Hi forever 21!
I agree with all your answers except Qn1. I think the answer is C
The author mentions maps of newly discovered passages in the passage as example of
a. information sources contributing to the 1st census
b. early evidence of careful record keeping
c. information kept secret by some nation
d. the only surviving records of early civilization
Any figures indicating a nation's military and economic power were guarded as state secret, like the maps of newly discovered passages through dangerous water to distant ports.
For Qn 11, I think the sentence should come between "The ancient population counts among the egypyian, greeks, hebrews....." and "A different kind of accounting was the goal in the earliest recorded....."
What do you think?
