Children write, word for word, what they read, they click on the rating and wonder! They rely on the low level of education in public and private vocational schools, on the lack of judgment of readers, and on the mostly teachers who may suggest this, just to save themselves the trouble of preparing the answers! It is a shame for someone who wants to be called a "scientist" to publish such mistakes and inaccuracies, without the assistance of an interdisciplinary team. It is a shame for a publishing house to publish something that can destroy a student.
