Final answer:
Kenny is most uncomfortably unaccustomed to religious rituals in Rukmani's house, which reflects the wider challenges faced by outsiders when immersing in new cultural and religious practices.
Step-by-step explanation:
In Rukmani's house, Kenny is obviously uncomfortably unaccustomed to c) Religious rituals. Kenny, being an outsider, finds the cultural practices and the deep-seated religious customs of Rukmani's family life to be outside his experience and comfort zone.
When immersing oneself into a new culture, aspects such as agriculture, domestication of animals, or use of language can be challenging; however, religious rituals often carry profound significance and require a deep understanding of local traditions and beliefs, which can be particularly difficult for an outsider to grasp fully.
In the novel 'Nectar in a Sieve' by Kamala Markandaya, Kenny, the foreigner visiting Rukmani's house, is obviously uncomfortably unaccustomed to speaking the local language. The passage states that Caitlin had studied Spanish in school for years, indicating that she was fluent in a different language. This lack of familiarity with the local language would make it difficult for Caitlin to communicate effectively and understand the conversations happening around her.
