What did Harry Harlow’s experiments tell us about child development? a) Children and young animals that receive external stimulation of comfort and contact do not learn to be independent.
b) Children and young animals can be raised without any external stimulation and develop normally.
c) Children and young animals that receive external stimulation do not develop any differently than those that do not receive external stimulation.
d) Children and young animals need to have external stimulation in the forms of contact and comfort to develop properly.

Ibelieve the answers are a and c.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.two years ago, when picking flowers in the mountains back of yosemite valley; i found a book. it was blotted and storm-beaten, all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however, many of the inner pages were well preserved. and although all were more or less stained and torn; whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today, its granite pages have been torn and blurred by the same storms that wasted the castaway book.
