with their revision on race and ethnicity in 1997?
Sentence: Among the changes, OMB issued the instruction to "mark one or more races" after noting evidence of increasing numbers of interracial children and wanting to capture the diversity in a measurable way and having received requests by people who wanted to be able to acknowledge their or their children's full ancestry rather than identifying with only one group.
Answer in sentence: no
