Option 1: This option states that Vivekananda exposed the weaknesses of Hindu culture, which forced Indians to think about its revitalization. This is not entirely accurate as Vivekananda focused more on highlighting the strengths and positive aspects of Hindu culture rather than discussing its weaknesses.

Option 2: This option suggests that Vivekananda infused humanistic values of western culture into Indian culture, thereby injecting fresh life into it. While Vivekananda did stress the importance of embracing scientific and technological advancements, his primary focus was on promoting the spiritual and philosophical aspects of Hindu culture.
