题目内容：
Questions are based on the following passage． For years, high school students have received identical textbooks as their classmates．Even as students have different learning styles and abilities, they are force-fed the same materials．"Imagine a digital textbook where because I'm a different person and learn differently, my book is different than your book," said Richard Baraniuk, founder of OpenStax．
OpenStax will spend two years developing the personalized books and then test them on Houston- area students．The books will also go through a review and evaluation process similar to traditional textbooks．Baraniuk expects 60 people to review each book before publication to ensure its quality．
The idea is to make learning easier, so students can go on to more successful careers and lives．Baraniuk isn't just reproducing physical textbooks on digital devices, a mistake e-book publishers have made．He's seriously rethinking that the educational experience should be in a world of digital tools．To do this means involving individuals with skills traditionally left out of the textbook business．Baraniuk is currently hiring cognitive scientists and machine learning experts．Baraniuk wants to use the tactics (策略 ) of Google, Netflix and Amazon to deliver a personalized experience．These Web services all rely on complex algorithms (算法) to automatically adjust their offerings for customers．Just as Netflix recommends different movies based on your preferences and viewing history, atextbook might present materials at a different pace．The textbook--which will bestored on a range of digital devices--will automatically adjust itself thanks to machine learning．As a student learns about a topic, he or she could be interrupted by brief quizzes that evaluate whether he or she masters the area．Depending on how the student does, the subject could be reinforced with more material．Or a teacher could be automatically e-mailed that the student is struggling with a certain concept and could use some one-on-one attention．
This personalized learning experience is possible thanks to the wealth of data a digital textbook can track．This data can be used to better track students' progress during a course．Parents and teachers can monitor a student's development and provide in time more proper assistance．With personalized learning methods, our students' talents will be better developed．
What do we learn about personalized books?_______ A．Their quality will be ensured since they are developed by OpenStax．
B．They will be examined and judged before being published．
C．They will overlook different learning styles and abilities．
D．They will be much similar to traditional textbooks．
