Final answer:
It is not possible to accurately answer which option (more, less, equally, or occasionally likely) is correct for the US and India comparison or for the perception of closeness within current families without specific, current research data.
Step-by-step explanation:
The part of the question concerning the likelihood of children and adults in the US compared to children in India believing in an obligation to help strangers requires insight into societal and cultural norms, which can be complex and varied. Without specific research and current data to inform the answer, it would be unreliable to assert one of the options (a-d) as correct. The question seems to touch on cultural differences and social responsibility.
The second part of the question about people's feelings towards their current family could be influenced by a multitude of factors, such as personal experiences, social dynamics, and cultural backgrounds. Again, without specific research findings to reference, it is not possible to provide a factually accurate response to whether people generally feel their current family is more close, less close, or at least as close compared to some unstated standard or time. This part of the question looks at family relationships and closeness.
