One of the most significant challenges is building an airplane had to do with "propulsion", since the technology that allowed motors to have enough energy to lift an airplane into the sky with a passenger wasn't available for most of history.
Answer:
The privilege of the writ of habeas corpus shall not be suspended, unless when in cases of rebellion or invasion the public safety may require it.
Explanation:
The suspension of the Habeas corpus in this case is supported by the US constitution, through the common law. This suspension can be seen in article 1, section 9 and clause 2 of the constitution.
It is important to emphasize that Habeas corpus is the term that refers to the judicial measure that allows and protects the freedom of movement of any individual, even if that individual is threatened, or limited by something.
Assuming you're pro-Columbus day, these are points that can be made:
Being historically accurate, Columbus day should be celebrated because he attempted and was successful at colonizing and helping America grow.
A common argument trying to counter being pro-Columbus day is the mention of killing Native Americans, so you can mention that diseases had already existed and were the primary cause of death in the New Land rather than Natives being killed (keep in mind though that disease and murder were both factors).
Another Pro argument that could be made is the fact that yes, vikings DID find America first, however Columbus helped Americas economy, etc.
Assuming you're anti-Columbus day, these are more points:
What Christopher Columbus did to Native Americans is unjust, essentially he took land from the Natives and they were forced to convert and change their lifestyle in order to work with Columbus or were killed; brutality is unacceptable.
The day itself should be focused on the Native American victims of Columbus.
The vikings technically found the New Land.
I hope this helped a little! :)
Depends on the country, for example the UK Prime Minister is elected by the public.
Hope this helps.
