Answer:
Option B
Explanation:
Question -
You just came back from class in which the topic was egocentrism in the preoperational stage. You have a 4-year-old and thought that you would see if what you learned was accurate. You are sitting directly across from her and ask her to look at the front and back cover of her favorite book. After she did this you asked her to describe "the part of the book I am looking at." What does she tell you?
a) how many pages there are in the book
b) what she sees
c) what you see
d) what the story is about
Solution
As per Piaget's theory of cognitive development, when a child is at the preoperational stage he/she is able to think only at symbolic level and cannot use his/her cognitive thinking.

A) .was immediately accepted
Explanation:
The theory of plate tectonics was immediately recognized as the explanation for the moving continents. It provided a more scientific background as why continents drift apart and the seafloor keeps spreading.
- The theory explains that the earth is broken up into series of slabs called lithosphere which moves on the weak, ductile and fluid asthenosphere.
- The movement of part of the earth mantle provided the mechanism through which the lithosphere moves. This is now known as the mantle convection.
- This theory provided a scientific mechanism through which the plate moves and seafloor spreads.
- It was immediately accepted when the theory was propounded by Alfred Holmes in the 1930s
