Question

what could be another title for the section \changing immigration rules kept foreigners waiting\?
○ \difficult entries, difficult exits\
○ \a famous gift\
○ \jewish refugees or german spies?\
○ \frank obtains visa\

Explanation:

The original title focuses on changing immigration rules affecting foreigners waiting. The option "Difficult Entries, Difficult Exits" directly relates to the challenges of immigration (entry/exit) tied to changing rules, matching the core theme. The other options are too specific to individual events or tangential questions, not capturing the broader immigration rule change theme.

Answer:

A. "Difficult Entries, Difficult Exits"
