Select the correct text in the passage.
Which detail from the passage best reveals the Baron's newfound perspective on living life?

(33) He was always attentive, always polite, and they were good friends.

(34) When the baby was born, it had but one effect on their relationship; they had something to talk about now.

(35) But by-and-by the husband began to reveal a certain energy. He had a sense of duty, and moreover, he was sick of being idle. He had a private income, but was in no way connected with politics or the Government. Now he looked round for some occupation which would fill the void in his life. He had heard the first morning call of the awakening spirits and felt it his duty to do his share of the great work of research into the causes of human misery. He read much, made a careful study of politics and eventually wrote an article and sent it to a paper. The consequence was that he was elected a member of the Board of Education. This necessitated hard reading in future, for all questions were to be threshed out thoroughly.
