Textbook errors must be corrected

We appreciate the government's efforts to improve the quality of education in Bangladesh, but we must also bring to light the mistakes

We appreciate the government's efforts to improve the quality of education in Bangladesh, but we must also bring to light the mistakes that are occurring, which reflects the negligence of those involved in the various stages of writing, editing, and printing these textbooks. 
My son is in the fourth grade. While comparing his current science book to the science book of 2014, I found question exercises related to the content published in the 2014 textbook. Other questions seemed to have no connection to the content of the current book. It is wrong to prepare books for children by resorting to mere “cut and paste” techniques. Our government must prevent these practices immediately.
