VTechTouch And Teach Word Book Amazon Exclusive, Pink

Does this book teach letters, shapes, colors, or numbers? Or what are the main categories of words?

Are the batteries already in the toy? I'm giving this as a gift and the box says try me, but when I did, it doesn't work.

I ordered this book for my niece and when I touch the left pages the words does not get selected. Is this normal or I have been sent a defective piece

How many pages does the toy have?
