Well this is a very opinionated question but personally:
Astronauts improve society by using the newest and most expensive technology to be able to explore space as we know it.
Lutherans from Germany, Calvinists from France, Baptists from England, and a whole host of other Christian sects all eventually became known as Protestants. The word ''protestant'' sprung up out of the political conflict in the Holy Roman Empire in the sixteenth century.
I am pretty sure that the answer for the first question is A. Both empires shared similar laws and traditions because The West and East used the same laws and Eastern Roman Empire continued using them.
The second one is definitely b. It serves as a day of rest and worship. as it is main points of hajj for Muslims.
The third is b. a monk who defended the use of icons.
And what about the last one - b. Muslim non-Arabs were granted more privileges than Muslim Arabs. This quite a triky question, but the think you should remember is that Muslim non-Arabs were treated better.
No because it was a dangerous expedition
