Answer:
B. Aylmer will be able to love his wife and science equally.
Step-by-step explanation:
The speaker describes the feelings of a scientist from the last part of the last century -XIX: the century of science-. The scientist love towards scientific knowlede is what makes him intelligent. This passion will lead him to high complex thoughts. However, this passion can be weakened by the passion felt towards a woman. This is Aylmer's case. In the speaker's opinion, though, this love the scientist feels towards his wife is deep because his love towards science is. The strengthof one love feeds the strength of the other love. This is reflected in these lines: "...His love for his young wife might prove the stronger of the two; but it could only be by intertwining itself with his love of science and uniting the strength of the latter to his own."
