What are the similarities between the 1960 and 1963 constitution of nigeria

Not a great deal.  We’ll use 1960 as a baseline.  Between 1960 and 1963, one Amendment was ratified.  The 23rd Amendment made it possible for the citizens of the District of Columbia (Washington DC) to vote in Presidential elections.

Between 1963 and 1979 (why 1979?), 4 Amendments were ratified.

The 24th Amendment barred Poll Taxes

The 25th Amendment dealt with Presidential Disability and Succession

The 26th set the Voting Age to 18.

That’s it.  All the changes to the US Constitution between the years 1960, 1963 and 1979.  Now maybe you can elaborate why those years are significant?

The correct answer is - C) military force.

The protests for democratic reformation of China in the Tiananmen square where not seen fondly by the Chinese government. They decided to use military force in order to destroy the protest, and it was not just to move the people away or scare them off, but it was very brutal. Lot of people that were protesting were actually killed the by the military, and that was supposed to serve as an example for any other people in the country that would try and do something like that.

The protest was dominated by young people, students in general, and unfortunately, their will for better and free life meant death for lot of them.
