I would say Andrew Johnson he was the president during that time. meaning he was the president when the 14th admindment was made (14 admindment made everyone born human a citizen and wpuld be treated equally)
Answer Andrew Johnson
We can use a current event for this one. Recently, the United States along with a few other countries have expelled Russian diplomats from their countries. Therefore, we have,
"In the recent days, countries like the US and the UK have expelled Russian diplomats from their countries, sparking a global effort to do the same."
This relates to the international organization because it talks about a break of unity between these countries that abrupt;y breaks diplomatic relations that previously were existent and well.
Hope this helps!
