it has a strong impact on personal growth throughout life. This is the correct option.
Jane Addams , 1889, thinks that the present reactions of an adult may have originated in the past- during childhood-. During childhood one's character may not be well defined - formless- , yet it will influence one's future life - definite lines of future development-. Although experience during childhood may not construct a definite character, this experience will strongly influence one's growth.
These options are not right:
-its trials and triumphs will support a successful life. ( The author does not mention any trials or triumphs. Besides, she does not refer to success. She just says childhood expierence will influence growth).
-suffering during this time can create long-lasting goals. ( Addams sounds more genral; She does not refer to suffering or goals).
-children are free of the ethical judgments that adults make. ( Ideas about ethics or judgments are not made).
