Here is reality for you...
A question like that would never be in a textbook for any kid to read.
Because it would have been AXED the moment it was seen.
What folks don't understand is there is a process for that text book to even reach a student.
It starts at the state level.
The head of education at the state level, the state house and senate and the PUBLIC including educators, parents, activists and so on all are give opportunity to look over and review every single book being offered for submission by publishers.
There is no voting for book approval until that period of review during Spring Break and March (at least here in Texas).
Once approved.
The same process happens again with the local school board, community and activists.
This is suppose to be the same process for every state. To prevent mess like that from getting to kids.
The certain GOP here in Texas tried that mess with trying to erase Hilary Clinton, Helen Keller and claiming from 2009-2017 the USA had no President. It was approved and that lasted 2 days before it was overturned.
And a question like that is a RABBIT HOLE question. It would open a bigger can of worms on racism and all that stuff that the GOP wouldn't want opened. Because certain black folks would LOVE to explain why that stat is reality and indoctrination.
