A family does this when they move to a new country and learn its customs and traditions. The word is (6)

adapting/adaptation? this is a blind guess, but people adapt to cultures when they learn new traditions and such. Hope this helps. :)

Explanation:

the examples that saki used to represent satire through situational irony are options two (2) and five (5) inasmuch as the wolf thought that looking for a girl in the bushes could be as easy as hunting little pigs at the park, but it took him so much time to find the girl if it had not been not for a silly mistake. also, bertha would have survived to the wolf's hunt if she had not won those medals for goodness, which at the end they were what got her killed by making noise, so winning medals of goodness was not so good achievement, after all.

i think the first one, it makes the most sense.
